Definitions
- the present invention relates to a hot-press steel plate suitable for manufacturing a member such as an automobile undercarriage member and a vehicle body structural member by hot pressing, and a hot-pressing member manufacturing method using the hot-press steel plate.
- Patent Document 1 discloses a hot press that enables both easy processing and high strength by simultaneously processing a heated steel plate using a die and a punch and simultaneously cooling it.
- a so-called processing technique has been proposed.
- scale iron oxide
- the steel plate is heated to a high temperature of around 950 ° C. before the hot pressing, scale (iron oxide) is generated on the surface of the steel plate.
- the scale generated on the surface of the steel plate is peeled off during hot pressing, thereby damaging the mold. Or the surface of the member after hot pressing is damaged. Further, the scale remaining on the surface of the member causes poor appearance and poor paint adhesion.
- Patent Document 2 discloses a hot-pressed member excellent in corrosion resistance in which a steel sheet coated with Zn or a Zn-based alloy is hot-pressed and a Zn-Fe-based compound or a Zn-Fe-Al-based compound is provided on the surface.
- a manufacturing method is disclosed.
- Scale formation is likely to occur at local sites such as cracks originating from a defective portion of a plating layer or a Zn-Fe metal compound formed during heating by hot pressing.
- Scale and ZnO are likely to occur in a Zn-based plating layer having a low melting point of less than 700 ° C.
- the present invention has been made on the basis of the above knowledge, and a plating layer containing 10 to 25% by mass of Ni on the surface of the steel sheet, the balance being made of Zn and inevitable impurities, and an adhesion amount of 10 to 90 g / m 2
- a steel sheet for hot pressing characterized by comprising:
- the plated layer further has at least one compound layer selected from a Si-containing compound layer, a Ti-containing compound layer, an Al-containing compound layer, and a Zr-containing compound layer. Is preferred.
- the steel sheet before the plating layer is provided, that is, the base steel sheet for the plating layer, in mass%, C: 0.15 to 0.5%, Si: 0.05 to 2.0%, Mn: 0.5 to 3 It is possible to use a steel sheet containing%, P: 0.1% or less, S: 0.05% or less, Al: 0.1% or less, and N: 0.01% or less, with the balance being composed of Fe and inevitable impurities.
- the base steel sheet is individually at least one selected from Cr: 0.01 to 1%, Ti: 0.2% or less, B: 0.0005 to 0.08%, and Sb: 0.003 to 0.03% by mass. Or it is preferable to contain simultaneously.
- the present invention also provides a method for producing a hot pressed member, wherein the hot pressed steel sheet of the present invention is heated to a temperature range of Ac 3 transformation point to 1000 ° C. and then hot pressed.
- the hot press member manufactured by the method for manufacturing a hot press member of the present invention using the steel sheet for hot press of the present invention has a good appearance and has excellent paint adhesion and corrosion resistance. It is suitable for members such as rotating members and vehicle body structural members.
- the steel plate surface contains 10 to 25% by mass of Ni with the balance being Zn.
- a plating layer made of inevitable impurities is provided.
- the Ni content of the plating layer is 10 to 25% by mass, a ⁇ phase with a crystal structure of Ni 2 Zn 11 , NiZn 3 or Ni 5 Zn 21 and a melting point as high as 881 ° C is formed. Therefore, it is possible to minimize the generation of scale and ZnO during heating. Further, since no Zn—Fe metal compound is formed during heating, the generation of scale associated with the occurrence of cracks is also suppressed.
- the plating layer having such a composition since the plating layer having such a composition remains as a ⁇ phase even after the hot pressing is completed, it exhibits excellent corrosion resistance due to the sacrificial anticorrosive effect of Zn.
- the formation of the ⁇ phase when the Ni content is 10 to 25% by mass does not necessarily match the equilibrium diagram of the Ni—Zn alloy. This is presumably because the formation reaction of the plating layer performed by electroplating or the like proceeds in a non-equilibrium manner.
- the ⁇ phase of Ni 2 Zn 11 , NiZn 3 , and Ni 5 Zn 21 can be confirmed by an X-ray diffraction method or an electron beam diffraction method using TEM (Transmission Electron Microscopy).
- the ⁇ phase is formed as described above by setting the Ni content of the plating layer to 10 to 25% by mass, some ⁇ phase may be mixed depending on the conditions of electroplating. At this time, in order to minimize the generation of scale and ZnO during heating, the ⁇ phase content is preferably 5% by mass or less.
- the ⁇ phase content is defined by the weight ratio of the ⁇ phase to the total weight of the plating layer, and can be quantified by, for example, the anodic dissolution method.
- the adhesion amount per one side of the plating layer is 10 to 90 g / m 2 . This is because when the adhesion amount is less than 10 g / m 2 , the sacrificial anticorrosive effect of Zn is not sufficiently exhibited, and when the adhesion amount exceeds 90 g / m 2 , the effect is saturated and the cost is increased.
- the method for forming the plating layer is not particularly limited, but a known electroplating method is suitable.
- the thickness of the compound layer is preferably 0.1 ⁇ m or more. Moreover, it is preferable to set it as 3.0 micrometers or less. This is because if the thickness of the compound layer exceeds 3.0 ⁇ m, the compound layer becomes brittle and the coating adhesion may be lowered. More preferably, the thickness of the compound layer is in the range of 0.4 to 2.0 ⁇ m.
- Si-containing compound for example, silicone resin, lithium silicate, sodium silicate, colloidal silica, silane coupling agent and the like can be applied.
- Ti-containing compound for example, a titanate such as lithium titanate or calcium titanate, a titanium coupling agent mainly containing a titanium alkoxide or a chelate-type titanium compound can be applied.
- Al-containing compound for example, an aluminate such as sodium aluminate or calcium aluminate, an aluminum coupling agent mainly composed of an aluminum alkoxide or a chelate-type aluminum compound can be applied.
- a zirconate salt such as lithium zirconate or calcium zirconate
- a zirconium coupling agent mainly composed of a zirconium alkoxide or a chelate-type zirconium compound can be applied.
- At least one compound selected from the above-mentioned Si-containing compound, Ti-containing compound, Al-containing compound, and Zr-containing compound was deposited on the plating layer. Then, it may be heat-dried without washing with water.
- the adhesion treatment of these compounds may be any of a coating method, a dipping method, and a spray method, and a roll coater, a squeeze coater, a die coater or the like may be used. At this time, it is also possible to adjust the coating amount, make the appearance uniform, and make the thickness uniform by an air knife method or roll drawing method after the coating treatment, dipping treatment, and spraying treatment with a squeeze coater or the like. Heat drying may be performed within the range of 40 to 200 ° C., preferably 60 to 160 ° C., when the maximum temperature of the steel sheet is reached.
- a method of forming the compound layer on the plating layer is not limited to the above method.
- an acidic aqueous solution containing at least one cation selected from Si, Ti, Al, and Zr, and containing at least one anion selected from phosphate ion, fluoric acid ion, and fluoride ion can be formed on the plating layer by a method of immersing a steel sheet having a plating layer and then drying by heating without washing with water.
- the above compound layer can contain an inorganic solid lubricant. This is because by including an inorganic solid lubricant, the dynamic friction coefficient during hot pressing can be reduced and press workability can be improved.
- inorganic solid lubricants include metal sulfides (such as molybdenum disulfide and tungsten disulfide), selenium compounds (such as molybdenum selenide and tungsten selenide), graphite, fluorides (such as graphite fluoride and calcium fluoride), At least one selected from nitrides (boron nitride, silicon nitride, etc.), borax, mica, metal tin, alkali metal sulfates (sodium sulfate, potassium sulfate, etc.) can be applied.
- the content of the inorganic solid lubricant in the compound layer is preferably 0.1 to 20% by mass. This is because if the content is 0.1% by mass or more, a lubricating effect is obtained, and if the content is 20% by mass or less, the paint adhesion does not decrease.
- C 0.15-0.5% C is an element that improves the strength of steel. In order to increase the TS of a hot-pressed member to 980 MPa or more, the amount needs to be 0.15% or more. On the other hand, if the amount of C exceeds 0.5%, the blanking workability of the steel plate as the material will be significantly reduced. Therefore, the C content is 0.15 to 0.5%.
- Si 0.05-2.0% Si, like C, is an element that improves the strength of steel.
- the amount needs to be 0.05% or more.
- the Si content exceeds 2.0%, the occurrence of surface defects called red scales during hot rolling is remarkably increased, the rolling load is increased, and the ductility of the hot-rolled steel sheet is deteriorated.
- the Si content exceeds 2.0%, the plating processability may be adversely affected when a plating process for forming a plating film mainly composed of Zn or Al on the surface of the steel sheet is performed. Therefore, the Si content is 0.05 to 2.0%.
- Mn 0.5-3% Mn is suppressed ferrite transformation is an effective element for improving the hardenability, and since lowering the Ac 3 transformation point, in element effective to lower the heating temperature before hot pressing is there. In order to exhibit such an effect, the amount needs to be 0.5% or more. On the other hand, if the amount of Mn exceeds 3%, Mn is segregated and the uniformity of the characteristics of the steel plate and hot pressed member is reduced. Therefore, the Mn content is 0.5 to 3%.
- P 0.1% or less
- the amount of P exceeds 0.1%, P is segregated and the uniformity of the characteristics of the steel plate and the hot pressed member is reduced, and the toughness is also significantly reduced. Therefore, the P content is 0.1% or less.
- Al 0.1% or less When the Al content exceeds 0.1%, blanking workability and hardenability of the steel sheet as raw material are lowered. Therefore, the Al content is 0.1% or less.
- N 0.01% or less
- the N amount exceeds 0.01%, nitrides such as AlN are formed during hot rolling or heating before hot pressing, and blanking workability and hardenability of the steel sheet as raw material are lowered. Therefore, the N content is 0.01% or less.
- the balance of the above components of the base steel plate is Fe and inevitable impurities, but for the following reasons, at least one selected from Cr: 0.01 to 1%, Ti: 0.2% or less, B: 0.0005 to 0.08% , Sb: 0.003 to 0.03% is preferably contained individually or simultaneously.
- Cr 0.01-1% Cr is an element effective for strengthening steel and improving hardenability. In order to exhibit such an effect, the Cr content is preferably 0.01% or more. On the other hand, if the Cr content exceeds 1%, the cost is significantly increased. Therefore, the upper limit of the Cr content is preferably 1%.
- Ti 0.2% or less Ti is an element effective for strengthening steel and improving toughness by refining crystal grains. It is also an element effective for forming a nitride in preference to B, which will be described next, and exhibiting the effect of improving hardenability by solid solution B. However, if the Ti content exceeds 0.2%, the rolling load during hot rolling increases extremely, and the toughness of the hot pressed member decreases, so the upper limit of the Ti content is preferably 0.2%.

- B is an element effective for improving the hardenability during hot pressing and toughness after hot pressing.
- the B content is preferably 0.0005% or more.

- Sb 0.003-0.03%
- Sb has an effect of suppressing a decarburized layer generated in the steel sheet surface layer portion between the time when the steel plate is heated before hot pressing and the time when the steel plate is cooled by a series of processes of hot pressing. In order to exhibit such an effect, the amount needs to be 0.003% or more. On the other hand, if the Sb content exceeds 0.03%, the rolling load increases and the productivity decreases. Therefore, the Sb amount is preferably 0.003 to 0.03%.
- the above-described hot press steel sheet of the present invention is hot pressed after heating in the temperature range of Ac 3 transformation point to 1000 ° C. to become a hot press member.
- the reason for heating above the Ac 3 transformation point before hot pressing is to form a hard phase such as a martensite phase by rapid cooling during hot pressing, thereby increasing the strength of the member.
- the upper limit of the heating temperature is set to 1000 ° C. because a large amount of ZnO is generated on the surface of the plating layer when the heating temperature exceeds 1000 ° C.

- the average heating rate during heating before hot pressing is not particularly limited, but for example, 2 to 200 ° C./s is preferable.
- the generation of ZnO on the surface of the plating layer and the generation of local scale in the defective portion of the plating layer increase as the high-temperature residence time during which the steel sheet is exposed to high-temperature conditions increases. For this reason, the faster the average temperature rise rate, the more preferable it is because the generation of scale can be suppressed.
- the holding time at the maximum temperature of the steel sheet is not particularly limited, but it is preferable to make it short for the same reason as described above, preferably 300 s or less, more preferably 120 s or less, and still more preferably. 10s or less.

Abstract
Description
(2)スケールやZnOの生成は、融点が700℃未満の低いZn系めっき層で起きやすい。
(3)スケールやZnOの生成を抑制するには、融点が高い10~25質量%のNiを含み、残部がZnおよび不可避的不純物からなるめっき層とすることが効果的である。
(1-1)めっき層
本発明では、熱間プレス時にスケールやZnOの生成を抑制するために、鋼板表面に10~25質量%のNiを含み、残部がZnおよび不可避的不純物からなるめっき層を設ける。めっき層のNi含有率を10~25質量%とすることにより、Ni2Zn11、NiZn3、Ni5Zn21のいずれかの結晶構造を有し、融点が881℃と高いγ相が形成されるので、加熱時におけるスケールやZnOの生成を最小限に抑制することができる。また、加熱時にはZn-Fe金属化合物が形成されないため、クラックの発生に伴うスケールの生成も抑制される。さらに、このような組成のめっき層は、熱間プレス完了後にもγ相として残存するため、Znの犠牲防食効果により優れた耐食性を発揮する。なお、Ni含有率が10~25質量%におけるγ相の形成は、Ni-Zn合金の平衡状態図とは必ずしも一致しない。これは、電気めっき法などで行われるめっき層の形成反応が非平衡で進行するためと考えられる。Ni2Zn11、NiZn3、Ni5Zn21のγ相は、X線回折法やTEM(Transmission Electron Microscopy)を用いた電子線回折法により確認できる。また、めっき層のNi含有率を10~25質量%とすることにより上述のとおりγ相が形成されるが、電気めっきの条件等によっては多少のη相が混在することがある。このとき、加熱時におけるスケールやZnOの生成を最小限に抑制するために、η相含有率は5質量%以下であることが好ましい。η相含有率は、めっき層の全重量に対するη相の重量比で定義され、例えばアノード溶解法などにより定量することができる。
980MPa以上の強度(TS)を有する熱間プレス部材を得るためには、めっき層の下地鋼板として、例えば、質量%で、C:0.15~0.5%、Si:0.05~2.0%、Mn:0.5~3%、P:0.1%以下、S:0.05%以下、Al:0.1%以下、N:0.01%以下を含有し、残部がFeおよび不可避的不純物からなる成分組成を有する熱延鋼板や冷延鋼板を用いることができる。各成分元素の含有量を限定する理由を、以下に説明する。ここで、成分の含有量を表す「%」は、特に断らない限り「質量%」を意味する。
Cは、鋼の強度を向上させる元素であり、熱間プレス部材のTSを980MPa以上にするには、その量を0.15%以上とする必要がある。一方、C量が0.5%を超えると、素材の鋼板のブランキング加工性が著しく低下する。したがって、C量は0.15~0.5%とする。
Siは、C同様、鋼の強度を向上させる元素であり、熱間プレス部材のTSを980MPa以上にするためには、その量を0.05%以上とする必要がある。一方、Si量が2.0%を超えると、熱間圧延時に赤スケールと呼ばれる表面欠陥の発生が著しく増大するとともに、圧延荷重が増大したり、熱延鋼板の延性の劣化を招いたりする。さらに、Si量が2.0%を超えると、ZnやAlを主体としためっき皮膜を鋼板の表面に形成するめっき処理を施す際に、めっき処理性に悪影響を及ぼす場合がある。したがって、Si量は0.05~2.0%とする。
Mnは、フェライト変態を抑制して焼入れ性を向上させるのに効果的な元素であり、また、Ac3変態点を低下させるので、熱間プレス前の加熱温度を低下するにも有効な元素である。このような効果の発現のためには、その量を0.5%以上とする必要がある。一方、Mn量が3%を超えると、Mnが偏析して素材の鋼板および熱間プレス部材の特性の均一性が低下する。したがって、Mn量は0.5~3%とする。
P量が0.1%を超えると、Pが偏析して素材の鋼板および熱間プレス部材の特性の均一性が低下するとともに、靭性も著しく低下する。したがって、P量は0.1%以下とする。
S量が0.05%を超えると、熱間プレス部材の靭性が低下する。したがって、S量は0.05%以下とする。
Al量が0.1%を超えると、素材の鋼板のブランキング加工性や焼入れ性が低下する。したがって、Al量は0.1%以下とする。
N量が0.01%を超えると、熱間圧延時や熱間プレス前の加熱時にAlN等の窒化物が形成され、素材の鋼板のブランキング加工性や焼入れ性が低下する。したがって、N量は0.01%以下とする。
Crは、鋼を強化するとともに、焼入れ性を向上させるのに有効な元素である。このような効果の発現のためには、Cr量を0.01%以上とすることが好ましい。一方、Cr量が1%を超えると、著しいコスト高を招くため、Cr量の上限は1%とすることが好ましい。
Tiは、鋼を強化するとともに、結晶粒の細粒化により靭性を向上させるのに有効な元素である。また、次に述べるBよりも優先して窒化物を形成して、固溶したBによる焼入れ性の向上効果を発揮させるのに有効な元素でもある。しかし、Ti量が0.2%を超えると、熱間圧延時の圧延荷重が極端に増大し、また、熱間プレス部材の靭性が低下するので、Ti量の上限は0.2%とすることが好ましい。
Bは、熱間プレス時の焼入れ性や熱間プレス後の靭性向上に有効な元素である。このような効果の発現のためには、B量を0.0005%以上とすることが好ましい。一方、B量が0.08%を超えると、熱間圧延時の圧延荷重が極端に増大し、また、熱間圧延後にマルテンサイト相やベイナイト相が生じて鋼板の割れなどが生じるので、B量の上限は0.08%とすることが好ましい。
Sbは、熱間プレス前に鋼板を加熱してから熱間プレスの一連の処理によって鋼板を冷却するまでの間に鋼板表層部に生じる脱炭層を抑制する効果を有する。このような効果の発現のためにはその量を0.003%以上とする必要がある。一方、Sb量が0.03%を超えると、圧延荷重の増大を招き、生産性を低下させる。したがって、Sb量は0.003~0.03%とすることが好ましい。
上記した本発明の熱間プレス用鋼板は、Ac3変態点~1000℃の温度範囲に加熱後に熱間プレスされて熱間プレス部材となる。熱間プレス前にAc3変態点以上に加熱するのは、熱間プレス時の急冷でマルテンサイト相などの硬質相を形成し、部材の高強度化を図るためである。また、加熱温度の上限を1000℃としたのは、加熱温度が1000℃を超えるとめっき層表面に多量のZnOが生成されるためである。なお、ここでいう加熱温度とは鋼板の最高到達温度のことをいう。
下地鋼板として、質量%で、C:0.23%、Si:0.25%、Mn:1.2%、P:0.01%、S:0.01%、Al:0.03%、N:0.005%、Cr:0.2%、Ti:0.02%、B:0.0022%、Sb:0.008%を含有し、残部がFeおよび不可避的不純物からなる成分組成を有し、Ac3変態点が820℃で、板厚1.6mmの冷延鋼板を用いた。この冷延鋼板の表面に、200g/Lの硫酸ニッケル六水和物および10~100g/Lの硫酸亜鉛七水和物を含有するpH1.5、温度50℃のめっき浴中で電流密度を5~100A/dm2と変化させて電気めっき処理を施して、表1に示すように、Ni含有率(残部はZnおよび不可避的不純物)、付着量、およびη相含有率の異なるめっき層を有する鋼板No.1~19を作製した。また、比較のために、上記冷延鋼板に溶融めっき処理を施した溶融Znめっき鋼板(GI)、合金化溶融Znめっき鋼板(GA)、溶融Zn-5%Alめっき鋼板(GF)、溶融Zn-55%Alめっき鋼板(GL)、めっき層のない冷延鋼板のままの鋼板No.20~24を作製した。表1に、このようにして作製された鋼板No.1~24を示す。
