ものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a solder-plated stainless steel sheet for exterior building materials that can obtain high joining strength by resistance welding and does not generate intergranular corrosion even when used outdoors for a long period of time. Things.
〈従来技術とその課題〉 最近、建築物の屋根材や外壁用材として“ステンレス
鋼板にハンダめっきした材料”の適用例が増えてきつつ
ある。<Prior art and its problems> In recent years, examples of application of “a material obtained by solder plating a stainless steel plate” as a roof material for a building or a material for an outer wall are increasing.
この材料は、溶融したハンダ浴中にステンレス鋼板を

は、ハンダの犠牲陽極作用によりステンレス鋼基板の腐
食や発銹が防止されると言う長所も併せ持っていた。This material is usually manufactured by immersing a stainless steel plate in a molten solder bath and plating it.
When unused, the surface has a metallic luster, but when used as a roofing material, etc., if exposed to the air for a long time, the surface of the solder plating layer will corrode and have a dark gray calm appearance. This is what customers like from the standpoint of design. The solder-plated stainless steel plate also has an advantage that corrosion and rust of the stainless steel substrate are prevented by the sacrificial anode action of the solder.
ところで、従来のハンダめっきステンレス鋼板では、
ステンレス鋼基板として18Cr−8Niステンレス鋼（SUS30
4相当材）が用いられている。By the way, in the conventional solder-plated stainless steel sheet,
18Cr-8Ni stainless steel (SUS30
4 equivalent material) is used.

と粒界腐食が発生して溶接部が割れたり発銹したりする
ためであった。This is because, when a ferritic stainless steel such as 18Cr stainless steel (equivalent to SUS430) is used as a base material, when a resistance welding such as seam welding or spot welding is performed on the base material, the grain boundaries become sensitized ( This is because chromium carbide precipitation locally deteriorates the corrosion resistance), and when this is exposed outdoors, intergranular corrosion occurs and the welded portion is cracked or rusted.

ライト系ステンレス鋼等では発生しない。However, `` If the roof surface is formed while efficiently joining this solder-plated stainless steel sheet by seam welding etc., it will be possible to make a roof with extremely excellent waterproofness, and the design and corrosion resistance will be the same as conventional stainless steel roofs. The present inventors conducted a study on the resistance weldability of a solder-plated stainless steel sheet under the concept of `` excellent compared to the above. '' In the case of a plated stainless steel sheet, it has been found that when this is welded by resistance welding, solder tends to enter the crystal grain boundaries of the stainless steel and cause a decrease in bonding strength. Such a phenomenon is peculiar to austenitic stainless steel, and does not occur in ferritic stainless steel or the like.
従って、ハンダめっきステンレス鋼板が建材等として

As a result, (a) a substrate of a solder-plated stainless steel sheet for exterior building materials is made of “Cr stabilized with Nb or Ti” When made of stainless steel, it is possible to prevent the phenomenon that solder penetrates into the crystal grain boundary and lower the joining strength of the resistance welded part, and also the occurrence of intergranular corrosion due to long-term outdoor use can be suppressed as much as possible. (B) Moreover, it was found that by adjusting the solder constituting the plating layer to a specific composition, it is possible to effectively suppress color unevenness and corrosion resistance after exposure to the atmosphere.

"
以下、本発明外装建材用ハンダめっきステンレス鋼板
において“めっき層としてのハンダ”の化学組成並びに
ステンレス鋼基板の好適化学組成を前記の如くに定めた
理由を、各成分の作用と共に詳述する。Hereinafter, the reason why the chemical composition of “solder as a plating layer” and the preferable chemical composition of the stainless steel substrate in the solder-plated stainless steel sheet for exterior building materials of the present invention are determined as described above, together with the action of each component, will be described in detail.
〈作用〉 Ａ）ハンダの化学組成 こで言う“ハンダ”とはPdとSnを主成分とする合金で
あって、建築物の屋根や外壁用等の用途に供する場合に
は（75〜95）％Pb−（５〜25）％Snの化学組成のものが
適している。<Actions> A) Chemical composition of solder "Solder" is an alloy containing Pd and Sn as main components. When it is used for roofs and outer walls of buildings (75-95) Those having a chemical composition of% Pb- (5-25)% Sn are suitable.
なぜなら、〔Pb/Sn〕の比が95/5よりも大きいとメッ
キの付着性が悪くて大気暴露後の色ムラが大きくなり、
一方、〔Pb/Sn〕の比が75/25を下回るとハンダの耐食性
が悪くなって（溶出量が大となって）、コストも高くな
るからである。Because, if the ratio of [Pb / Sn] is larger than 95/5, the adhesion of the plating is poor, and the color unevenness after exposure to the atmosphere becomes large,
On the other hand, if the ratio [Pb / Sn] is less than 75/25, the corrosion resistance of the solder deteriorates (the amount of elution increases), and the cost increases.
Ｂ）ステンレス鋼基板の好適化学組成 Cr Cr含有量が10.00％未満では耐食・耐銹性が不十分で
あり、一方、25.00％を超えて含有させると硬質となっ
て成形性の劣化を招くようになる。従って、Cr含有量は
10.00〜25.00％と定めた。B) Suitable chemical composition of the stainless steel substrate Cr If the Cr content is less than 10.00%, the corrosion resistance and rust resistance are insufficient, while if it exceeds 25.00%, it becomes hard and deteriorates the formability. become. Therefore, the Cr content is
It was determined as 10.00-25.00%.
Si Siは脱酸のために必要な元素であるが、2.00％を超え
て含有させると成形性の劣化を招くようになる。従っ
て、Si含有量は2.00％以下と定めた。Si Si is an element necessary for deoxidation, but if it is contained in excess of 2.00%, the moldability will be deteriorated. Therefore, the Si content was determined to be 2.00% or less.
Mn Mnも脱酸のために必要な元素であるが、1.00％を超え
て含有させると成形性を悪化させるばかりか、耐食性の
劣化をも招くようになる。従って、Mn含有量は1.00％以
下と定めた。Mn Mn is also an element necessary for deoxidation. However, if it is contained in excess of 1.00%, not only the moldability is deteriorated, but also the corrosion resistance is deteriorated. Therefore, the Mn content is determined to be 1.00% or less.
Ｃ Ｃ含有量が0.06％を超えると耐食性や成形性に悪影響
が出てくる。従って、Ｃ含有量は0.06％以下と定めた。If the C content exceeds 0.06%, the corrosion resistance and moldability are adversely affected. Therefore, the C content is determined to be 0.06% or less.
Ｎ Ｎ含有量が0.06％を超えると耐食性や成形性に悪影響
が出てくる。従って、Ｎ含有量は0.06％以下と定めた。If the NN content exceeds 0.06%, the corrosion resistance and moldability are adversely affected. Therefore, the N content is determined to be 0.06% or less.
Nb,及びTi 〔Ｃ（％）＋Ｎ（％）〕×８〜1.00％， Nb又はTiはC,Nと優先的に化合物を形成し、耐食性に悪
影響を及ぼすCrの炭化物や窒化物の生成を防止する。こ
の現象を“安定化”と呼んでいるが、十分な安定化効果
を確保するためには、Nbによる場合はNb含有量を〔Ｃ
（％）＋Ｎ（％）〕の値の８倍以上に、またTiによる場
合はTi含有量を〔Ｃ（％）＋Ｎ（％）〕の値の４倍以上
にする必要があり、両者を複合添加する場合には式 を満足する添加量を確保する必要がある。Nb, and Ti [C (%) + N (%)] × 8 to 1.00%, Nb or Ti preferentially forms a compound with C and N to form carbides and nitrides of Cr that adversely affect corrosion resistance. To prevent. This phenomenon is called "stabilization." In order to secure a sufficient stabilizing effect, in the case of Nb, the Nb content is [C
(%) + N (%)], and when using Ti, the Ti content must be at least four times the value of [C (%) + N (%)]. When adding It is necessary to secure an addition amount satisfying the above.
一方、Nb含有量が1.00％を超えると成形性及び靭性に
悪影響が及ぶようになり、Ti含有量が0.80を超えても成
形性の劣化を招くようになる。On the other hand, if the Nb content exceeds 1.00%, the formability and toughness will be adversely affected, and if the Ti content exceeds 0.80, the moldability will deteriorate.
従って、Nbによって安定化する場合にはNb含有量は
〔Ｃ（％）＋Ｎ（％）〕×８〜1.00％と、またTiよって
安定化する場合にはTi含有量は〔Ｃ（％）＋Ｎ（％）〕
×４〜0.80％と、そしてNbとTiの両者によって安定化す
る場合には両者の合計含有量が であって、かつ Nb≦1.00％， Ti≦0.80％ なる条件を満たすことと定めた。Therefore, when stabilizing with Nb, the Nb content is [C (%) + N (%)] × 8 to 1.00%, and when stabilizing with Ti, the Ti content is [C (%) + N (%)]
× 4 to 0.80%, and when stabilized by both Nb and Ti, the total content of both And Nb ≦ 1.00%, Ti ≦ 0.80%.
Cu,Mo,及びNi これらはステンレス鋼基板の耐食性改善に有効な元素
であるため必要に応じて１種以上を含有させるのが望ま
しいが、各々の含有量の上限は次の理由によって定め
た。Since Cu, Mo, and Ni are effective elements for improving the corrosion resistance of the stainless steel substrate, it is desirable to include one or more of them as necessary. The upper limit of each content is determined for the following reasons.
Cu:Cu成分は耐食性及び成形性を改善する作用を有し
ているが、1.00％を超えて含有量させると熱間加工性が
悪化する。Cu: The Cu component has an effect of improving corrosion resistance and moldability, but if the content exceeds 1.00%, hot workability deteriorates.
Mo:Mo成分は耐食性を改善する作用を有しているが、
3.00％を超えて含有させると成形性の劣化を招く。Mo: Mo component has the effect of improving corrosion resistance,
When the content exceeds 3.00%, the moldability is deteriorated.
Ni:Ni成分は耐食性を改善する作用を有しているが、
1.00％を超えて含有させると成形性の劣化を招く。Ni: Ni component has the effect of improving corrosion resistance,
If the content exceeds 1.00%, the moldability is deteriorated.

や壁面等を作ることが可能となる。As described above, "Sn content: 5 to 25% solder" is plated on "Nb or Ti-stabilized ferritic (Cr-based) stainless steel sheet", preferably on the Cr-based stainless steel sheet having the specific chemical composition described above. The soldered stainless steel sheet for exterior building materials according to the present invention has high joining strength by resistance welding and hardly deteriorates the corrosion resistance and color unevenness of the welded portion. It is possible to make roofs and wall surfaces.

厚すぎると溶接が困難になる。従って、ハンダめっき層
の厚みは10μｍを超え50μｍ以下、望ましくは10μｍを
超え20μｍ以下程度とするのが良い。In the case of the solder-plated stainless steel sheet for exterior building materials, if the plating thickness is too thin, sufficient corrosion resistance and durability for exterior building materials cannot be secured. On the other hand, the greater the plating thickness, the better the corrosion resistance and durability, but if it is too thick, welding becomes difficult. Therefore, the thickness of the solder plating layer should be more than 10 μm and not more than 50 μm, preferably more than 10 μm and not more than 20 μm.
続いて、本発明の効果を実施例により更に具体的に説

確認された。Furthermore, plating with solder having a particularly high Pb ratio causes a lot of blackish color unevenness due to exposure to the air, which is not desirable in appearance.On the other hand, when the Sn ratio is high, solder elution is large and some stainless steel It was also confirmed that the substrate was exposed.
