High Mn with low cracking susceptibility
The main topic is non-magnetic steel.
以下本発明の成分限定について詳細に説明する。The ingredient limitations of the present invention will be explained in detail below.
Ｃニオ−ステナイト安定化元素で、非磁性化に極めて有
効な元素である。それとともに、強度を上げる働きをも
つ。そのためには、０．３０％以上を含有させる必要が
ある。しかし、０．７５％を越えて含有すると熱間加工
性を劣化して熱間圧延が不可能になる。C is a niostenite stabilizing element and is an extremely effective element for making it non-magnetic. At the same time, it also works to increase strength. For that purpose, it is necessary to contain 0.30% or more. However, if the content exceeds 0.75%, hot workability deteriorates and hot rolling becomes impossible.
Ｓ■ ：高強度化には有効な元素であるか、多量の含有
は非磁性化に不利である。したがって、０．０５〜２．
０％とした。S■: Is it an effective element for increasing strength, but its inclusion in a large amount is disadvantageous for making it non-magnetic. Therefore, 0.05-2.
It was set to 0%.
Ｍｎ：オーステナイト安定化元素で、非磁性化に極めて
有効な元素として、１４％以上を含有させる。しかし、
２０％を越えて含有するのは合金コストによる製造コス
トをいたずらに高くするだけである。Mn: An austenite stabilizing element that is extremely effective in making it non-magnetic, and is contained in an amount of 14% or more. but,
Containing more than 20% only unnecessarily increases manufacturing costs due to alloy costs.
Ｎｉ ニオ−ステナイト安定化元素で、非磁性化および
靭性向上に極めて有効な元素であるため、できるだけ含
有することが望ましいか、多量の含有は合金コストによ
る製造コストアップとなるため３ 、 Ｄ ９ｔ５以下
とした。Ni is a niostenite stabilizing element and is an extremely effective element for making it non-magnetic and improving toughness, so it is desirable to contain it as much as possible, or because containing a large amount increases manufacturing costs due to alloy costs, 3, D 9t5 or less And so.
Ｃｕ：この元素の添加により応力腐食割れ感受性を低下

の効果が小さく、また３、０％を越えると効果が減少す
る傾向にある。従ってＣｕ含有量は０．１〜３．０％に
限定した。Cu: This element is an effective component that reduces stress corrosion cracking susceptibility by adding this element.If the amount is less than 0.1%, the effect is small, and if it exceeds 3.0%, the effect tends to decrease. Therefore, the Cu content was limited to 0.1 to 3.0%.
Ｎニオ−ステナイト安定化元素で、非磁性化に極めて有
効な元素である。また、強度を上げるのに著しい働きを
もつ。そのためには、少なくとも０．０１０％以上含有
していなければならない。しかし、０．２０％を越える
添加は著しく靭性を損なう。N is a stabilizing element for niostenite and is an extremely effective element for making it non-magnetic. It also has a remarkable effect on increasing strength. For this purpose, the content must be at least 0.010% or more. However, addition of more than 0.20% significantly impairs toughness.
Ｎｂ：０．０１％以上含有することにより製品の組織を
細粒化し耐力を上げる。しかし、多量の含有は熱間加工
性の低下を招くので０．２０％以下とした。Nb: By containing 0.01% or more, the structure of the product becomes finer and the yield strength is increased. However, since a large amount of content leads to a decrease in hot workability, the content is set to 0.20% or less.
不純物元素として、Ｓは靭性を低下さすために少ない方
がよく、０．０５％以下が望ましい。また、Ｐも靭性を
下げるためにその含有量は少ないことが必要で、０．０
４０％以下が望ましい。上記のような成分組成を含有し
た残部が鉄および不可避的不純物からなる鋼は、応力腐
食割れ感受性の小さい高Ｍｎ非磁性鋼となる。As an impurity element, it is better to have a small amount of S because it reduces toughness, and preferably 0.05% or less. In addition, in order to lower the toughness, the content of P must be small, and 0.0
40% or less is desirable. Steel containing the above-mentioned composition with the remainder consisting of iron and unavoidable impurities becomes a high-Mn nonmagnetic steel with low stress corrosion cracking susceptibility.
さらに本発明は、上記のような成分組成の高Ｍｎ非磁性
鋼の強度や加工性を向上させるために、Ｎｂ、Ｖ、Ｔｉ
の少量を選択的に含有させることができる。Furthermore, in order to improve the strength and workability of high-Mn nonmagnetic steel having the above-mentioned composition, the present invention
may optionally be included in small amounts.
Ｔｊ：Ｎｂと同様に鋼の耐力の向上と熱間加工性の劣化
を配慮してその含有量を０，０１〜０，２０％と限定し
た。Tj: Like Nb, its content was limited to 0.01 to 0.20% in consideration of improving the yield strength of steel and deteriorating hot workability.
Ｖ：細粒化および微細析出物形成により強度を上げる。V: Strength is increased by grain refinement and formation of fine precipitates.
そのためには０．０１％以上の含有が必要である。しか
し、多量の含有は合金コストによる製造コストアップと
なるため２．０％以下とした。For this purpose, the content must be 0.01% or more. However, since a large amount of content increases manufacturing costs due to alloy costs, it is set at 2.0% or less.
上記のような成分組成をさらに含有した鋼は、応力腐食
割れ感受性が小さく、しかも高強度で熱間加工性のすぐ
れた高Ｍｎ非磁性鋼を提供することができる。A steel further containing the above-mentioned composition can provide a high-Mn nonmagnetic steel with low stress corrosion cracking susceptibility, high strength, and excellent hot workability.
また、本発明においては特に限定するものではないが、
Ｃｒの２％以下の含有は鋼の非磁性化を安定にし、また
ＡΩとＣａを各々０，２０％以下と０．０２％以下含有
させることは鋼の清浄度を上げ靭性および熱間加工性を
向上させるのに白“効である。In addition, although the present invention is not particularly limited,
Containing Cr of 2% or less stabilizes the demagnetization of the steel, and containing AΩ and Ca of 0.20% or less and 0.02% or less, respectively, increases the cleanliness of the steel and improves toughness and hot workability. White is effective in improving

すなわち、電気炉または転炉で溶製し、連続鋳造によっ
てスラブとするか、−旦造塊作業によって鋼塊とした後
分塊圧延によってスラブとする。That is, the steel is melted in an electric furnace or a converter and then made into a slab by continuous casting, or the steel is made into a steel ingot by an ingot operation and then made into a slab by blooming.
