磁性鋼が強く望まれている。The steel used in these products is required to have excellent rust resistance as well as wear resistance, and austenitic stainless steel and high Mn and low CrwI are generally used as non-magnetic steels. Mn-low Cr1q has superior characteristics such as higher strength than austenitic stainless steel, stable non-magnetic properties even after strong cold-opening, and low cost6. High Mn, low Cr steel has the problem of rusting easily in a humid environment, and when used in the above-mentioned light electrical technology field, this rust deteriorates non-magnetic properties and increases frictional resistance. (High Mn non-magnetic steel with excellent rust resistance is strongly desired.)

As a result of extensive experimental research and detailed examination of the effects of contained components and component ratios, we have found that rusting can be improved by increasing the content of Cr, Cu, Mo, etc. in steel, and that rusting can be improved by increasing the content of Cr, Cu, Mo, etc. It was discovered that even steel containing a large amount of elements is incomplete, and if the inclusions in the steel are large or numerous, rust will occur from the inclusions as a starting point through hole line or crevice corrosion. The company developed a high-strength non-magnetic steel.

本発明に係る耐銹性の優れた高強度非磁性鋼について以
下詳細に説明する。The high-strength nonmagnetic steel with excellent rust resistance according to the present invention will be described in detail below.
先ず、本発明に係る耐銹性の優れた高強度非磁性鋼の含
有成分および成分割合について説明する。First, the components and component ratios of the high-strength nonmagnetic steel with excellent rust resistance according to the present invention will be explained.
Ｃは極めて優れたオーステナイト形成元素であり、かつ
、強度を付与する元素であり、含有量が０．０ｂｗｔ％
未満では非磁性が安定せず、また、０．１５ｗｔ％を越
えて含有されると耐銹性が劣化するようになる。よって
、Ｃ含有量は０．１０〜０．１５＋ｌｌｔ％とする：
Ｓｉは脱酸剤として必要であり、含有量が０．０５ｗｔ
％未満では脱酸効果が不足し、また、０．６０ｗｔ％を
越えて含有されるとＳｉの酸化物がＢ系介在物として析
出し、耐銹性を劣化させる。よって、Ｓｉｔ有量ハ０．
０５−０．６０ｗｔ％トｔ ７１゜Ｍｎはオーステナイ
ト形成元素であり、含有量が１６ｗｔ％未満ではこの効
果は不充分であり、また、２５ｗｔ％を越えて含有され
ると熱間加工性が着しく劣化する。よって、Ｍｎ含有量
は１６〜２５ｗｔ％とする。C is an extremely excellent austenite-forming element and an element that imparts strength, and the content is 0.0 bwt%.
If the content is less than 0.15 wt%, the non-magnetism will not be stable, and if the content exceeds 0.15 wt%, the rust resistance will deteriorate. Therefore, the C content is set to 0.10 to 0.15+llt%: Si is necessary as a deoxidizing agent, and the content is 0.05 wt%.
If the content is less than 0.60 wt%, the deoxidizing effect will be insufficient, and if the content exceeds 0.60 wt%, Si oxides will precipitate as B-based inclusions, degrading rust resistance. Therefore, Sit quantity is 0.
05-0.60wt% 71゜Mn is an austenite-forming element, and if the content is less than 16wt%, this effect is insufficient, and if the content exceeds 25wt%, hot workability deteriorates. deteriorates rapidly. Therefore, the Mn content is set to 16 to 25 wt%.
Ｓは本発明に係る耐銹性の優れた高強度非磁性鋼に重大
な影響を与える元素であり、即ち、多量のＭｎを含有す
る鋼の場合にはＭｎＳを析出し易く、このＭｎＳは水溶
液中に溶出して耐銹性を劣化させるのにつながる孔線の
起点となる。よって、Ｓ含有量はその上限を０．０１０
ｗｔ％とする。S is an element that has a significant effect on the high-strength nonmagnetic steel with excellent rust resistance according to the present invention. In other words, in the case of steel containing a large amount of Mn, MnS is likely to precipitate, and this MnS is easily deposited in an aqueous solution. This becomes the starting point for pore lines that elute into the surface and deteriorate rust resistance. Therefore, the upper limit of the S content is 0.010
Let it be wt%.
ＮｉはＣ，Ｍｎ、後述するＮと同様にオーステナイト形
成元素であり、溶製に際して問題となるＮ含有量を減少
させることができるが、多量の含有は価格が高くなって
不経済である。よって、Ｎｉ含有量はその上限を４．０
ｗｔ％とする。Ni is an austenite-forming element like C, Mn, and N (described later), and can reduce the N content, which is a problem during melting, but containing a large amount increases the price and is uneconomical. Therefore, the upper limit of Ni content is 4.0
Let it be wt%.
Ｃｒは非磁性を安定化させ、かつ、耐銹性を付与する顕
著な効果があり、そして、耐銹性を満足させるためには
Ｃｒ含有量は１０ＩＩＩｔ％以上で充分であるが、含有
量が１４ｗｔ％未満ではマルテンサイト相の生成に上り
非磁性が不完全となり、また、２０ｗｔ％を越えて含有
されるとフェライト相の生成により非磁性が不安定とな
る。よって、Ｃｒ含有量は１４〜２０ｗｔ％とする。Cr has a remarkable effect of stabilizing non-magnetism and imparting rust resistance, and a Cr content of 10IIIt% or more is sufficient to satisfy the rust resistance. If the content is less than 14 wt%, a martensitic phase will be formed, resulting in incomplete nonmagnetism, and if the content exceeds 20 wt%, a ferrite phase will be formed, resulting in unstable nonmagnetism. Therefore, the Cr content is set to 14 to 20 wt%.
Ｎ１ＩＣと同様に極めて有効なオーステナイト形成元素
であり、かつ、鋼の強度を付与するのに有効な元素であ
り、含有量が０．３ｗｔ％未満ではこのような効果は不
充分であり、また、大気中で溶製する場合は０．６ｗｔ
％を越えて含有されるど鋳塊に気泡が生じ易く、かつ、
熱間加工性を著しく劣化させる。よって、Ｎ含有量は０
．３〜０．６ｗｔ％とする。Like N1IC, it is an extremely effective austenite-forming element and an effective element for imparting strength to steel, and if the content is less than 0.3 wt%, this effect is insufficient, and 0.6wt when melting in the atmosphere
If the content exceeds %, air bubbles are likely to occur in the ingot, and
Significantly deteriorates hot workability. Therefore, the N content is 0
．． 3 to 0.6 wt%.
０は本発明に係る耐銹性の優れた高強度非磁性鋼に重大
な影響を与える元素であり、即ち、含有量が０．０ＩＩ
ｗｔ％を越えて含有されると、ｌの非金属介在物が多く
なり、かつ、巨大な介在物が生成し易くなり、そして、
Ｂ系介在物は冷間加工を行なった場合、Ｂ系介在物自体
に割れが発生したり、或いは、マトリックスとの開にボ
イドを生成し易く、これが隙間腐蝕の起点となって耐銹
性を劣化させる。よって、Ｏ含有量はその上限を帆０１
ｗｔ％とする。0 is an element that has a significant effect on the high-strength nonmagnetic steel with excellent rust resistance according to the present invention, that is, the content is 0.0II.
When the content exceeds wt%, the number of nonmetallic inclusions increases, and giant inclusions are likely to be generated, and
When B-based inclusions are subjected to cold working, they tend to crack or form voids between them and the matrix, which becomes the starting point for crevice corrosion and impairs rust resistance. deteriorate. Therefore, the O content has an upper limit of 01
Let it be wt%.
Ａ１は重要な元素であり、脱酸剤として必要であり、か
つ、Ｂ系介在物の析出量を抑制して耐銹性を向上させる
のに有効な元素であり、さらに、オーステナイト粒を微
細化して強度を高める元素であり、含有量が０．００１
ｗｔ％未満では脱酸効果が不足し、また、０．２０ｗｔ
％を越えて含有されると靭性を低下させる。よって、Ａ
ｌ含有量は０．００１〜０゜２０ｗｔ％とする。A1 is an important element, necessary as a deoxidizing agent, and effective for suppressing the amount of precipitation of B-based inclusions and improving rust resistance. It is an element that increases strength, and the content is 0.001
If it is less than 0.20 wt%, the deoxidizing effect is insufficient, and if it is less than 0.20 wt%, the deoxidizing effect is insufficient.
If the content exceeds %, the toughness will decrease. Therefore, A
The l content is 0.001 to 0.20 wt%.
Ｃｕはオーステナイト形成元素であり、また、耐銹性を
高くする効果があり、含有量が０．１ｕｓｔ％未満では
期待する効果は得られず、また、４．ＯＷＬ％を越えて
含有されると熱間加工性を劣化させる。Cu is an austenite-forming element and has the effect of increasing rust resistance, but if the content is less than 0.1 ust%, the expected effect cannot be obtained; If the content exceeds OWL%, hot workability will deteriorate.
よって、Ｃｕ含有量はＯＪ〜４．０ｗｔ％とする。Therefore, the Cu content is OJ~4.0 wt%.
Ｍｏは耐蝕性および強度を改善するのに有効な元素であ
り、含有量が０．ｂｗｔ％未満では顕著な効果が期待で
きず、また、３．０ｗｔ％を越えて含有されるとフェラ
イトを生成して非磁性が不安定となり、Ｍｏは高価なた
め経済的に不利である。よって、Ｍｏ含有量は０．１−
３．０ｗｔ％とする。Mo is an effective element for improving corrosion resistance and strength, and when the content is 0. If it is less than bwt%, no significant effect can be expected, and if it is contained in an amount exceeding 3.0wt%, ferrite will be produced and non-magnetic properties will become unstable, and Mo is expensive, which is economically disadvantageous. Therefore, the Mo content is 0.1-
It is set to 3.0wt%.
Ｖ、Ｔｉ、Ｎｂ、Ｗ、Ｚｒは結晶粒度を微細化し、強度
の向上に有効で、かつ、結晶粒界のＣｒ欠乏層生成原因
となるＣｒ炭化物の析出を抑制し、耐銹性の改善に有効

、Ｎｂ、Ｗ、Ｚｒはこのうちから選んだ１種または２種
以上の含有量をｏ、 ｏｏｓ〜１．０１％とする。V, Ti, Nb, W, and Zr refine the grain size and are effective in improving strength. They also suppress the precipitation of Cr carbide, which causes the formation of Cr-deficient layers at grain boundaries, and improve rust resistance. It is an effective element, and if the content of one or more selected from these elements is less than 0.005 wt%, the strength cannot be sufficiently improved, and if the content exceeds 1.0 wt%. If it is contained, the toughness will decrease. Therefore, V, Ti
, Nb, W, and Zr, the content of one or more selected from these is set to o, oos to 1.01%.

よって、非金属介在物の含有量は面積率で６０．１０％
とする。Therefore, the content of nonmetallic inclusions is 60.10% in terms of area ratio.
