摘要： Austenitic stainless steel essentially consisting of 1.0-2.5 wt. percent Si, 1.5-5.0 wt. percent Mn, 1.0-4.0 wt. percent Cu, 6.09.0 wt. percent Ni, 15.0-19.0 wt. percent Cr, not more than 0.06 wt. percent C, nor more than 0.03 wt. percent N, and balance Fe and incidental impurities, in which the total content of C and N in the solid solution state is less than 0.04 wt. percent has excellent drawability and stretchability and is highly resistant to delayed cracking. Although the austenite phase of this steel is unstable to strain-induced martensitic transformation, the steel is highly resistant to delayed cracking. The said low content of C and N in the solid solution state is achieved by known decarbonization processes or by addition of a limited amount of Al and/or Ti to the melt.
摘要翻译：奥氏体不锈钢基本上由1.0-2.5重量％百分比的Si，1.5-5.0重量％ Mn为1.0-4.0重量％％Cu，6.0-9.0wt。％，15.0-19.0重量％％Cr，不大于0.06wt。百分比C，也不超过0.03重量％ N，并且平衡Fe和杂质，其中固溶体状态下C和N的总含量小于0.04wt。百分比具有优异的可拉伸性和拉伸性，并且对延迟开裂具有高度抗性。虽然这种钢的奥氏体相对于应变诱导的马氏体相变不稳定，但是钢对延迟裂纹具有很高的抗性。通过已知的脱碳工艺或通过向熔体中加入有限量的Al和/或Ti来实现固溶体状态下所述低含量的C和N。

摘要： In the conventional process of manufacturing sheets of metastable austenitic stainless steel, a mechanical polishing step is included before or after the final temper rolling step. By insertion of this step, the fatigue resistance of the produced steel strips and sheets is remarkably improved.

摘要： A newly proposed steel consists of 8.0-35.0wt.% Cr, 0.05-1.20wt.% C, 0.05-3.0wt.% at least one of Ti, Nb, Zr, V and W and the balance being essentially Fe and has the structure that a total amount of Ti, Nb, Zr V and/or W carbide precipitations distributed in a steel matrix is adjusted to 0.1wt.% or more. The steel is bestowed with excellent abrasion-resistance by distribution of carbide precipitations. These carbides have nearly the same hardness as hard particles such as alumina and silicon carbides which causes abrasive abrasion. Due to such excellent abrasion-resistance, a weaving machine member, a sewing needle, an agricultural machine member such as a mowing tooth or a cutter blade made of the steel can be used over a long period of time.
