高强度非磁性不锈钢、包含该不锈钢的部件及其制法
摘要：
本发明涉及一种高强度非磁性不锈钢，其包含以重量％计的以下元素：0.01％至0.06％的C、0.10％至0.50％的Si、20.5％至24.5％的Mn、0.040％或更低的P、0.010％或更低的S、3.1％至6.0％的Ni、0.10％至0.80％的Cu、20.5％至24.5％的Cr、0.10％至1.50％的Mo、0.0010％至0.0050％的B、0.010％或更低的O、0.65％至0.90％的N，并且其余为Fe和不可避免的杂质；所述钢符合下式(1)至(4)：[Cr]+3.3×[Mo]+16×[N]≥30(1)；{Ni}/{Cr}≥0.15(2)；2.0≤[Ni]/[Mo]≤30.0(3)；和[C]×1000/[Cr]≤2.5(4)，其中，[Cr]、[Mo]、[N]、[Ni]和[C]分别表示在所述钢中Cr的含量、Mo的含量、N的含量、Ni的含量和C的含量，并且{Ni}表示[Ni]、[Cu]和[N]之和、{Cr}表示[Cr]和[Mo]之和。本发明还涉及包含所述钢的高强度非磁性不锈钢部件及该高强度非磁性不锈钢部件的制造方法。
摘要（英）：

The present invention relates a high-strength nonmagnetic stainless steel, containing, by weight percent, 0.01 to 0.06% of C, 0.10 to 0.50% of Si, 20.5 to 24.5% of Mn, 0.040% or less of P, 0.010% or less of S, 3.1 to 6.0% of Ni, 0.10 to 0.80% of Cu, 20.5 to 24.5% of Cr, 0.10 to 1.50% of Mo, 0.0010 to 0.0050% ofB, 0.010% or less of O, 0.65 to 0.90% of N, and the remainder being Fe and inevitable impurities; the steel satisfying the following formulae (1) to (4): wherein [Cr], [Mo], [N], [Ni], [Mo] and [C] represent the content of Cr, the content of Mo, the content of N, the content of Ni, the content of Mo and the content of C in the steel, respectively, and {Ni} represents the sum of [Ni], [Cu] and [N], and {Cr} represents the sum of [Cr] and [Mo]. The present invention further relates toa high-strength nonmagnetic stainless steel part containing the steel and a process for producing the same.
