摘要
讨论了粉末锻造钢１２Ｃｒ２Ｎｉ４Ａ和１８Ｃｒ２Ｎｉ４ＷＡ的组织与性能。氧含量低于０．２％，碳含量为０．０８～０．１２％的粉末锻造钢１２Ｃｒ２Ｎｉ４Ａ和碳含量为０．１１～０．１６％的粉末锻造钢１８Ｃｒ２Ｎｉ４ＷＡ有较好的力学性能。长时间扩散退火可有效地提高粉末锻造钢的韧性。
Microstructure and mechanical properties of powder forging steel 12Cr2Ni4A and 18Cr2Ni4WA are described in this paper. Forging powder steel 12Cr2Ni4A with 0.08～0.12%C and less than 0.2% O2,18Cr2Ni4WA with 0.11～0.16% C have better mechanical properties. Toughness of powder forging steel can be increased efficiently by diffusion annealing in longer time.
