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。
The microstructure and properties of powder forged steels 12Cr2Ni4A and 18Cr2Ni4WA were discussed. Forged steel 12Cr2Ni4A with oxygen content less than 0.2%, carbon content 0.08 ~ 0.12%, and 18Cr2Ni4WA powder forged steel with carbon content of 0.11 ~ 0.16% have good mechanical properties. Prolonged diffusion annealing can effectively improve the toughness of powder forged steel.
