一、前言 马氏体时效不锈钢集中了马氏体时效钢和18—8不锈钢的优点,具有优良的综合性能一高强度、高塑性、高韧性和优良的耐腐蚀性。它取代18—8不锈钢制造耐蚀耐压管道和压力壳体时,不仅可以大大减轻重量,而且可以使设备更为安全可靠。马氏体时效不锈钢热处理工艺非常简单,制造大截面另件时,可以保证整个截面性能均匀。因此,近年来
I. Introduction Maraging stainless steel has the advantages of martensitic aging steel and 18-8 stainless steel, has excellent comprehensive performance of a high strength, high plasticity, high toughness and excellent corrosion resistance. It replaces 18-8 stainless steel corrosion resistance pipe and pressure housing, not only can greatly reduce the weight, but also make the device more safe and reliable. Martensite aging stainless steel heat treatment process is very simple, the manufacture of large cross-section of the other pieces, you can ensure that the entire cross-section uniform performance. Therefore, in recent years
