1, density slightly higher than the density of carbon steel, stainless steel, ferrite and martensite in shape and slightly lower than that of austenite size stainless steel;
2, resistivity, resistivity according to carbon steel, iron, grain size, shape and austenite martensite stainless steel increasing sorting;
3, linear expansion coefficient of the size of the order is similar, minimal austenite size highest stainless steel and carbon steel;
4, carbon steel, iron, grain size and martensite stainless steel magnetic austenite size non-magnetic stainless steel, but its cold hardening generated when martensite phase transformation will produce a magnetic, can be used heat treatment method to eliminate the martensite structure and restore its non-magnetic.
