PH15-7MO (Type 632)'s basic performance is similar to 0CR17NI7AL steel, but the comprehensive performance is better than it. In the austenitic state, you can withstand various cold forms and welding processes, and then get the highest strength after heat treatment; there is excellent high temperature strength below 550 ° C. It is used in the manufacturing aviation thin -walled structural parts, various containers, pipes, spring, valve film, ship shaft, compressed machine disc, reactor components, and a variety of chemical equipment.
