Precipitation hardening steels are characterised into one of three groups based on their final microstructures after heat treatment. The three types are: martensitic, semi-austenitic and austenitic.<\/p>

Martensitic precipitation hardening stainless steels have a predominantly austenitic structure at annealing temperatures of around 1040 to 1065\u00b0C. Upon cooling to room temperature, they undergo a transformation that changes the austenite to martensite.<\/p>

AMS5629 (13-8) is a martensitic precipitation hardening stainless steel. Heat treatment provides 13-8 with high strength. It comes in various conditions offering an array of properties. Good transverse toughness properties are achieved by tight chemical composition control, low carbon content, and vacuum melting.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t
