Stainless Steel, Precipitation HardeningAMS 5629 (13-8)

A precipitation hardenable chromium-nickel-molybdenum martensitic stainless grade.

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.

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

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.
