About Alloy 13-8

Alloy 13-8 stainless is a martensitic precipitation hardening stainless steel that has excellent strength, high hardness, superior toughness and good corrosion resistance.

Good transverse toughness properties are achieved by tight chemical composition control, low carbon content, and vacuum melting.

Alloy 13-8 stainless is usually available in an annealed condition, also known as solution heat condition or Condition A. In order to allow a complete martensitic transformation, the alloy is solution treated at 913-940°C for 15 to 30 minutes followed by air cooling or oil quenching to below 15.5°C. Aging temperature and time vary depending on the desired final properties, see Heat Treatment Conditions Table below.

Typical applications are large airframe structural components, motorsport components and injection molding equipment.
