Ideal for the motorsport industry
Alloy 13-8 can be used in a variety of applications, here are just a few examples:
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.

13-8 stainless is a martensitic precipitation hardening stainless steel that has excellent strength, high hardness, excellent toughness and good corrosion resistance. Transverse toughness properties are achieved by tight chemical composition control, low carbon content, and vacuum melting.
Appropriate heating and cooling control is required to prevent cracking and to produce acceptable properties across the weld zone. Alloy 13-8 and others such as alloy 410, alloy
A 286 and Aermet® 100 are weld-able but should be welded in the solution annealed or overaged condition with preheat and post weld treatments applied as appropriate.
The high tensile strengths of precipitation hardening martensitic stainless steels come after a heat treatment process that leads to precipitation hardening of the martensitic matrix. Hardening is achieved through the addition of one or more of the elements Copper, Aluminium, Titanium, Niobium, and Molybdenum.
Applications were very high strength and toughness are required in the aircraft industry includes: landing gear components, shafts, valves, fittings and fasteners.
