13-8 stainless alloy (UNS S13800) is a martensitic precipitation-hardening stainless steel that has excellent strength, high hardness, superior toughness, and good corrosion resistance. Compared to other ferrous-base materials alloy 13-8 offers a high level of useful mechanical properties under severe environmental conditions. Alloy 13-8 is used in Aerospace components, landing gear, nuclear reactor components, petrochemical industry, injection molding equipment etc. Alloy 13-8 in the annealed condition can be strengthened further by relatively low temperature heat treatment.
