17-4PH Stainless Steel Sheet

Readily weldable with high strength.

17-4PH is a martensitic, precipitation-hardening stainless steel alloy with high toughness.

Our stock of 17-4PH high-strength stainless steel sheets benefits from high toughness and fatigue resistance.

17-4PH is chromium-nickel-copper stainless steel used for applications requiring high strength, high toughness, good corrosion resistance and high fatigue resistance. 17-4PH is a martensitic, precipitation-hardening stainless steel. The material offers good fabricability and can be age-hardened in a single low-temperature heat treatment. Corrosion resistance is the best of all standard hardenable stainless steels with similar performance to Type 304 in most environments. Due to the hardness of the material, formability is limited, although this may be improved significantly if the material is heat-treated before cold-working or hot-forming.

Versatility

17-7PH is a versatile engineering material finding use in the production of nuclear components, aerospace parts and military structures.
