17-4PH Stainless Steel Bar (ASTM A276/276M)
Technical Data Sheet
17-4PH is a martensitic, precipitation-hardening stainless steel
that provides an outstanding combination of high strength and
hardness along with excellent corrosion resistance. 17-4PH has good
fabricating characteristics and can be age hardened by a single
step, low temperature treatment. 17-4PH is a versatile material
widely used in the aerospace, chemical, petrochemical, food
processing, paper and general metalworking industries.
