AMS 5604 / UNS S17400 / 17-4 PH Stainless Steel Sheet

AMS 5604 is an aerospace material specification for a corrosion resistant precipitation hardenable steel alloy. Common names for the alloy are 17-4, type 630, or UNS S17400.

AMS 5604 includes material in the form of sheet, strip, and plate. This alloy is typically used where a combination of strength and corrosion resistance is required in applications with service temperatures up to 600 deg F.

 

With the exception of forging stock, material to this standard is supplied in the solution heat treated condition that can be readily heat treated to final properties during the manufacture of component parts. To assure the results of the final precipitation hardening treatment; samples of the product are precipitation hardened to the H900 condition and tensile tested for conformance to specification minimum requirements.

 

17-4 PH has good fabricating characteristics and can be age hardened by a single step, low temperature treatment. 17-4 PH is a versatile material widely used in the aerospace, chemical, petrochemical, food processing, paper and general metalworking industries.
