17-4 PH Stainless Steel
Specification
17-4 PH Stainless Steel is a precipitation hardening martensitic stainless
steel. Typical usage is seen in applications requiring high strength and a
modest level of corrosion resistance. Strength and toughness desired can
be manipulated by temperate range in the heat treatment process. Best
Stainless offers high quality standards including UNS S17400, AMS 5643,
ASTM A564, and ASTM A693 Grade 630.
Application
Nuclear reactor, Aircraft and gas turbines, Oil field, Chemical process
components, Paper mill, mechanical seals, pump shafts, Surgical and dental instrumentation.
