CarTech Custom 630 Stainless is a martensitic precipitation/age-hardening stainless steel offering high strength and hardness along with excellent corrosion resistance. It has good fabricating characteristics and can be age hardened by a single-step, low temperature treatment. It has been used for a variety of applications including oil field valve parts, chemical process equipment, aircraft fittings, fasteners, pump shafts, nuclear reactor components, gears, paper mill equipment, missile fittings, and jet engine parts.

When your application calls for extensive machining of this alloy, you should consider specifying a modified version, Custom 630 Project 70®+ stainless, for improved machinability.
