What is A693 GRADE 630 Stainless steel grade?
ASTM A693 type 630 is Standard Specification for Precipitation-Hardening Stainless and Heat-Resisting Steel Plate, Sheet, and Strip.
A693 type 630 are used for parts requiring corrosion resistance and high strength at room temperature or at temperatures up to 600°F (315°C). Parts of these steels are suitable for moderate. Others are capable of mild forming only. They are suitable for machining in the solution-annealed condition, after which they may be hardened to the mechanical properties specified in this standard without danger of cracking or distortion
