Cold Rolled Stainless Steel Coil Grade JIS SUS631-CSP 1/2H 3/4H H
Precipitation hardening steel JIS SUS631, 17-7PH, UNS S17700, EN 1.4568, DIN X7CrNiAl17-7
is a semi-austenitic stainless steel which is austenitic in the annealed condition, but martensitic in
the hardened condition. Type 631 provides high strength and hardness, excellent fatigue properties,
good corrosion resistance and minimum distortion upon heat treatment.
It is easily formed in the annealed condition, then hardened to high strength levels by simple heat
treatments to Conditions RH 950 and TH 1050.
The exceptionally high strength of Condition CH 900 offers many advantages where limited ductility
and workability are permissible. In its heat treated condition, this alloy provides exceptional mechanical
properties at temperatures up to 900 °F (482 °C).
