SUS631 CSP 3/4H Cold Rolled Stainless Steel Strip And Coil For Springs
 
JIS G4313 cold rolled stainless steel strip for springs
Precipitation hardening stainless steel SUS631 provides high strength and hardness,
excellent fatigue properties, good corrosion resistance, good formability,

and minimum distortion upon heat treatment.
This 17-7PH stainless alloy also provides benefits for other applications requiring high strength

and good corrosion resistance, as well as excellent properties for flat springs at temperatures up to 600°F (316°C).
 
This 631 stainless requires three essential steps in heat treating:
1) Austenite conditioning.
2) Cooling to transform the austenite
2) to martensite.
3) Precipitation hardening to
2) Condition TH 1050 or RH 950.
To obtain the highest mechanical properties from the alloy,
Condition A material is transformed to martensite at the mill by cold reduction to Condition C.
Hardening to Condition CH 900 is accomplished with a single, low-temperature heat treatment.
