Stainless Steel 17-7PH S17700 Cold Rolled Sheet SUS631 Strip In Coil
Stainless Steel 17-7PH S17700 Cold Rolled Sheet SUS631 Strip In Coil
17-7PH STAINLESS STEEL
- Good Formability
- High Strength
- Excellent Fatigue Properties
- Good Corrosion Resistance
- Minimum Distortion On Heat Treatment
Steel 17-7 PH is a precipitation-hardening stainless steel that 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 permissable.
In its heat-treated condition, this alloy provides exceptional mechanical properties at temperatures up
to 900°F (482°C). Its corrosion resistance in both Conditions TH 1050 and RH 950 is superior to that of
the hardenable chromium types.
In some environments, corrosion resistance approximates that of the austenitic chromiumnickel stainless steels.
In Condition CH 900, its general corrosion resistance is comparable to that of Types 302 and 304 stainless steels.
Fabricating practices recommended for other chromium-nickel stainless steels can be used for this material.
