Type 631 17-7 PH Stainless Steel Sheet UNS S17700 ASTM A579
Type 631 17-7 PH Precipitation-Hardened Stainless Steel Sheet UNS S17700 ASTM A579 overview
The two main properties of precipitation-hardened stainless steels are high corrosion resistance and high strength. Stainless steel grade 17-7 PH is a precipitation hardened stainless steel that possesses high strength and hardness, excellent fatigue properties, good formability, good corrosion resistance, and minimal distortion upon heat treatment.
Type 631 17-7 PH Precipitation-Hardened Stainless Steel Sheet UNS S17700 ASTM A579 Application
Stainless steel grade 17-7 PH is primarily used for applications requiring corrosion resistance, good strength, and mechanical properties up to 427°C (800°F) in operation. It is also commonly used for intricate parts due to its low distortion in heat treatment.
Stainless steel grade 17-7 PH finds uses in the following:
Variety of springs and washers
Chemical processing equipment
Heat exchangers
Power boilers
Superheater tubes
Components used in high-strength/high-temperature conditions
