Machinability of stainless steel Grade 17-7 PH is rated at 75 % of B1112. On machining, this alloy shows long gummy chips and requires chip breakers. While machining will provide excellent results the slow speeds and constant feeds are recommended.
Applications Stainless Steel Grade 17-7 PH is basically utilized for applications requiring corrosion resistance, good strength, and mechanical properties up to 427°C (800°F) in operation. It is commonly utilized for intricate parts because of 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
Super heater tubes
Components used in high-strength/high-temperature conditions
Environment
Safety
