General Information
Type 17-4 PH stainless steel is the most widely used of all of the precipitation-hardening stainless steels. Its valuable combination of properties gives designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs. Type 17-4 PH is a martensitic precipitation-hardening stainless steel that provides an outstanding combination of high strength, good corrosion resistance, and good mechanical properties at temperatures up to 316°C (600°F). Its unique combination of properties make this alloy an effective solution to many design and production problems.
HEAT TREATMENT
Grade 17-4 stainless steel is soaked at 1038°C (1900°F) for 30 min and cooled below 16°C (60°F) for complete martensite transformation in the condition A. The condition material is treated at 482°C (900°F) for 1 h followed by cooling. Solution treated material is soaked for 4 h at specific temperature in H925, H1025, H1075, H1100, and H1150 conditions followed by cooling in air.
Solution treated material is soaked at 760°C (1400°F) for 2 h in the H1150M condition followed by cooling. It is again heated at 620°C (1150°F) for 4 hours followed by cooling.
Common Applications of 17-4 PH
- Gate valves
- Chemical processing equipment
- Firearms production
- Pump shafts, gears, plungers
- Valve stems, balls, bushings, seats
- Fasteners
