Processing: RH950 - heated to austenitic range, 1040°C (1900°F), and water quenched. Reheated to 925°C (1700°F) to precipitate carbides. The austenite is transformed to martensite after cooling to room temperature and refrigerating at -75°C (-100°F). Tempered at 510°C (950°) Applications: high strength high temperature applications, chemical processing equipment, heat exchangers, power boilers, superheater tubes Corrosion Resistance: 17-7 PH is suitable for use in fresh water, industrial and marine atmospheres, and mild chemical and oxidizing environments. 17-7 PH should not be used in salt water or reducing environments. |
