Material Notes:
Processing: Condition C - heated to austenitic range, 1040C (1900F), and water quenched. Severely cold worked (60-70%). The cold working induces a martensite transformation in the austenite.

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.
