Heated at 1900°F±25°F for 1/2 hour, air (Solution Treated) cooled or oil quenched to below 90°F. Normally performed at mill.
For most applications, 17-4 PH stainless should not be used in Condition A. This is true even though the desired tensile strength may be provided by that condition. The structure is untempered martensite that has low fracture toughness and ductility, while having poor resistance to stress-corrosion cracking. Superior service performance is assured by using 17-4PH stainless in the heat-treated condition.
For optimum machining results; if no aging condition is specified, H1150 should be used.
Condition A material heated at 900°F±15°F for 1 hour and air cooled. Maximum hardness but low toughness. Sensitive to stress corrosion cracking. Heating 4 hours improves toughness with about 4 ksi reduction in tensile and yield.
H925, H1025, H1075,
Condition A material heated 4 hours at specific temperature, and air cooled.
Condition A material heated 4 hours at 1150F, air cooled, heated again for an additional 4 hours at 1150F and air cooled.
Condition A material heated at 1400°F±25°F for 2 hours, air cooled, then heated at 1150°F±15°F for 4 hours and air cooled.
