Forms of supply

17-7 PH Stainless Steel sheet and strip.
Material is supplied in Condition A, ready for fabrication by the user.

Sheet and strip material are also produced in the hardrolled Condition C for applications requiring maximum strength.

STANDARD HEAT TREATMENTS
This material requires three essential steps in heat treating:
1) Austenite conditioning.
2) Cooling to transform the austenite
2) to martensite.
3) Precipitation hardening to
2) Condition TH 1050 or RH 950.

To obtain the highest mechanical properties from the alloy, Condition A material is transformed to martensite at
the mill by cold reduction to Condition C. Hardening to Condition CH 900 is accomplished with a single,

low-temperature heat treatment.
