17-7 PH Stainless Steel Corrosion Resistance
Corrosion resistance in Condition TH 1050 and RH
950 is generally superior to that of the standard hardenable chromium types of
stainless steel such as Types 410, 420 and 431, but is not quite as good as
chromium-nickel Type 304. Corrosion resistance in Condition CH 900 approaches
that of Type 304 in most environments.

Heat Treatment for 17-7 PH Stainless Steel
This material requires three essential steps in heat treating:
1) Austenite conditioning.
2) Cooling to transform the austenite to martensite.
3) Precipitation hardening to Condition TH 1050 or RH 950.
To obtain the highest mechanical properties from the alloy, Condition A
material is transformed to martensite the mill by cold reduction to Condition
C. Hardening to Condition CH 900 is accomplished with a single,
low-temperature heat treatment.

Workability for 17-7 PH
Stainless Steel
Formability
In Condition A, the alloy can be formed comparably to Type 301. It work
hardens rapidly and may require intermediate annealing in deep drawing or in
forming intricate parts. Springback is similar to that of Type 301. This alloy
is extremely hard and strong in Condition C. Therefore, fabrication techniques
for such material must be used.
Weldability
The precipitation hardening class of stainless steel is generally considered
to be weldable by the common fusion and resistance techniques. Special
consideration is required to achieve optimum mechanical properties by
considering the best heat-treated conditions in which to weld and which heat
treatments should follow welding. This particular alloy is generally
considered to have poorer weldability compared to the most common alloy of
this stainless class, 17-4 PH stainless steel. A major difference is the high
Al content of this alloy, which degrades penetration and enhances weld slag
formation during arc welding. Also, the austenite conditioning and
precipitation hardening heat treatments are both required after welding to
achieve high strength levels. When a weld filler is needed, 17-7 PH is most
often specified.
