GENERAL PROPERTIES

17-7 PH  is a precipitation hardening stainless steel that provides high strength and hardness, excellent fatigue properties, good corrosion resistance, good formability, and minimum distortion upon heat treatment. The alloy provides valuable property combinations particularly well suited for aerospace applications. This special alloy also provides benefits for other

applications requiring high strength and good corrosion resistance, as well as excellent properties for flat springs at temperatures up to 315°C(600°F ).

 

CORROSION RESISTANCE

Corrosion resistance in Conditions TH 1050 and RH 950 is generally superior to that of the standard hardenable

chromium types of stainless steels 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.

 

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. Spring-back is similar to that of Type 301. This alloy is

extremely hard and strong in Condition C. Therefore, fabrication techniques for such materials must be used.
