Precipitation-Hardening Stainless Steel

Type 17-7PH (S17700)

General Properties

Type 17-7PH Precipitation-Hardening Stainless Steel in sheet and strip forms 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 600øF (316øC).

17-7PH is a precipitation-hardening stainless steel that provides high strength and hardness, excellent fatigue properties, good corrosion resistance and minimum distortion on heat treatment.

In the heat treated conditions, 17-7PH stainless steel possesses excellent mechanical properties at temperatures up to 900øF (482øC). Fabrication practices for 17-7PH stainless steel are similar to those used for other chromium-nickel stainless steels.

17-7PH stainless steel and strip is available in thicknesses from 0.015" to 0.135". Material is supplied in the annealed Condition A, ready for fabrication by the user. Sheet and strip 0.050 and thinner can also be supplied in the hard-rolled Condition C for applications requiring maximum strength.
