Custom 17-7 PH Stainless Steel Springs, Stampings & Wire Forms

Please note that we do not sell 17-7 PH stainless steel or any other materials in raw form. Stainless steel is a material option for custom springs, wire forms, etc., manufactured by Peninsula Spring.

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

17-7 PH Stainless SteelHigh strength 17-7 PH is suitable for use in fresh water, industrial, and marine atmospheres, as well as mild chemical and oxidizing environments. 17-7 PH should not be used in salt water or reducing environments.

The alloy provides valuable property combinations that are particularly well suited for aerospace applications and other applications that require high strength and good corrosion resistance. It is an ideal choice for custom flat springs and custom wire forms used in temperatures up to 650°F (343°C).
