17-7PH Stainless Steel Bar

Medium corrosion resistance.


17-7PH offers an attractive combination of hardness and high strength with excellent fatigue resistance.

We stock 17-7PH stainless steel bars which combine medium corrosion resistance with excellent mechanical properties.


17-7PH is an American grade precipitation hardening stainless steel suitable for applications requiring excellent mechanical properties and medium corrosion resistance. The chromium-nickel-aluminium stainless steel offers an attractive combination of hardness and high strength with excellent fatigue resistance. The alloy provides good formability with minimum distortion after heat treatment. Hard-drawn 17-7 PH wire is a perfect spring material, particularly in manufacturing flat springs. When the wire is heat-treated at 482°C (900°F), the material takes on elastic characteristics resulting in a perfect wire for musical instruments or springs.


Aerospace

With such attractive performance characteristics, the alloy is popular in aerospace applications. Formability is good, but work hardens rapidly, so intermediate annealing may be required to produce intricate parts.
