DIN 1.4568 AISI631 SUS631 X7CrNiAl17-7 17-7PH S17700 Stainless Steel wire

General Introduction

Alloy 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. 
Alloy 17-7 PH 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 ).
