0Cr17Ni7Al
0Cr17Ni7Al is a precipitation hardening type steel with aluminum added, corresponding to the American brand 17-7PH. It is a dispersion hardening stainless steel with high strength, high hardness, fatigue resistance, corrosion resistance, good forging property, and less high temperature deformation, which is especially suitable for aerospace field. This special alloy is also suitable for other fields with high strength and corrosion resistance requirements. When the high temperature reaches 316 ℃, the spring performance is still very good. It can be used in aerospace, chemical, petrochemical, paper and metal processing industries.
