Product Description
N690, as a new type of super corrosion resistant high strength die steel, is a new type of cobalt-Mo-vanadium martensitic stainless steel produced by electroslag resolution (ESR) technology.
N690 die steel is often used to harden tools and high-strength components due to its excellent die properties such as super corrosion resistance, high strength and high hardness. Such as making corrosion-resistant bearings, corrosion-resistant medical instruments, optical products, hardening tools and other fields.
N690 die steel supply form: rolled material, finishing, fine grinding
N690 application
N690 corrosion-resistant mirror die steel is treated with ESR technology to make its microstructure more pure and fine, which is ideal for hardened tools and high-strength components.
Its applications are as follows:
Suitable for corrosion resistant bearings
High precision nozzle, valve, piston
Cutting instrument
Hardening of the cutting tool
Refrigeration equipment
Encapsulation moulds
