How much is N690 plate per kilogram
N690 die steel is often used for hardened tools and high-strength components because of its excellent mold characteristics such as super corrosion resistance, high strength, and high hardness. Such as making corrosion-resistant bearings, corrosion-resistant medical devices, optical products, hardened knives and other fields.
The supply form of N690 die steel: rolling, finishing, grinding
N690 application
Bailu N690 corrosion-resistant mirror mold steel undergoes electroslag resolubility (ESR) technology to make its structure more pure and fine, which is very suitable for hardened tools and high-strength components;
The application of N690 is as follows:
Suitable for corrosion resistant bearings
High-precision nozzles, valves, pistons
Cutting Surgical Instruments
Hardened Knives
refrigeration equipment
Packaging mold
