18CrNiMo7-6 is the brand of EN 10084 surface hardening steel. It is the method of steel number representation of the European Standardization Commission. Its number number is 1.6587.
Surface hardening steel is a high-quality structural steel with lower carbon content. After forming, the carburizing or nitrogen seepage process, and quenching process can obtain the structural parts of the surface and the high tough core part with a high-strength and high-strength core.
It is widely used in gearbox gears, with high bending strength, contact fatigue strength, 18CrNiMo7-6 also has high hardness and abrasion resistance, and the heart has high hardness and toughness. Comprehensive mechanical performance is high.
