The steel grade 16MnCr5 is a case hardening steel with a carbon content between 0.14 and 0.19 %. It is intended for case hardening. In this process, carbon is introduced into the surface layer up to approx. 0.8% carbon content via a diffusion process (case hardening, carburisation, carbonitriding). After hardening, there is a hard, wear-resistant surface layer and a comparatively tough core that is able to absorb impact stresses without breaking.
Applications
DIN 16MnCr5 1.7131 steel is widely used for a variety of applications in the used to the gearings in rotating machinery. Typical applications such as valve bodies, pumps and fittings, the high load of wheel, bolts, double-headed bolts, gears, internal combustion engine. Electric locomotives, machine tools, tractors, steel rolling equipment, boring machine, railway vehicle, and mining machinery transmission shaft on the steel ball, roller and shaft sleeve, etc.
