16MNCR5
Grade Introduction:
16MnCr5 steel is alloyed case hardening engineering steels for parts that require core tensile strength of 800 – 1100 N/mm² and good wearing resistance. It is an engineering material typically used to manufacture piston bolts, camshafts, levers, and other vehicle and mechanical engineering components. 16MNCR5 Grade is also available in different shapes like Round, Flat, Square steel Bars.
Grade Application
DIN 16MnCr5|1.7131 steel is widely used for a variety of applications in the used to gearings in rotating machinery. Typical applications such as valve bodies, pumps, and fittings, the high load of the 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.

Heat Treatment
When hardening 16MnCr5 heat treatment temperatures, including the rate of heating, cooling, and soaking times will vary due to factors such as the shape and size of each steel component. Other considerations during heat treatment include the type of furnace, quenching medium, and workpiece transfer facilities. Please consult a heat treatment specialist for full guidance on heat treatment of 16MNCr5 steel.
