Characteristics DIN 20MnCr5 / 20MnCrS5 grade is a low-alloy steel containing chromium as strengthening agent. The steel has good strength and toughness in low temperature, hardenability and machinability, less deformation after heat treatment, but poor weldability
Applications This low-alloy steel can be case hardened, or quenched and tempered, for carburized parts as well as quenched and tempered parts with large section under heavy bent load and speed, such as gear, connecting rod, shaft, worm, sleeve, friction wheel, gear pump without heavy impact, water pump rotor, clutch, bolt for high pressure vessel, etc.
What we can offer? We offer a wide range of steel products in a wide variety of dimensions and executions, acc.to the common international specifications or customerized.
Machining and heat treatment are available.
Also, we advise you in choosing the right materials.
