20MnCr5 Steel ,also refers to DIN 1.7147 steel as per European standard EN10084.As the representative steel of the Chromium-Manganese series of case hardening steel,it has high strength and toughness.After quenching, the deformation is small and has good hardenability and low temperature toughness.20MnCr5 has relatively good machinability, but it is poor in welding performance.

20MnCr5/DIN 1.7147 Steel is usually used after carburizing and quenching or quenching & tempering.It is generally used for the manufacture and heavy-duty of large cross-section quenched and tempered parts and small cross-section carburized parts,also be used to manufacture medium and small parts with medium load and low impact,such as gears,shafts,friction wheels of variable speed equipment, worms, The sleeve of the governor,etc
