20MnCr5 1.7147 Steel Material Round Bar Sheet Plate
20MnCr5 is structural alloy steel with great strength, toughness and hardenability. After heat treatment, 20MnCr5 material properties are better than 20Cr. Negligible quenching deformation, good low-temperature toughness. The machinability is good, but the welding property not as well. 20MnCr5(1.7147) steel material usually is used at the state that after hardening and tempering or carburizing and quenching.
