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.
Delivery condition
For hot forged bar, usually the delivery condition is hot forged, annealed rough turned/Black surface.
For hot rolled bar, usually the delivery condition is hot rolled, annealed, Black surface.
For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface
For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
