Material 42CrMo4

Chromed rods from 42CrMo4 material are used in demanding work conditions. This material is used for highly mechanically stressed components. It has higher strength thanks to its carbon and chrome amount. These rods have high strength and toughness also at low temperatures. It is similar to 15 143 or 15 341 steel according to ČSN.

Parameters:
Tensile strength: 900-1200 N/mm2
Yield strength: min 650 N/mm2
Chrome layer thickness min 20 μm
Chrome layer hardness 66-67 HRC
