Description

  • 2311 Steel Properties
  • Nearest Equivalent : P20, ASSAB618

DIN 2311 is the Pre Hardened Plastic mould steel hardness distributed evenly in large cross sections that have excellent weldability with least hardness elevation, good mirror polishability and less streak texture making finishing easier. Size Section availability upto 255mm thickness. Supply hardness is 240-280 BHN.
