PowderRange® H13 is a versatile air hardening, 5% chromium hot work steel. It exhibits a good combination of high toughness, temper resistance, and thermal fatigue resistance. PowderRange® H13 has challenging weldability in laser and electron-beam additive manufacturing processes, where part geometry and build parameters could induce micro-cracking.

Key Properties

  • High impact toughness and good ductility
  • High temperature strength
  • Good abrasion resistance at temperature
  • Resistance to thermal fatigue
  • Limited distortion during hardening



  • Tooling for extrusion and molding
  • Valves and fittings
  • Pumps and impellers
  • Manifolds
  • Die casting

The mechanical and physical properties of any additively-manufactured

material are strongly dependent on the processing conditions used to

produce the final part. Significantly differing properties can be obtained by

utilizing different equipment, different process parameters, different build

rates and different geometries. The properties listed are intended as a

guide only and should not be used as design data.

The information and data presented herein are typical or average values

and are not a guarantee of maximum or minimum values. Applications

specifically suggested for material described herein are made solely for the
