ASSAB Steel - S136 SUP
ASSAB High Toughness premium grade stainless tool steel

Delivered Hardness:
annealed to HB250

Chemical Content(%):
Cr-Ni-Mo-V type

Comparable Standard:
AISI 420 ESR Mod

Characteristics:

  • Excellent polishability
  • High corrosion resistance
  • Excellent through-hardening properties
  • Good ductility and toughness
  • Good wear resistance

Major Application:

  • Corrosion/staining resistance : moulding of corrosive plastics, e.g. PVC, acetates, and for moulds subjected to huid working/storage conditions
  • High surface finish : production of optical parts, e.g. camera and sunglass lenses. Moulding of medcal components, e.g. syringes and analysis vials
  • Toughness/ductility : complex moulds
  • Outstanding through-hardening characteristics : Large moulds quenched using a slow cooling rate are able to achieve desirable properties such as hardness, toughness and corrosion resistance even at the centre of large dimensions.
