1.2316


1.2316 Steel is a pre-hardened material with good corrosion resistance(due to good Cr content).We have imported material,i.e.,Germanybased.It belongs to P20 family.


Properties

  • Good Hardenability
  • Good Firmness

Good Corrosion Resistance

  • Excellent Resistance to the wear
  • Good Workability
  • Good Polishability
  • Uniform Hardness in all Dimensions
  • Easily Machineable
  • High Surface finish and Polishability
  • Not suitable for nitriding and chrome plating due to the high chrome content.

Form of Supply

All sizes are available(both flat and round).

Applications

Heat slowly and uniformly at 1000°C. After forging ,it is to be cooled slowly in furnace or in an thermoinsulating material.


Slowly heated to 780°C and then cooled slowly in furnace to 600°C and then it has to be air cooled.


Soaking is done  at temperature 600 – 650°C and then it is furnace cooled. This process is done at approx. 650 °C.


1020 – 1040 °C
