– It is annealed before ex-factory, which ensure good metallographic structure, proper hardness and good workability. There is no need to anneal again.
– But It must be re-annealed if reforged, as the original organization and performance are destroyed after reforged, and the forging stress increased.
– Normally it will be annealed twice and the temperature of the second annealed is 20°C lower than the first one.

The features

  1. high carbon and high chromium ledeburite steel.
  2. High wear resistance, hardenability, strong toughness, termal stablity, the compressive strength.
  3. Has high wear resistance, is a 3~4 times higher than average low alloy tool steel,quenching deformation small cabinet.

Applications

D3 tool steel is a 12% chrome steel, it has very high wear resistance against abrasive and adhesive wear due to the high volume of hard carbides in the steel matrix, medium toughness, dimensionally stable, high compressive strength.

It Highly stressed cutting and punching tools for thin sheets, profile rolls, drawing and deep drawing to ols, stone processing tools, knives for paper and plastics, shear knives for thin sheets.
