Products description 

 

D3,Cr12 Steel

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, not

secondary hardenable

 

The features 

 

 1. high carbon ang high chromium ledeburite steel.

 

 2. High wer 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

 

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

  Heat treatment

Hardness			59-63HRC					-
Anneal			830-870°C					≤269HB
Quenching			950-980°C					Air or oil cooling
Tempering			180-200°C					60-62HRC, tempering once
- 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.
