Product Details

1.2344 is the advantage of Tool & Die Steel. Here is a brief introduction to 1.2344 mold steel.
 
1. Characteristics and scope of application
1.2344 is a pressure resistant hot work die steel. The steel is remelted by electroslag, uniform in material, good in hardenability, excellent in machinability and polishing performance, high toughness and plasticity, good high and low temperature wear resistance, and high temperature fatigue and heat resistance.
characteristic:
1. Uniform material, superior machinability and polishing
2. High toughness and high plasticity
3. High wear resistance at high and low temperatures
4. Excellent overall hardenability
5. Good high temperature strength and thermal fatigue resistance
6. Very low deformability during heat treatment
7. It has better isotropic properties than traditional steel, and has excellent toughness and plasticity in all directions. 1.2344 is pressure resistant hot work die steel.
Scope of application:
1. Die-casting mold (mould, fixing, upper mold, nozzle, nitriding thimble)
2. Extrusion die (mold, support, choke)
3. Hot pressing mold, (aluminum, magnesium, copper alloy)
4. Parts, such as cold shear, flash, hot shear, wear parts
