DELIVERY STATUS

Annealing, hardness Hb≤255 

DELIVERY SIZE

Thickness 5~300mm, width 210~810mm, length 2000~3000mm

Round bar φ5~φ300mm,length 2000~3000mm

The Main Purpose

1. For powder pressing die mold,shearing machine mold,add fiberglass to plastic mold etc.

2. Suitable forvibration and shock load to withstand the mold:deep drawing mold,punching die mold.

3. Metal cutting saws,cold heading and extrusion tools ect.

The Main Characteristic

1. Cold forging die mold,stamping die mold,with the advantages of small carbide non-uniformity and high toughness.

2. Easy to overheat, should strictly control the quenching temperature; The protection of heat treatment is more stringent.

3. Due to good hardness and wear resistance, it used for cutting tools that cut harder cutting materials.

4. High-speed steel M2 has a greater tendency to carbide, So the protection of heat treatment requirements more stringent, suitable for vibration and shock
