Polishing Hot Forged Round Tool Steels ASTM H21 DIN 1.2581 JIS SKD5 BS BH21 NF Z30WCV9 3Cr2W8V
Descrition:
Properties: Under high temperature conditions, it has good toughness and strength, but toughness and plasticity is not good. Good quenching ability and thermal fatigue. As the temperature is higher, the plasticity, toughness and thermal fatigue is lower.
1,Size Available:
a) Round bar: Dia 16mm-600mm ,Length can be customized.
b) Flat bar: Thickness: 16-500mm Width: 200-1000mm ,Length can be customized.
2. Shaping: Hot forged / Hot rolled
3. Surface condition: Black surface/turning/milling/grinding/polishing
4. Annealing Hardness: HB241 max
Applications:
Widely used in making casting die, hot pressing die and stamping die requesting high bearing capacity, high thermal strength and tempering resistance. Widely used in male and female die, eg. Male and female die, insert block, cooper alloy pressing die, casting die used in horizontal forging machine. Mould can bear large stress, blending stress and tensile stress at the same time, eg. Inverted extrusion die. Thermal metal cutter bearing hot temperature.
