Forged Hot Work Die Steel Round Bar H13 / 1.2344 /SKD61 For Die Casting Mould
Product Introduction
H13 is a hot work die steel, which is a steel grade formed by
adding alloying elements to carbon steel.
Chemical composition:
C | Si | Mn | P | S | Cr | Mo | V |
0.35-0.40 | 1.00-1.20 | 0.40-0.60 | ≤0.015 | ≤0.003 | 4.80-5.20 | 1.20-1.40 | 0.80-1.00 |
Features:
a),Electro slag remelting, annealing with diffusion process and
ultrafining heat-treatment has good microstructual homogeneity and
finer dispersed carbides.
b),High isotropy, aspect rations≥0.8
c),Good tempering performance, high toughness, high temperature
strength, good thermal stability and thermal fatigue resistance.
Hardness:
Annealing hardness | Quenching hardness | Tempering hardness |
≤230HB | 51-55HRC | 46-50HRC |
