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 |
Workmanship:
Die vacuum heat treatment and die surface treatment (N-O,C-N, carburize and nitridation surface treatment).
Recommend heat treatment:
| Heating temperature | Cooling way | Delivery Hardness (HRC) | Tempering temperature /ºC | Tempering number | Hardness (HRC) | ||
