Product Description
H13/1.2344/SKD61 Hot Rolled Alloy Steel Round Bar For Die Steel
Product IntroductionH13 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≥0.8c),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 Process:Electric-Furnace Smelting(EF)→Ladle Furnace(LF)→Vacuum Degassing(VD)→ Argon protected ingot →Multidirectional Forging → (Concave forging →)Normalizing+Hydrogen Diffusion Annealing → Ultrasonic Flaw Detection →Queching+Tempering Prehardened →Inspection→PackingRecommend heat treatment:
