Product Name: H13
Model: Hot work die steel H13
H13 is hot work die steel. Implementation of the standard GB / T1299-2000. In the case of H13 steel is C-Cr-Mo-Si-V steel, in the world of the application is extremely common, while many scholars have carried out extensive research, and to explore the chemical composition of the improvement. Its performance, use and 4Cr5MoSiV steel is basically the same, but because of its high vanadium content, so the temperature (600 degrees) performance is better than 4Cr5MoSiV steel, hot work die steel is widely used in a representative of the steel.
H13 Chemical composition:
Carbon C: 0.32 to 0.45
Silicon Si: 0..80 ~ 1.20
Mn: 0.20 to 0.50
Sulfur S: ≤0.03
Phosphorus P: ≤0.03
Cr Cr: 4.75 to 5.50
Molybdenum Mo: 1.10 to 1.75
Vanadium V: 0.50 to 0.80
50 ~ 500
2000 ~ 5800
20 ~ 400
80 ~ 1000
2000 ~ 5800
Hardness: annealing, 245 ~ 205HB, quenching, ≥ 50HRC
H13 is an electroslag steel, which has high hardenability and resistance to thermal cracking. The steel contains high levels of carbon and vanadium, has good wear resistance, has a relatively weak toughness and has good heat resistance , At higher temperatures with good strength and hardness, high wear resistance of the toughness, excellent comprehensive mechanical properties and high resistance to tempering stability.
H13 for the manufacture of large impact load forging die, hot extrusion die, precision forging die; aluminum, copper and alloy die casting mold.
Quenching: 790 degrees +15 degrees preheating, 1000 degrees (salt bath) or 1010 degrees (furnace control atmosphere) + - 6 degrees heating, insulation 5 ~ 15min air cooling, 550 degrees +6 degrees tempering; annealing, hot processing ;
