6.Characteristic |
pure steel vacuum degassing refining process ball the annealing softening treatment, good cutting performance.H13 picture strengthening elements vanadium, molybdenum special Add, abrasion resistance is extremely excellent |
||||||||||||||||
7.Usage |
H13 a high-carbon high-chromium alloy tool steel with high hardness and wear resistance after heat treatment and hardenability, good dimensional stability, suitable for making high-precision long-life cold work die and thermosetting molding plastic mold. |
||||||||||||||||
8.Physical properties |
H13 Hardness: before heat treatment H13 about HRC15 ~ 20 (HB200 230), the hardness after heat treatment: the internal of HRC40 ° ~~ 45 ° surface HV1000 ± 100 H13 density is 7.85 g per cubic centimeter |
||||||||||||||||
9.heat treatment |
Quenching: the first stage of warm-up; the second stage of 500 to 550 ° C, Preheat: 750 ~ 800 °C quenching or high-pressure gas cooling, 100 ~ 150 °C into the back to the stove. Tempering: Preheat: 300 to 350 °C tempering heating: 550 to 680 °C air cooling to room temperature, tempering three times. Quenching temperature of 1020 to 1050 degrees, hardness 56 ~ 58HRC, heat treatment of small deformation, surface nitriding nitriding processing products have better wear resistance. |
||||||||||||||||
|
10.Cryogenic treatment |
In order to obtain the highest hardness and dimensional stability, the mold immediately after the quenching cryogenic -70 to -80 ° C., maintained for 3-4 hours, and then in the tempering treatment, the cryogenic treatment of tool or mold hardness than the hardness of conventional heat treatment 1 -3HRC. Complex shape and size changes in large parts, cryogenic processing production risk of cracking | ||||||||||||||||
