 2.Form&Size 1)SKD61 Tool Steel round bars, flat/square bars,plates,sheets. 

                           Round steel bar: 10-800mm(Dia)

                           Flat steel bar: 6-400mm*200-1600mm 

                       2)SKD61 Tool Steel Size Available(Length can be customized) 

3.Surface Condition Black,turning,peeling,milling 

4.Characteristic  pure steel vacuum degassing refining process  ball the annealing softening treatment, good cutting performance. SKD61 picture  strengthening elements vanadium, molybdenum special Add, abrasion resistance is extremely excellent.

5.Usage  SKD61 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.

6.Physical properties SKD61 Hardness: before heat treatment SKD61 about HRC15 ~ 20 (HB200 230), the hardness after heat treatment: the internal of HRC40 °~ 45 ° surface HV1000 ± 100 SKD61 density is 7.85 g per cubic centimeter.

7.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. 

8. 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.
