Product Description

DIN 1.2379 Cold Work Die Steel SKD11 Cr12mov D2 Mould and Tool Steel

1.2379 .D2.SKD61 is a high-carbon high-chromium alloy tool steel, which has high hardness and wear resistance after heat treatment, and has the characteristics of strong hardenability and good dimensional stability.

The steel is an air-cooled hardened cold-work die steel widely used in the world. Smelted by electric furnace and re-dissolved by electroslag, high purity, better toughness, uniform structure, good high temperature strength, toughness and high temperature fatigue resistance, can withstand sudden temperature changes.

Heat Treatment condition

High hardness, high wear resistance eutectic carbide is uniform, good toughness, not easy to crack, hardness after quenching> 62HRC. Nitriding treatment time at 525 ºC is 20h / 30h / 60h, depth of ammoniated layer is 0.25mm / 0.30mm / 0.35mm, surface hardness of parts is 1250HV; nitriding treatment time at 570 ºC is 2h, nitride layer depth is 10 ~ 20μm, parts surface hardness 950HV.

Specifications

5.Feature: 

1.Vacuum degassing refining processing steel purity, suitable for polishing or etch processing plastic mold.
2. In pre-harden state delivery, no need for heat treatment can be directly used for mold processing, shorten the construction.
3. After heat treatment machining and polishing performance is good, the nitriding treatment, can be suitable for chrome plating surface treatment, such as material is the qualitative hardness is uniform (400mm thick), good toughness and good machining performance.
4.Good hardness uniformity and polishing property, good machining properties. 
5.Good integral mechanical performance under high temperatures. 
6.Good heat-resistance and fatigue-resistance.
7. Pre-hardened to HRC30-36 can be directly used for mold processing, shorten the construction period.
