SKD11 is a general-purpose cold work die steel with high wear resistance and toughness, high carbon and high chromium alloy tool steel and vacuum degassed refined steel. The steel is pure and has good hardenability and small quenching deformation.
SKD11 steel is softened by spheroidizing annealing and has good machinability. The carbide particles are fine and uniform. There is no need to worry about the special addition of molybdenum and vanadium, which is the quenching cracking strengthening element.
SKD11 is produced by Hitachi and Datong Steel Plants. Hitachi’s SKD11 is produced under the trade name SLD (the latest improved version is called SLD-MAGIC), and Datong Steel Plant’s trade name is DC11. Both have factories in the mainland, and are the most well-known in the industry, and the prices are also the highest. The steel is a kind of air-cooled hardening cold work die steel widely used internationally. Smelted by electric furnace and remelted by electroslag, it has high purity, better toughness, uniform structure, good high temperature strength, toughness and high temperature fatigue resistance, and can withstand sudden temperature changes.
High hardness, high wear resistance eutectic carbide uniform, good toughness, not easy to crack, the hardness after quenching> 62HRC. The nitriding treatment time at 525℃ is 20h/30h/60h, the nitriding layer depth is 0.25mm/0.30mm/0.35mm, the surface hardness of the part is 1250HV; the nitriding treatment time at 570℃ is 2h, and the nitriding layer depth is 10~ 20μm, the surface hardness of the part is 950HV.

characteristic
1. Good high temperature strength and toughness, better wear resistance, easy to cut;
2. SKD11 is a kind of cold die steel with a good balance of strength, toughness and heat resistance. In recent years, with the development of isotropic products, it has gradually developed to high toughness and other aspects. It can make the die life longer and performance It is more stable, easy to process, and less deformed by heat treatment.
Folding product features
(1) Vacuum degassing and refining are carried out, so the internal quality is extremely clean.
(2) Good machinability.
(3) Good hardenability, air cooling can harden, no need to worry about quenching cracking.
(4) The heat treatment deformation is very small, the quenching deviation is very small, and it is most suitable for molds with precision requirements.
(5) Excellent wear resistance, most suitable for punching die for stainless steel or high-hard materials.
(6) Good toughness.
use
SKD11 is the most widely used mold material for aluminum and zinc die casting. This steel contains tungsten high temperature resistant high-grade alloy steel, suitable for hot work, aluminum, magnesium, zinc, copper alloy die-casting molds, grooving knives, scissors and heat Forging operations, plastic molds, hot work reamers, rolling knives, general hot work forging dies, hot bolt dies, hot tools, etc.
Folding method of use
Used in the "quenched + tempered" state
Use in the state of "quenching + cold treatment + tempering" (suitable for high precision and dimensional stability requirements)
Use in the state of "quenching + tempering + nitriding" (suitable for high surface hardness requirements)
When cutting the material, the saw blade speed should not be too fast, 25m/min is appropriate, and the sawing efficiency is maintained at about 9cm2/min ~ 20cm2/min.
