Product Description

SKD11 Tool Steel Plate  with good machinability

Description
 SKD11 Tool Steel Plate  with good machinability
SKD11 mold steel is a Japanese tool steel grade, which is produced by Hitachi and Datong steel mills. The Hitachi-produced SKD11 trade name is SLD (the latest improved version is called SLD-MAGIC), and the Datong steel plant trade name is DC11. Both have plants in the mainland, the most well-known in the industry, and the highest prices.
 
advantage
(1) Vacuum degassing refining, so the internal quality is extremely clean

(2) Good machinability

(3) Good hardenability, can be hardened by air cooling, no need to worry about quenching crack

(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 abrasion resistance, it is most suitable as a punching die for stainless steel or high-hardness materials

(6) Good toughness.

Factory hardness
Soft annealing to about HB210


High wear-resistant general-purpose cold work die steel; good hardenability and less heat treatment deformation.

SKD11 is a Japanese JIS standard grade. It is a wear-resistant and tough general-purpose cold-work die steel, high-carbon tool steel and vacuum-refined steel. The steel is pure, with good hardenability and hardening deformation. Good hardenability. The steel is spheroidized and softened, and the addition is good. The carbide particles are fine and uniform. It is not necessary to bear the special addition of quenching and cracking strengthening elements molybdenum and vanadium. High hardness and high wear-resistant eutectic carbides are uniform, high toughness, not easy to crack, hardness after quenching> 62HRC.

Nitriding treatment at 525 ºC, time 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. Nitriding layer Depth 10 ~ 20μm, surface hardness 950HV

Tool steel is the steel used to make cutting tools, measuring tools, molds and wear-resistant tools. Tool steel has high hardness and can maintain high hardness and red hardness at high temperature, as well as high wear resistance and appropriate toughness. Tool steel is generally divided into carbon tool steel, alloy tool steel and high-speed tool steel.Tool steel has good wear resistance, that is, the ability to resist wear. The tool can keep its shape and size unchanged under the conditions of considerable pressure and friction.
Process parameters
High-speed tool steel is also an alloy tool steel, which contains C, Mn, Si, Cr, V, W, Mo, Co. And it can be used to make high-speed rotary cutting tools, wear-resistant, high temperature resistant, which is Cr, The ratio of V, W and Mo is relatively large. Take W12Cr4V5Co5 as an example, Cr-> 3.75% -5%, V-> 4.5% -5.25%, W-> 11.75% -13%. The ratio of Cr and V should not be low Less than 3%. The content of P and S shall not exceed 0.030%.

The processing method of alloy tool steel is mainly pressure processing steel and cutting tool steel. There are many types of alloy tool steel, including cold work, hot work, non-magnetic, plastic mold steel, etc. At the same time, the ratio of Cr and V must not be too low. Selection of tool steel for cold work die

The choice of tool steel for cold work molds is based on the main failure mechanism of the mold in practical use. It is not enough to choose tool steel to have only knowledge of steel properties. It must also consider factors such as the number of parts produced, the type of material being processed, thickness, and hardness. A basic method of selecting tool steel is to first eliminate all the failure mechanisms except for wear, and then select the tool steel with the most suitable wear resistance to meet the production requirements.
