Overview of SKD61 hot stamping steel

The hot stamping mold operates according to the mechanism of ingot in the molten steel to melt. Then is shaped according to the design of the mold.
Hot stamping steel is a steel with great heat resistance, so they are often used to make dies. One of the typical steel grades is SKD61. And let us find out an overview of SKD61 hot stamping steel right in the following article.
1. Chemical composition of SKD61 steel
SKD61 steel has the following basic chemical components:
 - Carbon content accounts for about 0.39%, which is the decisive component of hardness and minimizes the deformation of steel due to impact during processing;
 - Chromium content accounts for about 5.15%, helping SKD61 steel increase resistance to rust, oxidation from the environment;
 - Molipden content accounts for about 1.4%, helping SKD61 steel to increase wear resistance, increase toughness;
 - Vanadium content accounts for about 0.8%, increasing heat resistance for SKD61;
 - Silicon content accounts for about 1%;
 - Manganese content accounts for about 0.4%;
 - Phosphorus content accounts for about 0.03%;
 - Sulfur content accounts for about 0.01%.

2. Basic physical properties of steel SKD61
 - Coefficient of thermal expansion: 12.5 (20 oC - 200oC);
 - Specific gravity: 7.8 g / cm3;
 - Thermal conductivity (W / mK): 24 (20oC);
 - Modulus of elasticity (GPa): 205.
3. Characteristics of SKD61 steel
 - Hot toughness and rigidity;
 - Outstanding abrasion resistance;
 - Heat resistance is quite high;
 - Little deformation due to heat;
 - Suitable for hot pressure casting (High Vanadium content).
4. Other basic applications of SKD61 steel
Besides the application of making hot stamping, SKD61 steel is also used for many different products such as:
 - Making details for aluminum molds (pouring, pressing), pin latches, slide barrels
 - Making injection molds, hot stamping pestles;
 - Volumetric stamping, thermally manipulated metal molds;
 - Widely used in pressure casting molds;
 - Gear, push core, full metal extrusion.
5. Some steel grades used for hot stamping are equivalent to SKD61
As mentioned, in addition to SKD61, there are some other steel grades that are used for hot stamping. These include SKT4, FDAC.

                                         Steel grade for hot stamping is equivalent to SKD61
An overview of the chemical composition can also see that their content is quite similar. However, SKD61 steel has Vanadium and Molyden content slightly better than the other two grades. Means heat resistance, better abrasion resistance. Because of that, SKD61 has become a hot stamping material used by many people.
In the process of processing hot stamping molds, in addition to high accuracy requirements, the quality and longevity of the parts are often required, so manufacturers often choose very carefully the steels to make molds to ensure products. achieve high accuracy and improve working capacity.
