Compare SKD61 and 1.2344 steel

SKD61 and 1.2344 steels are both tool steels used for hot work. They are known for their high heat resistance and uniform machining. However, each SKD61 and 1.2344 steel grades are manufactured according to its own Standard.
So, what are the similarities and differences between them? Let's compare solid steel round SKD61 and 1.2344 okay.
1. Overview of SKD61 and 1.2344 steel grades
a. SKD61 steel
- SKD61 steel is a symbol of steel grade according to JIS standards of Japan.
- This is the steel line used to make hot stamping molds. Consists of 2 forms: Plate (Used to cast aluminum, zinc; household products, ...) and solid round form (Often used as machine parts).

b. Steel 1.2344
- Steel 1,2344 is the symbol of steel grade according to German DIN standard.
- 1.2344 steel is widely used in both hot and cold machining. In hot processing, 1.2344 steel is used for cutting and extruding blocks. In cold work, this steel is used to punch, tip and insert die blocks.
2. Compare solid steel round SKD61 and 1.2344 on chemical composition

Through the table of chemical composition above, we can easily compare steel 1.2344 and SKD61 are approximately the same. Therefore, in terms of characteristics, both have similarities as follows.
3. Comparison of steel 1,2344 and SKD61 in terms of mechanics
a. Mechanical steel SKD61
- SKD61 steel has high thermal stability, impact resistance is well balanced, very little deformation after heat treatment.
- Unsurpassed toughness and hot hardness;
- Anti-crack and abrasion resistant;
- Resists change during heat treatment;
- Suitable for hot pressure molds due to its high Vanadium content;
- Suitable for aluminum and magnesium dies;
- Hardness before heat treatment from 13 HRC - 17 HRC.
b. Mechanical and steel 1.2344
- High hardness and toughness;
- Excellent heat cracking, can be cooled by water at work;
- Has moderate abrasion resistance and can improve its surface hardness with Nitriding technology.
- Able to withstand heat under high temperatures, but using temperatures above 540 ℃ (1000 độ) hardness of rapid decline.
- Distortion rarely heat treatment.
4. Compare steel 1.2344 and SKD61 on application
a. SKD61 steel
- Common use in hot processing;
- Pressure molds for both aluminum and zinc;
- Forging dies;
- Metal extruders for light metals;
- Push core, furnace head, hot knife;
- Plastic cylinder.

                                                        Solid steel 1.2344 and SKD61
b. Steel 1.2344
- Hard plastic mold with high polish and long service life;
- Molds and aluminum alloys;
- Extruded aluminum molds (such as aluminum window frames, computer radiators);
- Hot forging molds (such as auto-connecting rods, rotors, stainless steel knives);
- Die casting molds (Radiater engines, lights for other decorative products).
