A2 steel is called DIN 1.2363 and JIS SKD12 steel. 1.2363 steel is a cold work mold steel that is improved on the basis of SKD11 steel. The toughness of 1.2363 steel is twice that of SKD11. The retained austenite is almost all decomposed under the conventional heat treatment conditions. The toughness of 1.2363 steel is great in the cold work mold steel. There are no cracks of industrial products due to be made of A2 steel round bar sheet plate material.
A2 Steel Application
The application is decided by A2 steel chemical composition and properties. It has high hardness and toughness. The application as below:
Precision stamping die.
Precision blanking dies for wire cutting and stamping die for various purposes.
Cold forging, deep drawing and boring molds.
High-speed punching punch, stainless steel plate punch.
Shear and slitter blades.
A2 Steel Characteristics
1.High toughness. The products that were made of A2 steel material almost no cracking or cracking occurs during the use.
2.The machinability is also better than SKD11 steel. Using 1.2363 steel can increase the service life of the mold and get higher production efficiency.
3.High quench hardening ability. so it can efficiently avoid the defects which be caused by insufficient hardness during vacuum heat treatment.
4.The surface hardness is higher after surface hardening treatment. It can efficiently improve the performance of the mold.

AISI O2 steel also can be called JIS SKS31 and DIN 1.2842 steel. It is the better type compare with the O1 tool steel. Its content of carbon, chromium and tungsten has been raised. So it has a higher hardenability characteristic, the deformation is small during the quenching. It is a low alloy tool steel which is better than carbon steel at the point of the mechanical property. It has high hardness and wearing resistance. Because of the certain account of vanadium element, the crystal grain is smaller then decrease the overheating sensitivity of the steel. At the meantime, the carbide is getting smaller and the distribution is uniformity.

What We Provide
Our main products are round and flat bars for alloy steel, tool steel, stainless steel, spring steel, bearing steel and etc. In those years we offers a wide range of high quality steel for engineering machinery, mold tooling, cutting tools manufacturing
O1 steel also is called DIN 1.2510 and JIS SKS3 steel. High content for manganese, chromium and tungsten in 1.2510 steel composition, that could increase the hardening ability. Then the steel does not need to undergo water quenching. After oil cooling and quenching, the hardness could reach 62HRC. O1 tool steel round bar sheet plate was used widely as a cold work mold steel. It is a great material for the blade, metal molds and etc.
O1 Steel Application
1.2510 steel is used as a material of tough parts. Such as punches, knock-out pins, cams, and of course, knife blades. And 1.2510 steel is mainly used for short-run tooling for cold forming dies, blanking dies, and cutting tools operating at ambient temperature. Typical applications for O1 tool steel are blanking, forming, and trim dies, gages, slitting cutters and etc.

D6 steel is a high-carbon, high chromium tool steel alloyed with tungsten that is characterized by high compressive strength, high wear resistance, high surface hardness and good hardening stability. It is also called SKD2 steel and DIN 1.2436 steel. And D6 steel chemical composition and heat treatment information are below.
Tool steels are primarily used to manufacture tools that can be used for machining metals, woods, and plastics. They are generally ingot-cast wrought products, and have the potential to be stable at elevated temperatures and withstand high specific loads.
D6 Steel Application
SKD2 steel chemical composition makes it become good tool steel in the industry. SKD2 steel is used for forming tools; molds for abrasive plastics and ceramics; long-run press tools; blanking and shearing tools for hard materials; stamping tools; scraping tools and etc.
D6 Steel Round Bar Sheet Plate Heat Treatment
Forging
SKD2 tool steel is heated slowly and uniformly to 700�°C (1292�°F) and then more rapidly to 900-1050�°C (1652-1922�°F).
Annealing
SKD2 tool steel is then annealed at 800-840�°C (1472-1544�°F) and cooled. Hardness of the steel after annealing will be approximately 225 Brinell.
Stress Relieving
Stresses from SKD2 tool steel can be eliminated before hardening by heating up to 650-700�°C (1202-1292�°F), if machining operations have been heavy. The steel is then allowed to cool slowly.
Hardening
SKD2 steel is pre-heated slowly to 750-800�°C (1382-1472�°F) and thoroughly soaked. Heating is then continued till the final hardening of 950-980�°C (1742-1796�°F), followed by air or oil quenching.
Tempering
The SKD2 steel is heated uniformly and thoroughly at the selected tempering temperature. Double tempering can also be carried out with intermediate cooling to room temperature.
Notice
We have our own cutting and processing equipment. Specifications can be cut and customized according to your requirements.

D3 steel also knows as DIN 1.2080 and JIS SKD1, which is a 12% chrome alloy steel. JIS SKD1 steel has very high wear resistance against abrasive and adhesive wear due to the high volume of hard carbides in the steel matrix, medium toughness, dimensionally stable, high compressive strength, not secondary hardenable.
D3 Steel Application
1.Highly stressed cutting
2.Punching tools for thin sheet
3.Blanking and forming dies
4.Forming rolls
5.Drawing and deep drawing tools
6.Slitting Knife
7.Stone processing tools
8.Pressure pads
9.Thermosetting plastic molding
D3 Steel Round Bar Sheet Plate Heat Treatment
Heat Treatment
SKD1 steel requires hardening and tempering to achieve maximum properties. For maximum accuracy, the parts of SKD1 tool steel should be stress relieved after roughing operations. Stress should be relieved at 648 C (1200 F) for one hour and cooled slowly.
Annealing
Annealing of SKD1 steel needs to be done in a controlled atmosphere furnace. D3 steels should be heated thoroughly to 871 C (1600 F) and cooled slowly at a rate of not more than -6 C (20 F) per hour, until the furnace is black. Then the material should be removed and air cooled.
Tempering
The SKD1 steel should be cooled to room temperature and should be tempered immediately. The parts should be placed in the tempering furnace and increased slowly to the desired tempering temperature. Tempering for 1 hour per inch of thickness is required.
Hardening
SKD1 steel should be heated properly since it is very sensitive to overheating and if not heated maximum hardness cannot be achieved. The work should be directly placed in a furnace preheated to 954 C (1750 F) and soaked for 20-25 minutes, plus 5 minutes per inch of thickness, and then oil-quenched to harden it.
Notice
Other specifications are determined by daily stock. Customization is also acceptable.
