Cr12 alloy tool steel

Cr12 Alloy Tool Steel

Cr12 alloy tool steel is a kind of high carbon, high chromium tool steel. It has good hardenability, hardness, wear resistance and toughness, and is widely used in cold stamping and cold forming process. The steel is normally supplied in annealed or normalized, and with higher hardness and wear resistance it can withstand higher cutting forces.

Cr12 is a versatile alloy steel with a wide range of potential applications including cutting, cold forging, and cold forging tools. It is often used for the production of high-end knives, scissors, saws, and razors, as well as hand tools such as chisels and hammers because of its ability to withstand extreme wear. Its high wear and corrosion resistance also makes it ideal for use in die-casting applications and as a wear surface for punches and dies.

Cr12 is also often used in cold work tooling applications such as blanking, drawing, and forming of sheet metal and thin profile materials. Due to its good wear and corrosion resistance, Cr 12 alloy is also often seen in mechanical engineering, the automotive industry, and the aerospace industry. It is also used to manufacture bead wire for automotive straps, and as a bearing material.

Cr12 alloy steels are heat treated at temperatures of 800-1000℃. This heat treatment can be used to improve its machinability, while also increasing its yield strength and wear resistance significantly. The alloy steel is also commonly carburized, which increases its surface hardness and wear resistance even further.

Due to its unique combination of properties, Cr12 alloy tool steel is one of the most widely used alloy steels in the industry today. Its high hardness, wear resistance, and ductility make it an ideal choice for use in any application requiring the highest levels of performance and reliability. Additionally, its relatively low cost makes it an attractive option for manufacturers on a tight budget.

解释

Cr12 alloy tool steel is a kind of cold working die steel with excellent overall performance, good abrasion resistance and strong heat treatment capability. Its carbon content (mass fraction) is 0.90-1.05, and the chromium content (mass fraction) is 11.50-13.00%.

Cr12 alloy tool steel has the characteristics of good comprehensive mechanical properties, high hardenability, good wear resistance and heat resistance , good comprehensive performance, and it is a kind of high-quality and widely used alloy tool steel. Its physical and mechanical characteristics are as follows:

1) Its density is 7.7g/cm³；

2) Its tensile strength is 1000-1200MPa;

3) Its yield strength is 930MPa;

4) Its elongation at break is 11%;

5) Its impact toughness is more than 90J/cm²;

6) Its hardness is HRC60-62.

Cr12 alloy tool steel is used to make cold working dies and cutting tools, often used for cutting tools with high hardenability. It is widely used in the manufacturing of cold saw blades such as circular saw blades and hacksaws. It can also be used for making cold punching dies, cold heading dies, cold shear blades, etc.

Meanwhile, Cr12 alloy tool steel with differential hardening treatment should also be used in combination with better wear resistance. As wear-resistant layer or quenching layer, it is used to increase the service life of the cold working dies and cutting tools. With proper heat treatment and higher quenching temperature, better performance of Cr12 alloy tool steel can be obtained.
