GB/T 9CrSi Cold Worked Mold Steel
The usage is:
1. Industrial cutting tools: 9CrSi is often used in the production of industrial cutting tools, such as slitting knives, guillotine blades, and paper cutting blades. Its high hardness and wear resistance make it ideal for cutting materials such as paper, plastic, rubber, and metal.
2. Woodworking tools: 9CrSi is also commonly used in the manufacturing of woodworking tools, such as chisels, planes, and saw blades. Its toughness and edge retention make it suitable for cutting and shaping wood, as well as other materials used in woodworking.
3. Metalworking tools: 9CrSi is used in the production of metalworking tools, such as punches, dies, and shearing blades. Its high hardness and wear resistance make it ideal for cutting and shaping metal, as well as other materials used in metalworking.

GB/T 9CrSi Cold Worked Mold Steel
| 1: GB/T 9CrSi steel introduction 9SiCr steel is a low-alloy cutting tool steel, but it is also often made of cold work mold parts, and the effect is very good. It has higher hardenability and hardenability than chromium steel (Cr2 or 9Cr2) and has higher tempering stability. Suitable for fractional quenching or isothermal quenching. This steel was first introduced from the former Soviet Union 9XC, used to be called 9CrSi steel. The composition and performance are exactly the same as 9XC. It has a long history of application in our country. The only similar foreign steel numbers are Germany's 90CrSi5, Sweden's 2092 and SR1855, DF-1. Similar steel numbers are not seen in other countries. The steel can be used for a variety of cold working die parts with complex shapes and small deformation requirements. 2: GB/T 9CrSi steel chemical composition |

5: Heat Treatment
Quenching: First, the 9CrSi is heated to 820 ~ 860℃, held for 2 hours, and then quickly cooled by oil cooling. The purpose of this step is to improve the hardness and wear resistance of the material.
Tempering: After quenching, the workpiece is heated to 180 ~ 200℃ for tempering to eliminate the internal stress and brittleness generated during the quenching process, while stabilizing the size of the workpiece and improving toughness.
6: Delivery conditionFor hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed, rough turned.
For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface.
For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
