Product type
Tool steel bars are high-performance steel products specifically designed for the manufacturing of tools and dies. They are made from a variety of alloying elements that enhance their hardness, wear resistance, and toughness. The production process typically involves forging and heat treatment to achieve the desired mechanical properties.
| Material | Alloy steel with varying compositions |
| Standard sizes | Round bars from 10 mm to 300 mm diameter |
| Hardness | Typically between 50 to 65 HRC |
| Heat treatment | Quenched and tempered |
| Typical grades | D2, O1, A2, S7 |
When selecting tool steel bars, consider the specific grade based on the intended application, as different grades offer varying properties such as hardness and toughness. It's important to specify the required dimensions, tolerances, and heat treatment processes. Additionally, inquire about certifications that may be necessary for your industry standards.
