Introduction
- Properties：
- Good Hardness and Toughness：It has a good balance of hardness and toughness. After quenching and tempering, it can reach a hardness of HRC28 – 36, which enables it to withstand high loads and impacts, reducing the risk of deformation and cracking23.
- Excellent Wear Resistance：The alloying elements in the steel, such as chromium and molybdenum, contribute to its high wear resistance, making it suitable for applications where components are in frequent contact and friction, such as molds and dies123.
- High Hardenability：It has high hardenability, which means it can achieve a uniform and deep hardened layer during the heat treatment process, ensuring the stability and reliability of the material’s performance4.
