1. High hardness and wear resistance Hardness is a fundamental characteristic that cutting tool materials should possess. Mechanical blades need to cut chips from the workpiece, and their hardness must be greater than the hardness of the workpiece material. The cutting edge hardness of the cutting blade used for cutting metal is generally above 60HRC. Wear resistance is the ability of a material to resist wear and tear. Generally speaking, the higher the hardness of the cutting blade material, the better its wear resistance. The higher the hardness and quantity of hard points (carbides, oxides, etc.) in the organization, the smaller and more evenly distributed the particles, and the better the wear resistance. The wear resistance is also related to the chemical composition, strength, microstructure, and temperature of the friction zone of the material. The wear resistance of the material can be expressed by the formula WR: WR=KICO.5E-0.8H1.43. In the formula, the higher the material hardness (GPa) e, the better the wear resistance. 2. Adequate strength and toughness In order for the cutting tool to work under high pressure, as well as the impact and vibration conditions that often occur during the cutting process, without causing blade breakage and breakage, the cutting tool material must have sufficient strength and toughness. 3. High heat resistance (thermal stability) Heat resistance is the main indicator of the cutting performance of Hengxing shear sheet materials. It refers to the performance of mechanical blade materials that maintain a certain degree of hardness, wear resistance, strength, and toughness under high temperature conditions. The cutting blade material should also have the ability to resist oxidation at high temperatures, as well as good resistance to adhesion and diffusion, that is, the protective material should have good chemical stability.
