Mechanical properties：
hardness
Exercise hardness: After the M42 high-speed steel is heated, the hardness can reach 67-70HRC.
High temperature hardness: At 600°
C, its high temperature hardness can still be kept around 55HRC.
strength
Tensile strength: Its tensile strength range is 231-234 MPA.
Symbol strength: Dading strength≥154 MPA.
toughness
M42 high -speed steel has high toughness, its grains are uniform and high, and the toughness is high, suitable for making a tool with complex shapes.
Grinding performance
Due to the high cobalt content, the grinding performance of M42 high -speed steel is good, and it is suitable for making high -precision complex knives.
Thermal stability
M42 high -speed steel has excellent thermal stability. Even in high temperature environments, it can still maintain high hardness and wear resistance, suitable for processing high -hardness materials.
Abrasion resistance
Its abrasion resistance is excellent, carbides are small and high in hardness, and are suitable for cutting tools for making high wear resistance.
Application
1.Cutting tools: such as drills, milling cutters, scrapers, gear hobbing cutters, iron knives, etc.
2.Stamping dies: advanced punching dies, screw dies, punches with complex shapes, etc.
3.Cold forging dies and drawing dies: Due to their high hardness and wear resistance, they are suitable for manufacturing cold working dies.
