I know the two steel grades: M2 tool steel and 1.3343 steels are similar. But the M2 has Mn element while 1.3343 has W elements. what would be the differences with such elements ?
The chemical composition of M2 steel grade is 1.05% carbon, 4.15% chromium, 1.00% vanadium, 5.00% molybdenum, and the rest being iron. On the other hand, the chemical composition of 1.3343 steel grade is 0.85% carbon, 4.00% chromium, 1.00% vanadium, 5.00% molybdenum, and the rest being iron.
The main difference lies in their hardness. M2 steel grade has a higher hardness of 62-65 HRC (Rockwell C scale), whereas 1.3343 steel grade has a lower hardness of 58-62 HRC. This difference in hardness affects their wear resistance and cutting performance.
M2 steel grade is more suitable for high-speed cutting tools due to its higher hardness and wear resistance. It can withstand high temperatures and maintain its hardness, making it ideal for cutting and shaping materials at high speeds.
Both M2 and 1.3343 steel grades are commonly used in high-speed cutting tools, but M2 is also used in cold work applications such as punches and dies. 1.3343 steel grade is also used in the manufacturing of machine parts and components that require high wear resistance.
One notable difference is their cost. M2 steel grade is more expensive than 1.3343 steel grade due to its higher content of chromium and vanadium, which contribute to its superior properties. Additionally, M2 steel grade is more prone to cracking during heat treatment, whereas 1.3343 steel grade has better heat treatment stability.
