What's the exact difference between M2 & 1.3343 steel grades

In summary, 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, while 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 in mechanical properties between the two grades is their hardness, with M2 having a higher hardness of 62-65 HRC (Rockwell C scale) compared to 1.3343 with a lower hardness of

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 ?

There are different grades of HSS for different purposes .

With low intensity machining and common metals most HSS grades are equivalent .

With high intensity machining some grades of HSS and some metals being machined will weld-bond at the cutting point and a lump of metal will accumulate which degrades the cutting action . This problem is reduced by selecting particular grades of HSS for particular metal being machined .
 

What is the chemical composition of M2 and 1.3343 steel grades?

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.

What is the main difference in mechanical properties between M2 and 1.3343 steel grades?

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.

Which steel grade is more suitable for high-speed cutting tools?

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.

Are there any differences in the applications of M2 and 1.3343 steel grades?

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.

Do M2 and 1.3343 steel grades have any other notable differences?

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.
