What distinguishes 1.2343 steel from 1.2344 steel?

This substance has a greater carbon content and is substantially harder and more wear-resistant than steel 1.2343 ESR.

Tool steels are hard, but why?

Tool steels typically include between 0.7 and 1.5 weight percent carbon. Some tool steels, however, can have up to 2.1% carbon.

What is the 1.2343 material’s hardness?

1.2343 / X37CrMoV5-1 and 1.2343 / X40CrMoV5-1 mechanical characteristics. given tempering at the given temperatures, hardness 300 C = 54,4 – 54,5 HRC. 350 C= 54,9 HRC.
