Annealed microstructure

Standard 2343 is delivered without any guarantee on the structure.

For applications requiring higher performances, an improved 2343 grade meeting the following requirements is available:

  • Structure fine and homogeneous without carbides at the grain boundaries
  • Structure in accordance with NADCA, SEP 1614-1 pictures: A5-B4-C2-D2-E1 or CNOMO max image D.

Please consult for more information.

Mechanical properties

2343 grade is delivered in annealed condition with a hardness <230HB. It has to be hardened after rough machining.
