Micro-Structure of NX2525
Micro-Structure of NX2525

Super micro grain structure improves wear and fracture resistance.


It covers a wide application range and thus reduces the number of tools required

  • NX2525 has high hardened Ti compound particles within it's microstructure therefore the grade has both excellent wear and fracture resistance properties.
