General Information

25CrMo4 is a Cr and Mo alloyed quench and tempering steel with low carbon content. The steel combine high strength with high toughness.

  • 322A - is an ingot cast variant .
  • 6014 and 6016 are both M-steel

Delivered as rolled, soft annealed, normalized or quench and tempered. Weldable under certain conditions. 

M-Steel®

The basis for the concept is that non-metallic inclusions are modified and controlled with calcium treatment in a way to minimize tool wear and to maximize chip control in machining operations. Our M-Steel treatment can be applied to any steel grade.
