Austenitic manganese steel
With its high elongation coefficient and its tendency for surface cold work hardening under stress, VAUTID austenitic manganese steel is an outstanding solution for components that are subject to impact. It has understandably become a firm fixture in the VAUTID product portfolio.
Mechanical properties
VAUTID castings made from austenitic manganese steel are used in crusher jaws and crusher cones.
