Numeric designation1.2343 | AISI H11
Chemical designationX37CrMoV5-1
Stateformation of a hardening crack
EtchingV2A-Beize @ 70 °C

The formation of a hardening crack at a sharp cross sectional variation led to premature failure of a component of a plastic injection molding machine. Since the sharp notch is due to design, there is no heat treatment error. The matrix consists of a ferrite-free quenched and tempered structure.
