1.2344 hot-work tool steel
1.2344 is a hot-work tool steel. The EN designation is X40CrMoV5-1. AISI H13, Uddeholm Orvar and Böhler W302 are documented names. It is the most widely used hot-work tool steel. Typically soft annealed; hardening takes place at the toolmaker. INDUSTRISTÅL supplies bar, cuts to length and ships with 3.1. ESR and proprietary variants we promise only when the certificate can carry them.
