Material Notes:
Chromium-molybdenum-tungsten-vanadium alloyed PM steelVanadis 23 is a high speed powder metallurgical steel, recommended for low temperature die casting applications and warm forging applications where wear resistance above that of an ORVAR 2M / AISI H13 is required. This material is available in limited sizes.Vanadis 23 is characterized by:High wear resistance (abrasive profile)High compressive strength Very good through-hardening properties Good toughnessVery good dimensional stability on heat treatmentVery good temper resistanceApplications: Uddeholm Vanadis 23 is especially suitable for blanking and forming of thinner work materials where a mixed (abrasive–adhesive) or abrasive type of wear is encountered and where the risk for plastic deformation of the working surfaces of the tool is high, e.g.:
