Material Notes:
VANADIS 4 is a chromium-molybdenum-vanadium alloyed steel which is characterized by:High wear resistanceHigh compressive strengthVery good through-hardening propertiesVery good toughnessExcellent dimensional stability after hardening and temperingGood resistance to tempering backVANADIS 4 is especially suitable for applications where adhesive wear and/or chipping are the dominating problems, i.e.with soft/adherent materials such as austenitic stainless steel, mild steel, copper, aluminum, etc. as work materialwith thicker work materialExamples:blanking and formingFine blankingCold extrusion toolingPowder pressingDeep drawingKnives
