VANADIS 6Critical tool steelparameters forGOOD TOOL PERFORMANCE• Correct hardness for the application• Very high wear resistance• High toughness to prevent premature failuredue to chipping/crack formation.High wear resistance is often associated with lowtoughness and vice-versa. However, in many casesboth high wear resistance and toughness are essentialfor optimal tooling performance.VANADIS 6 is a powder metallurgical cold worktool steel offering a combination of very high wearresistance and good toughness.TOOLMAKING• Machinability• Heat treatment• Dimensional stability in heat treatment• Surface treatment.Toolmaking with highly alloyed tool steels meansthat machining and heat treatment have to bemore considered than with the lower alloyedgrades. This can, of course, raise the cost of toolmaking.Due to the very carefully balanced alloying andthe powder metallurgical manufacturing route,VANADIS 6 has a similar hardening procedure asthe common cold work tool steels. In order to reducethe amount of retained austenite and tooptimize the abrasive wear resistance high temperaturetempering is recommended. One very bigadvantage with VANADIS 6 is that the dimensionalstability after hardening and tempering is muchbetter than for the conventional produced coldwork steels and for HSS used for cold work. Thisalso means that VANADIS 6 is a tool steel which isvery suitable for CVD and PVD coating.ApplicationsVANADIS 6 is suitable for long run tooling of workmaterials where mixed (abrasive–adhesive) orabrasive wear and/or chipping/cracking and/orplastic deformation are dominating failure mechanisms.Examples:• Blanking and fine blanking of harder workmaterials• Forming operations where a high compressivestrength is essential• Powder pressing• Substrate steel for surface coating• Plastic moulds and toolings subjected to abrasivewear conditions• Knives.GeneralVANADIS 6 is a chromium-molybdenum-vanadiumalloyed PM steel which is characterized by:• Very high abrasive-adhesive wear resistance• High compressive strength• Good toughness• Very good dimensional stability at heat treatmentand in service• Very good through-hardening properties• Good resistance to tempering back• High cleanliness.Typical C Si Mn Cr Mo Vanalysis % 2,1 1,0 0,4 6,8 1,5 5,4DeliveryconditionColourcodeSoft annealed to approx. 255 HBGreen/Dark greenRaufoss Teknologi AS, Verktygsfabriken, Norway.3
