Have a look at Uddeholm Vanadis 4 Extra SuperClean. Uddeholm has more types of tool steel to choose from. This is from Uddeholm PDF.
Pre-heating temperature: First pre-heating at600–650°C (1110–1200°F) and second at 850–900°C (1560–1650°F)Austenitizing temperature: 940–1180°C (1725–2160°F), normally 1020°C (1870°F).• For large sections, i.e. >70 mm (2.75") use 1060°C (1940°F).• For the very best wear resistance use 1100–1180°C (2010–2160°F).Soaking time: 30 min. for hardening tempera-tures up to 1100°C (2010°F), 15 min. fortemperatures higher than 1100°C (2010°F).Note: Soaking time = time at hardening tem-perature after the tool is fully heated through.A holding time of less than recommended timewill result in loss of hardness.Protect the tool against decarburization andoxidation during hardening.Further information can be found in theUddeholm brochure “Heat treatment of toolsteels. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
