Properties: Uddeholm Vancron SuperClean is a nitrided powder tool steel, which means that a “surface coating” is already integrated into the finished tooling material. The result is a tool surface with very low friction that reduces galling or sticking of the material. Uddeholm Vancron offers the possibility of eliminating time- and costconsuming surface coatings like PVD or TD. This is achieved already in the manufacturing process of Uddeholm Vancron by introducing an extra nitriding operation. Benefits for the tool user include improved and consistent quality of the manufactured parts, especially regarding the surfaces. More reliable delivery time and higher utilization of the production equipment are also benefits, with fewer disturbances and interruptions in production. Further improvements include simplified maintenance, which can often be made in-house as no surface coating is required; and as well, total tool life is increased. The tool maker can produce a high quality tool that does not require any surface coating, which means a shorter delivery time and freedom to make adjustments after the heat treatment. In total this means that the product quality will be uniform from the first part produced to the last and that a tool manufactured in Uddeholm Vancron will make it easier for you to keep your promises.
Applications: Uddeholm Vancron is a cold work tool steel with an excellent galling/adhesive wear profile, which makes the steel ideal for severe production conditions and/or long run production in applications where surface coated tool steel is needed. The work materials in these applications are often soft/ ad-herent materials such as austenitic and ferritic stainless steel, mild steel, copper, aluminium, etc. Uddeholm Vancron should be used in cold work applications where the predominant failure mechanisms are adhesive wear or galling.

Heat Treatment
Hardening: The hardenability for Uddeholm Vancron is equivalent to Uddeholm Vanadis 23, which ensures good through hardening properties at quenching in salt bath or gas quenching in vacuum furnace.
Pre-heating in two stages: 600–650°C (1110– 1200°F) and 850–900°C (1560–1650°F).
Austenitizing temperature: 950–1150°C (1740–2100°F) normally 1080°C (1980°F).
Holding time: 30 minutes (10 minutes at 1100°C (2010°F) and above.
We always recommend a sub-zero treatment when a hardening temperature of 1100°C (2100°F) or above has been used.
Tempering: The recommended austenitizing temperature is 1080°C (1980°F) with 30 minutes holding time followed by quenching and tempering at 540°C (1000°F)/3 x 1 h resulting in a hardness of 63–64 HRC.
