Vanadis 60 SuperClean Steel

Vanadis 60 SuperClean Steel

Steel name: Vanadis 60 SuperClean
Diagram No.: 2771
Mat.No. (Wr.Nr.) designation: ~1.3292
Chemical composition in weight %: 2.30% C, 4.20% Cr, 7.00% Mo, 6.50% V, 6.50% W, 10.50% Co
Steel group: PM high speed steels
Properties: Uddeholm Vanadis 60 SuperClean could be hardened to a very high hardness and compressive strength. Uddeholm Vanadis 60 SuperClean has further the same good dimensional stability during heat treatment as the other Uddeholm Vanadis SuperClean grades. The toughness is despite the very high alloying content very good. The machinability is lower compared to lower alloyed HSS. The grindability of Uddeholm Vanadis 60 Super- Clean is equal or better than other high alloyed HSS, but somewhat lower than for Uddeholm Vanadis 30. SuperClean Uddeholm Vanadis 60 SuperClean has a very high hot hardness.
Applications: Uddeholm Vanadis 60 SuperClean is a high alloyed high performance PM high speed steel with an addition of cobalt. Uddeholm Vanadis 60 SuperClean is particularly suitable for cold work tooling where highest wear resistance and highest compressive strength are required at the same time.

Heat Treatment
Hardening: Pre-heating temperature: 450–500°C (840–930°F) and 850–900°C (1560–1650°F). Austenitizing temperature: 1100–1180°C, according to the desired final hardness, see diagram below. The tool should be protected against decarburization and oxidation during hardening.
Quenching media: Martempering bath at approx. 540°C (1004°F). Vacuum furnace with high speed gas at sufficient overpressure.
Tempering: For cold work applications tempering should always be carried out at 560°C (1040°F) irrespective of the austenitizing temperature. Temper three times for one hour at full temperature. The tool should be cooled to room temperature between the tempers. The retained austenite content will be less than 1% after this tempering cycle.
Diagram note: No data.
