Vanadis 30 SuperClean Steel

Vanadis 30 SuperClean Steel

Steel name: Vanadis 30 SuperClean
Diagram No.: 2770
Mat.No. (Wr.Nr.) designation: 1.3294
AISI/SAE designation: ~M3:2 +Co
Chemical composition in weight %: 1.28% C, 4.20% Cr, 5.00% Mo, 3.10% V, 6.40% W, 8.50% Co
Steel group: PM high speed steels
Properties: Uddeholm Vanadis 30 SuperClean is a W-Mo-V-Co alloyed PM high speed steel.
Applications: Uddeholm Vanadis 30 SuperClean is a cobalt alloyed high performance PM high speed steel. The cobalt addition of approx. 8,5% has a positive influence on the hot strength/ hot hardness, temper resistance and modulus of elasticity. The presence of cobalt has little influence on wear resistance. As cobalt does not form carbides, the wear resistance of Uddeholm Vanadis 30 SuperClean is more or less the same as for steels with the same base analysis but without cobalt (e.g. Uddeholm Vanadis 23 SuperClean). On the other hand, its presence reduces the toughness and hardenability somewhat but increases compressive strength and high temperature properties.

Heat Treatment
Hardening: Pre-heating temperature: 450–500°C (840– 930°F) and 850–900°C (1560–1650°F). Austenitizing temperature: 1050–1180°C (1920–2160°F), according to the desired final hardness.
Quenching media: Martempering bath at approx. 540‹C (1004‹F). Vacuum furnace with high speed gas at sufficient overpressure (~2 bar).
Tempering: 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.
