30MoCrV20-7 Steel

30MoCrV20-7 Steel

Steel name: Ovako 499Q
Diagram No.: 2679
DIN designation: 30MoCrV20-7
Chemical composition in weight %: 0.28-0.32% C, 0.15-0.25% Si, 0.30-0.50% Mn, max. 0.025% P, max. 0.0015 S, 1.60-1.80% Cr, 1.80-2.20% Mo, max. 0.20% Ni, 0.40-0.60% V
Steel group: Tool steels
Properties: IQ-Steel is an isotropic quality ultra clean steel optimized for high fatigue strength under multi axial loading.
Applications: Ovako 499Q is a tool steel suitable for carburizing or used in quenched and tempered condition. The alloying strategy gives a high tempering resistance which make the steel suitable for using in elevated temperature applications. Ovako 499Q is produced through the Ovako IQ-process (isotropic quality) to a cleanliness comparable to VAR-remelted quality. Carburizing requires certain precautions due to the high alloying content. A low carbon po-tential should be used and pre-oxidation is recommended to enhance carbon diffusion. The strong carbide formers will give an excellent microstructural stability and excellent wear properties.
