General Information

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.

IQ-Steel®  

IQ-Steel® is an isotropic quality ultra clean steel optimized for high fatigue strength under multi axial loading.
