Ovako 497Q is an ingot cast high tensile quench and tempering steel with very high strength and toughness. Ovako 497Q is an excellent choice for shafts and machine components. The high silicon content will give an improved tempering resistance. The grade is produced with the quality class IQ (isotropic quality). This ensures a very low number of elongated sulphide inclusions which will give more isotropic properties. The high oxidic cleanliness will enable the steel to meet the same high demands as for re-melted qualities. The carbon range will give a high surface hardness after surface induction hardening.
IQ-Steel® is an isotropic quality ultra clean steel optimized for high fatigue strength under multi axial loading.
