Ovako 16CrMnNiMo9-5-2* 277Q Steel, +QT
Categories:	Metal; Ferrous Metal; Alloy Steel
Material Notes:	General Information: Ovako 277 is an air hardenable steel that is suitable for case hardening, nitriding or quench and tempering. By using air-hardening or gas quenching it is possible to reduce the amount of quenching distortion. Additionally the use of quenching medias such as oil and salt can be avoided, which improves both safety and environment. It is produced in two quality classes. 277L - Variant with regulated sulphur content for optimized machinability. 277Q - IQ Isotropic Quality for improved properties transverse to the rolling direction and better fatigue strength due to higher cleanliness level with a finer size distribution of non-metallic inclusions. The steel grade is made according to new process that modifies the the inclusion morphology, i.e. a lower number of elongated sulfides and reduced size distribution of oxides, both in avarage and in the spread. By using air hardenig or gas quenching it is feasible to reduce the amount of queching distorsion. Ovako 277 steels has very good welding properties. The steels high hardenability and good toughness properties provide a heat-affected zone that meets the high stated demands for the bulk material. Ovako 277Q will be classified as a Group 3 steel according to the standard Welding - Guidelines for a metallic materials grouping system (ISO/TR 15608:2005). Depending on heat treatment execution (yield strength) Ovako 277Q may be classified into subgroup 3.1 or 3.2. Maximum hardness that may be obtained in the HAZ of Ovako 277Q will be 450 HV10kg. IQ-Steel(Isotropic Quality) is an isotropic quality ultra clean steel. IQ-Steel is optimized for fatigue strength by a strict control of steel cleanliness. IQ-Steel, a further development of BQ-Steel, is an isotropic and ultra clean steel with properties that match re-melted steels. Based on thousands of examinations by Ovako into the effects of defects on fatigue performance, the metallurgy of IQ-Steel is purer and far more consistent than conventional grades, and designed specifically to perform well in multi axial loading. This enables the manufacturing of lighter, slimmed down components like gears, bearings and other critical parts. The steels are helping our customers to achieve new design solutions and implement higher standards of finished product performance. Key to these practical advantages are Ovako’s own unique, clean and consistent modern steelmaking processes that remove harmful inclusions and impurities from within the steel. IQ-Steels contain smaller and more fragmented inclusions and can handle much higher mechanical forces in all directions than conventional steels. IQ-Steels are newer, but already now well established in high pressure automotive applications. Modern diesel engines, with high and cyclic injection pressures, have proven to be an ideal application. Transmission components are another emerging area of strong interest.
