Product Performance Options
Ovako 280 Hollow Bar is available with several heat treatment options to suit different industrial applications. In the cold drawn condition, it delivers even higher strength for demanding environments such as hydraulic cylinders and machine tools. The normalized condition is recommended where components need reliable impact strength at low temperatures, for example in shafts and transmission elements.
For applications that require very high tensile strength and hardness, Ovako 280 can be supplied in the quenched and tempered or case hardened condition, offering excellent dimensional stability with predictable changes during processing. These flexible performance conditions, based on the EN 10294 standard, make Ovako 280 a versatile choice for manufacturers seeking consistent quality and productivity.
