Hot-rolled flat bar

Flat bars by Ovako combines precisely controlled manufacturing processes for superior impact toughness, good surfaces and high yield strength across a range of applications. Ovako delivers hot-rolled flat bars in a broad dimension range. The bars are characterised by excellent straightness and shape as well as good surfaces and low decarburisation.

Straightness

The out of straightness is measured and our flat bars comply with European Standard EN 10058 as-rolled, but can also be delivered in the as-straightened condition.

Shape and dimensions
The rolled shape is generally flat bars with square corner edges. It can on request also be rolled as flat bars with different corner radiuses. The tolerances on dimensions for flat bars fulfill the European standard EN 10058. Our rolling mills have excellent capability to produce even tighter tolerances. The most common bar length is 6 meters, but can also range from 2.8 to 21 meters, depending on size and the producing rolling mill. Heat treatments may restrict the maximum length. Bars can be delivered sawn to exact lengths.

Hot-rolled spring steel flat bars

Ovako delivers hot-rolled spring steel flat bar according to European Standard EN-10092-1 (Profile A, B, C). The steel used in Ovako’s flat bars for spring manufacturing has very low levels of non-metallic inclusions and optimal hardenability. These contribute to a favorable yield to- tensile strength ratio in the quenched and tempered condition – a combination of properties that provides exactly the right qualities for the end product.
