Ovako’s flat bar, made either from structural steel or boron steel, are developed for applications requiring high strength, good bendability and weldability. In addition, our steel offers benefits such as good impact toughness and high yield strength.
The steel used in Ovako’s flat bar 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 properties for the end product.
