Ovako’s flat bars, made either from structural steel or boron steel, are developed for applications requiring high strength, good bendability and weldability. Beside these properties, our steel offers benefits such as good impact toughness and high yield strength.
The steel used in our flat bars for spring manufacturing enjoys a very low level of non-metallic inclusions and optimal hardenability, which contributes to a favourable yield to tensile strength ratio in the quenched and tempered condition – a combination of properties that gives the end product, springs, exactly the right properties.
