What is Carbon Steel EN-45 Series Bars ?

The strength of our EN-45 bars comes from a carefully balanced composition, primarily iron and carbon, with silicon and manganese playing key supporting roles. This specific recipe gives the steel its notable toughness and excellent resilience under stress. After the right heat treatment, these bars develop a remarkable capacity to withstand significant impact and flex without fracturing, making them a go-to material for components where durability under demanding conditions is absolutely essential.
