Naing Steel stands as a trusted manufacturer and supplier in Naypyidaw, dedicated to providing the robust strength and reliability that Myanmar’s growing industries depend on. We take pride in our production of Carbon Steel EN-24 Bars, a material chosen for its exceptional performance in demanding applications. Our commitment lies in delivering not just a product, but a foundational component that empowers your most critical projects, ensuring they are built on a foundation of local quality and proven durability.
The EN-24 bar is defined by a carefully balanced composition, primarily nickel, chromium, and molybdenum, which gives it its notable characteristics. This alloy mix allows the steel to be heat-treated to achieve impressive mechanical properties. Once processed, it offers a high tensile strength alongside good ductility and remarkable toughness. This combination means it can withstand heavy loads and resist impact, making it a go-to material for parts that simply cannot afford to fail under stress.
