Naing Steel is proud to be a trusted manufacturer and supplier based right here in Naypyidaw, serving the growing needs of Myanmar’s industries. We specialize in providing high-quality Carbon Steel EN-9 Bars, a versatile and reliable material known for its excellent strength and durability. Sourced and produced with meticulous attention to detail, our EN-9 bars are the ideal choice for a wide range of demanding applications, ensuring your projects are built on a foundation of local expertise and unwavering quality you can count on.
The EN-9 grade is a medium carbon steel that strikes a wonderful balance between toughness and machinability. Its composition includes a higher carbon content, which gives it impressive tensile strength and good wear resistance. After proper heat treatment, these bars can achieve a remarkable hardness, making them significantly stronger than lower carbon grades. This combination of properties means EN-9 can be shaped and finished with relative ease while still holding up exceptionally well under stress and friction in demanding environments.
