As a leading manufacturer and supplier in Naypyidaw, Naing Steel is proud to introduce ARCELOR 400 Sheet and Plates, a cornerstone material for building Myanmar’s future. We understand that robust infrastructure and durable construction demand materials of exceptional quality and reliability. This high-strength steel is engineered to meet the rigorous challenges of modern projects, offering a superior combination of strength and versatility that our clients can depend on for their most ambitious endeavors, ensuring longevity and structural integrity.
ARCELOR 400 is a high-strength, low-alloy steel known for its excellent mechanical properties. Its composition includes carefully balanced elements that enhance its strength without sacrificing workability. This results in a material with a minimum yield strength of 400 MPa, providing exceptional resistance to force and deformation. It maintains good ductility, allowing it to be formed and fabricated with relative ease. This balance makes it tougher and more resilient than conventional steels, capable of withstanding significant stress and impact in demanding environments.
