Operating from the heart of Addis Ababa, Desta Steel proudly stands as your trusted local partner for high-quality steel solutions. We specialize in the supply and distribution of ASTM A204 grade B sheets and plates, a reliable material chosen for critical applications. Our commitment is to provide Ethiopian industries with robust products that meet stringent international standards, ensuring your projects are built on a foundation of durability and exceptional performance, backed by our dependable service.
The strength of ASTM A204 grade B lies in its balanced composition, primarily molybdenum, which gives it excellent performance in elevated temperature service. This grade offers a tensile strength of 515-655 MPa and a minimum yield point of 275 MPa, striking an ideal balance between resilience and formability. Its carefully controlled chemical makeup ensures superior resistance to pressure and heat, making it a dependable choice where ordinary carbon steel might fall short, providing long-term structural integrity.
