From the heart of Addis Ababa, Tariku Metals is proud to be a trusted name for specialized steel solutions. We understand that the backbone of Ethiopia’s growing industries relies on high-quality materials, which is why we specialize in the manufacturing and supply of precision-engineered 20MnCr5 round bars. Our commitment isn’t just to meet specifications, but to exceed expectations, ensuring every bar we deliver supports the strength and durability your critical projects demand, right here in our dynamic city.
The 20MnCr5 grade gets its reliable strength from a specific blend of elements, primarily carbon, manganese, and chromium. This composition allows the steel to be effectively hardened through heat treatment processes. Once treated, these round bars exhibit an excellent combination of high tensile strength, good toughness, and impressive wear resistance. This makes them exceptionally durable and capable of withstanding significant stress and fatigue, which is essential for components that are constantly in motion under heavy loads.
