SA573 Grade 58 structural steel bar stockist in zimbabwe

High-quality alloy steel is made of high-quality carbon structural steel by adding one or several alloying elements (the total mass fraction does not exceed 5%). The alloying elements contained are of different types and contents, and the corresponding properties are also different. High-quality alloy steel is mainly used to manufacture various parts that are larger in size, more complex in shape and difficult to meet performance requirements with high-quality carbon steel. Through proper heat treatment, , high-quality alloy steel can obtain higher strength and toughness.
