A36 Steel Flat Bar

Steel Flat Bar

The chemical composition of A36 flat steel mainly includes carbon, manganese, silicon and a small amount of sulfur, phosphorus and other elements. Among them, carbon is the most important element, and its content is between 0.26%-0.29%. The content of manganese is between 0.60%-0.90%, the content of silicon is 0.20%-0.40% with no more than 0.050%, and the content of phosphorus is no more than 0.040%. In addition, iron is its main component, occupying the majority of the weight.

The reasonable combination of chemical composition can improve the strength and toughness of A36 flat steel, making it more suitable for a variety of construction and manufacturing areas of use!

Carbon is one of the most important elements in A36 steel flat bar. Its content determines the hardness, strength and corrosion resistance of flat steel. Flat steel with higher carbon content usually has higher hardness and strength, but it is also more prone to rust. Therefore, a reasonable range of carbon content needs to be controlled when manufacturing A36 flat steel.

Manganese is another important element in A36 flat steel. It can increase the strength, hardness and wear resistance of steel, and improve the mechanical properties of steel and corrosion resistance. In actual production, the content of manganese is usually between 0.60%-0.90%, which can increase the mechanical properties of A36 flat steel, while avoiding the high content of manganese caused by the reduction of steel toughness.

Silicon is a common alloying element that increases the chemical resistance of steel while acting as a carbon diluter during processing and reducing the hardness of the steel. In A36 flat bar, the silicon content is usually between 0.20% and 0.40%, which achieves a slippery iron-carbon alloy that makes it suitable for a variety of industrial manufacturing and construction applications.

Sulfur and phosphorus are trace elements in A36 flat steel plates and have a minimal effect on the properties of the steel. Sulfur can affect the machinability and toughness of steel, while phosphorus can increase the strength and hardness of steel by accelerating the curing process. Therefore, it is necessary to control the content of both during production and manufacturing to maintain the basic properties of A36 flat steel.

Steel Flat Bar

Hot rolled steel flat bar refers to steel with a rectangular cross-section, the common specification is between 10-200mm in width and 2-20mm in thickness. The surface of flat steel is usually polished or frosted to have a smooth and flat appearance.

Carbon steel flat bar has high strength and excellent toughness to withstand heavy pressure and impact. The cross-section shape of hot rolled flat steel is rectangular, which can reduce the weight of the steel itself and improve the efficiency of use. Hot rolled flat bar has a smooth, flat surface and precise dimensions, making it easy to process, weld and install. The price of flat steel is relatively low and the cost is more reasonable.
