A36 Carbon Steel Coil Roll

A36 is an American standard carbon structural plate, following ASTM A36/A36M. This standard is applicable to riveted, bolted, and welded structures for Bridges and buildings, as well as general purpose structural steel quality carbon steel sections, plates, and bar steels. Its chemical composition is: C: ≤0.25, Si≤0.40, Mn: s0.80-1.20, P≤0.04, s:s0.05, Cu≥0.20 (when specified copper steel). Mechanical properties: Yield strength: 2250. Tensile strength: 400-550. Elongation: ≥20. The material similar to the national standard A36 is Q235.Carbon steel is an iron-carbon alloy with carbon content ranging from 0.0218% to 2.11%. Also known as carbon steel. Generally also contains a small amount of silicon, manganese, sulfur, phosphorus. The higher the carbon content of general carbon steel, the greater the hardness, the higher the strength, but the lower the plasticity.

Carbon Steel Coil

Hot rolled carbon steel roll than carbon steel a little elongation strength, good toughness and casting, stamping and welding, widely used in the manufacture of general machinery parts mainly used in buildings, Bridges, engineering quality requirements higher welding structure and bridge structure construction, ship construction industry, chemical industry, power plant the outer wall of pressure vessel, etc.

(1) According to the use of carbon steel can be divided into carbon structural steel, carbon tool steel and easy cutting structural steel three types, carbon structural steel is divided into engineering construction steel and machine manufacturing structural steel two;
(2) According to the smelting method can be divided into open hearth steel, converter steel;
(3) According to the deoxidation method can be divided into boiling steel (F), sedated steel (Z), semi-sedated steel (b) and special sedated steel (TZ);
(4) according to carbon content can be divided into low carbon steel (WC 0.25% or less) to carbon steel, medium carbon steel (WC0.25%0.6%) and high carbon steel (WC > 0.6%);
(5) According to the quality of steel, carbon steel can be divided into ordinary carbon steel (phosphorus, sulfur is higher), high quality carbon steel (phosphorus, sulfur is lower) and high quality steel (phosphorus, sulfur is lower) and super high quality steel.
