SA283 grade D carbon steel plate sheet hot rolled plate thickness tolerance

SA283 grade D carbon steel plate sheet controlled rolling is that, on the basis of adjusting the chemical composition of SA283 grade D carbon steel plate sheet, by controlling the heating temperature, rolling temperature, deformation system and other process parameters, the change law of austenite structure and the microstructure of phase transformation products are controlled, so as to achieve the purpose of refining the structure and improving the strength and toughness of SA283 grade D carbon steel plate sheet.

The carbon content of SA283 grade D carbon steel plate sheet carbon structural steel is about 0.05% - 0.70%, some of which can be as high as 0.90%. Carbon structural steel can be divided into ordinary carbon structural steel and high-quality carbon structural steel. Carbon structural steel is mainly used in railway, bridge and all kinds of construction projects. Carbon structural steel SA283 grade D carbon steel plate sheet can be used to manufacture all kinds of metal components that bear static load and unimportant mechanical parts and general weldments that do not need heat treatment.
