A283/Q195 Cold Rolled Steel Plate

ASTM A283 is a carbon steel plate used for general structural purposes. The steel has low and medium tensile strength. The ASTM A283 steel specification covers four structural quality grades of mild steel, grades A, B, C, and D, for general application.

Due to its high strength and good plasticity, A283 steel plate exhibits excellent work hardening properties during cold forming. This means that after repeated cold working deformation, the steel plate can still maintain good strength and hardness, while its ductility and toughness have also been improved. In addition, due to its good welding performance, the plates are easy to weld into parts of various shapes and sizes, and the welding quality is stable and reliable. A283 steel plates are widely used in the manufacturing of various mechanical parts, such as bolts, nuts, pins and other standard parts as well as various non-standard mechanical parts. In addition, they are also used in the manufacture of building structural materials, such as steel bars, steel pipes, steel plates, etc..
