Product Description
  • A283 steel coil exhibits excellent work hardening properties during cold forming for its high strength and plasticity. After repeated cold working deformation, the coil can still show similar strength and hardness, with even better ductility and toughness. In addition, due to its good welding performance, the coil can be easily welded into parts of various shapes and sizes, and the welding quality is stable and reliable. A283 steel coils 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.
