The outer diameter of the hot-rolled seamless pipe is generally larger than 32mm, and the wall thickness is 2.5-75mm. The diameter of the cold-rolled seamless pipe can be 6mm, the wall thickness can be 0.25mm, the outer diameter of the thin-walled pipe can be 5mm, and the wall thickness is less than 0.25mm. The size accuracy of the cold-rolled seamless pipe is higher than that of the hot-rolled seamless pipe, A283 Gr A CS steel carbon plate.
20# steel plate is a high-quality low-carbon carbon steel plate, cold extruded, carburized and hardened steel. A283 Gr A CS steel carbon plate, 20# steel has low strength, good toughness, plasticity and weldability. The tensile strength is 253-500MPa, and the elongation is ≥24%. 20# steel performance is basically similar to 15# steel, but the strength is slightly higher.The cold-drawing or normalizing state of the cutting process is better than the annealing state. 20# steel is used to manufacture various mechanical parts with high toughness under hot rolling or normalizing state, which require high toughness.
