Supply 1020 cold rolled steel plate, ultra-thin 1020 cold rolled steel plate

The strength is slightly higher than that of steel, rarely quenched, and has no temper brittleness. It has high cold deformation plasticity and is generally used for bending, rolling, flanging and hammer arching. It has good welding performance in arc welding and contact welding. The thickness is small during gas welding and cracks are prone to occur on parts with strict appearance requirements or complex shapes. The cold-drawn or normalized state has better machinability than the annealed state, and is generally used to manufacture materials with low stress but high toughness requirements. This steel is high-quality low-carbon carbon steel, cold extruded, carburized and hardened steel. This steel has low strength but good toughness, plasticity and weldability. The tensile strength is 3~, and the elongation is 3~.
Normalizing can promote the spheroidization of the steel, refine the large proeutectoid ferrite, and improve the cutting performance of the blank smaller than B.
The process route of the steel mold parts is: blanking rrr forging die blank rrr annealing rrr mechanical roughing rrr cold extrusion forming rrr recrystallization annealing rrr mechanical finishing rrr carburizing rrr quenching and tempering rrr grinding and polishing rrr assembly .
