The production process of color steel plate is not very simple, it needs a lot of steps to complete, we now have very high requirements for color steel plate, so we also need high requirements for the production process of productsAfter tempering twice, it must be cooled to room temperature. The minimum tempering temperature of color steel gusset plate is 180 ℃ (suitable for small parts). Keep warm for at least two hours. Note 1: tempering at 250 ℃ is recommended for the best combination of toughness, hardness and corrosion resistance. Note 2: the combination of too high austenitizing temperature and too low tempering temperature < 250 ℃ should be avoided to avoid too much stress in the die. The dimension deformation of S136, the temperature of quenching and tempering, different kinds of stoves and quenching media will affect the change of die size. Die size and geometry are equally important. During the processing of color steel gusset plate die, the processing capacity should be reserved to make up for the dimensional deformation after heat treatment. It is suggested to reserve 0.15% between rough machining and semi finish machining as the processing reservation index of S136. Due to the low impurity content of S136, it is very suitable for photolithography. Because of the excellent corrosion resistance of S136, a special photolithography procedure must be used. This feature has also been widely known by photolithography companies. The polishing, quenching and tempering of S136 have excellent polishing properties. However, the polishing technique is a little different from that of other AsAb steels. The main principle is to adopt multiple procedures in fine grinding and polishing, and do not polish on very rough surfaces. But when polishing, after the scratch left by the previous polishing procedure is removed, the polishing must be stopped immediately.
