Stainless steel flange surface with natural light

Eliminate the modification of the stainless steel flange during the processing, so that the hardness of the stainless steel is restored to below 220 HV, and the plasticity and durability of the stainless steel advance, making the pipe fitting more convenient and safe in the device. Reinforce the stress and intergranular changes in the production process of stainless steel pipe fittings, reduce the intergranular corrosion and stress corrosion of stainless steel, and enhance the corrosion resistance.

Remove the stainless steel due to the magnetic properties of the process, and stabilize the austenite structure. Restores the natural light on the surface of stainless steel data (natural light is different from polished light). Stainless steel pipe fittings are characterized by a special steel type. Because of the presence of alloying elements such as nickel and chromium, the heat treatment has different characteristics from the general steel heat treatment.

Stainless steel has a low thermal conductivity. At normal temperature, the thermal conductivity is only 27% of that of carbon steel. With the advancement of heating temperature, the thermal conductivity of stainless steel is gradually reduced. Therefore, when the stainless steel is heated at a low temperature, the temperature rise process should be carried out slowly. After the austenitic stainless steel is heated to a temperature of about 1100 °C by solid solution, it can be cooled to room temperature according to the onset of strontium carbide, so that the carbon reaches the supersaturation condition, and the stainless steel corrosion resistance function can be advanced.
