Hot Rolled Stainless Steel Sheet 30mm SUS321 NO.1 Finish 1500x6000mm

Hot Rolled Stainless Steel Sheet 20mm 30mm NO.1 Finish 1500x6000mm

321 austenitic stainless steel has good corrosion resistance in the atmosphere and is widely used in petrochemical, electric power, bridge, automobile and other industries [1]. 321 austenitic stainless steel has good corrosion resistance in the atmosphere and is widely used in petrochemical, electric power, bridge, automobile and other industries [1]. But stainless steel "rust" is not absolute, due to the special service environment, stainless steel will also occur corrosion. Medium concentration, pH value, temperature and other factors will have a greater impact on the corrosion resistance of stainless steel. For example, in 450~850℃ sensitization temperature range of long-term use, stainless steel will occur intergranular corrosion. Its mechanism is the combination of C and Cr at the grain boundary, forming Cr23C6 and precipitation, so that the content of Cr at the grain boundary is reduced, which is the so-called "poor chromium". Cr is one of the main elements to inhibit intergranular corrosion. When the content of Cr at grain boundary is less than 12%, the probability of intergranular corrosion will increase.
