Corrosion resistance and main use environment:
321 stainless steel is Ni Cr Mo austenitic stainless steel. Its properties are very similar to 304, but due to the addition of titanium, it has better grain boundary corrosion resistance and high temperature strength. Due to the addition of metal titanium, it can effectively control the formation of chromium carbide.
321 austenitic stainless steel has good corrosion resistance in the atmosphere and is widely used in petrochemical, electric power, bridge, automobile and other industries. However, the "stainless" of stainless steel is not absolute. Due to the special service environment, stainless steel will also be corroded. Medium concentration, pH value, temperature and other factors will have a great impact on the corrosion resistance of stainless steel. For example, if stainless steel is used for a long time in the sensitization temperature range of 450 ~ 850 ℃, intergranular corrosion will occur. The mechanism is that C combines with CR at the grain boundary to form Cr23C6 and precipitate, which reduces the Cr content at the grain boundary, which is the so-called "poor chromium". Cr element is one of the main elements to inhibit intergranular corrosion. When the Cr content at the grain boundary is less than 12%, the probability of intergranular corrosion will increase.
Application fields: oil and gas industry equipment; Offshore platform, heat exchanger, underwater equipment and fire fighting equipment; Chemical processing industry, utensils and pipelines; Desalination, high-pressure RO equipment and submarine pipeline; Energy industry, such as power plant desulfurization and denitration FGD system, industrial scrubbing system and absorption tower; Mechanical parts (high-strength, corrosion-resistant and wear-resistant parts).
