As an austenitic stainless steel material containing titanium stabilizing elements, 321 stainless steel plate has shown excellent comprehensive advantages in the industrial field by virtue of its core alloy ratio of 18% chromium and 8% nickel and the precise combination of titanium elements. The addition of titanium elements not only effectively inhibits the precipitation of chromium carbide at the grain boundary and significantly improves the resistance to grain boundary corrosion, but also gives the material excellent anti-sensitization performance in the high temperature range of 500-800℃, making it the preferred material for the manufacture of open-air equipment in harsh environments such as the chemical industry, coal mining, and petroleum refining.
321 stainless steel is particularly outstanding in high temperature stability. Its high temperature stress fracture performance and anti-creep performance exceed conventional 304 stainless steel. It can still maintain high strength and structural stability under continuous high temperature conditions. It is particularly suitable for the manufacture of heat exchanger pipes, high temperature piping systems, and complex heat-resistant parts that cannot be heat treated. For the corrosive environment of oxidizing media, 321 stainless steel plates show super tolerance in organic acid and inorganic acid media of different concentrations and temperatures, and can be widely used in key parts such as acid storage tank linings, wear-resistant transmission pipelines, and chemical reaction devices.
Compared with 316L stainless steel, 321 material has significant advantages in high temperature strength and thermal stability; compared with traditional 304 stainless steel, its intergranular corrosion resistance is significantly improved after titanium stabilization treatment, which is especially suitable for welded parts and field equipment exposed to corrosive atmosphere for a long time. This series of characteristics makes 321 stainless steel plate an industrial solution that takes into account corrosion resistance, high temperature mechanical properties and processing feasibility, and continues to serve the core equipment manufacturing in the fields of energy mining, chemical manufacturing, and building materials production.
304 stainless steel plate has beautiful surface and diverse usage possibilities
Good corrosion resistance, longer lasting than ordinary steel
High strength, so thin plates can be used
High temperature oxidation resistance and high strength, so it can resist fire
Processing at room temperature, that is, easy plastic processing
Since no surface treatment is required, it is simple and easy to maintain
Clean and smooth
Good welding performance.
