310S Stainless Steel Overview:

310S stainless steel is austenitic chromium-nickel stainless steel. It has good oxidation resistance and corrosion resistance of 310S stainless steel. Because of the higher percentage of chromium and nickel, it has much better creep strength and can continue to operate at high temperatures. Good high temperature resistance. Due to the high content of nickel (Ni) and chromium (Cr), it has good oxidation resistance, corrosion resistance, acid and alkali resistance, and high temperature resistance. High temperature resistant steel pipes are specially used to manufacture electric furnace tubes. The austenitic stainless steel adds carbon After the content, the strength is improved due to its solid solution strengthening effect. The chemical composition of austenitic stainless steel is based on chromium and nickel with the addition of elements such as molybdenum, tungsten, niobium, and titanium. Because of its face-centered cubic structure, Therefore, it has high strength and creep strength at high temperature.

As an important material in the aerospace and chemical industries, 310S heat-resistant stainless steel is widely used in high-temperature environments. High-temperature oxidation is the most common and most important form of corrosion damage at high temperatures. Therefore, the research and development of new materials with high-temperature oxidation resistance has far-reaching significance for my country's aviation industry, chemical industry and national defense.
