Lastly, 904L stainless steel plate has excellent corrosion resistance and can maintain stable performance in various corrosive environments.

310S stainless steel pipe has good oxidation resistance, corrosion resistance, acid and alkali resistance given its high content of nickel (Ni) and chromium (Cr). The strength is improved due to its solid solution strengthening effect after adding the content of carbon in austenitic stainless steel,. The chemical composition characteristics of austenitic stainless steel are based on chromium and nickel to add molybdenum, tungsten, niobium and titanium, and because of its face-centered cubic structure, it has high strength and creep strength at high temperatures. 310S stainless steel is often used in the manufacture of boiler, steam turbine, industrial furnace and aviation, petrochemical.

317L stainless steel has unique properties and characteristics resulting from its chemical composition. It is composed of a combination of elements such as chromium, nickel, molybdenum, and carbon. Chromium is the main component of 317L stainless steel and makes it highly corrosion-resistant. It forms a protective layer on the metal surface, preventing rust and staining. Chromium also plays an important role in increasing its high-temperature strength. Molybdenum gives it better resistance to pitting corrosion from chloride solutions commonly found in harsh environments such as seawater or chemical processing plants. Carbon content improves hardness but can reduce weldability when controlled improperly. The precise balance between these elements ensures that 317L stainless steel pipe performs better than traditional austenitic grades in high-temperature, corrosive environments.

321 stainless steel pipe has good processing and welding properties, making cutting, bending, welding and other processing operations easy to perform. Besides, it has superior mechanical properties such as tensile strength, flexural strength and elongation, and can meet the requirements of use in various environments. Because 321 stainless steel pipes have excellent corrosion resistance and high temperature performance, they are commonly seen in petroleum, chemical industry, aviation, aerospace. Since the production process of petroleum and chemical industries involves a large amount of corrosive media such as acids, alkalis, and salts, 321 stainless steel pipes can effectively cope with the corrosion of these media and ensure the stable operation of the equipment. 321 stainless steel pipe has become one of the important structural materials in the aviation and aerospace fields.
