AiSi ASTM A554 A312 A270 SS 201 304 304L 309S 316 316L Mirror Polished Square Round Seamless Welded Stainless Steel Tube Pipe
ASTM A554, A312, A270: These are specifications set by the American Society for Testing and Materials (ASTM) for stainless steel tubes and pipes. Each specification defines different requirements for specific applications.
SS 201, 304, 304L, 309S, 316, 316L: These are different grades of stainless steel. Each grade has its own unique chemical composition and properties. For example, 201 and 304 are austenitic stainless steels, while 316 and 316L are commonly used in more corrosive environments.
Mirror Polished: This indicates a specific surface finish applied to the stainless steel tubes and pipes. Mirror polishing involves buffing the surface to a high gloss, resulting in a reflective and smooth finish.
Square, Round, Seamless, Welded: These terms describe the shape and manufacturing method of the stainless steel tubes and pipes. Square and round refer to the cross-sectional shape of the tubes, while seamless and welded describe the construction method. Seamless tubes are manufactured without any welds, while welded tubes are formed by joining two edges together.
ASTM 201: ASTM 201 is a chromium-nickel-manganese austenitic stainless steel. It offers good corrosion resistance, high formability, and excellent mechanical properties. It is commonly used in decorative applications, household appliances, and automotive trim.
310: Stainless steel grade 310 is an austenitic heat-resistant alloy with high chromium and nickel content. It is designed for use in high-temperature environments, such as furnace parts, heat treatment equipment, and exhaust systems.
316L: ASTM 316L is a low carbon version of stainless steel grade 316. It provides enhanced corrosion resistance, particularly against chemical corrosives and acidic environments. It is widely used in marine environments, pharmaceutical equipment, and chemical processing plants.
316: Stainless steel grade 316 is an austenitic chromium-nickel stainless steel with excellent corrosion resistance. It is commonly used in applications that require resistance to corrosion and high temperatures, such as chemical processing, food industry, and marine equipment.
430: Stainless steel grade 430 is a ferritic stainless steel with good corrosion resistance. It is often used in decorative applications, household appliances, and automotive trim. However, it has lower corrosion resistance compared to austenitic stainless steels.
304: ASTM 304 is an austenitic stainless steel with excellent corrosion resistance, good formability, and high strength. It is widely used in various industries, including food processing, chemical processing, and architectural applications.
