SUS 310S Stainless Steel Seamless Tubing , Thin Wall Steel Tubing For Processing Plant
SUS 310S is a Japanese designation for stainless steel grade 310S, which is commonly used for various applications, including pipes. Here is a description of SUS 310S stainless steel pipes:
Stainless Steel Grade: SUS 310S is an austenitic stainless steel grade that offers excellent high-temperature strength and oxidation resistance. It belongs to the 300 series stainless steels, which are known for their high chromium and nickel content.
Heat Resistance: SUS 310S stainless steel pipes exhibit exceptional heat resistance, making them suitable for applications involving elevated temperatures. They can withstand temperatures up to 1100°C (2012°F) in continuous service and up to 1150°C (2102°F) in intermittent service.
Corrosion Resistance: SUS 310S offers good corrosion resistance in a wide range of environments, particularly in oxidizing and mildly reducing conditions. It is resistant to atmospheric corrosion, as well as to many corrosive chemicals and gases encountered in industrial applications.
High-Temperature Strength: SUS 310S stainless steel pipes retain their strength and mechanical properties even at high temperatures. This makes them suitable for applications in heat exchangers, furnaces, kilns, and other equipment operating under high-temperature conditions.
Weldability: SUS 310S stainless steel pipes are readily weldable using common welding techniques. It is important to use appropriate filler materials and follow recommended welding procedures to maintain the corrosion resistance and mechanical properties of the material.
Applications: SUS 310S stainless steel pipes find applications in various industries, including petrochemical, chemical processing, power generation, and heat treatment. They are used in furnace components, radiant tubes, heat exchangers, and other high-temperature equipment requiring excellent heat resistance and corrosion resistance.
It is important to note that SUS 310S is equivalent to the international standard AISI 310S or ASTM A312/A213 grades 310S. When selecting stainless steel pipes, it is advisable to consult with manufacturers or suppliers who can provide specific information on the product's compliance with SUS 310S or other relevant standards and its suitability for your specific application requirements.
According to different uses, the requirements for various properties of stainless steel pipes are different, such as acid and alkali corrosion resistance, intergranular corrosion resistance and stress corrosion cracking performance, pitting resistance, climate corrosion resistance, high temperature and oxidation resistance. For use in high temperature environment, it is also required to have satisfactory high temperature persistent strength, durable plasticity, creep resistance and aging stability.
Stainless steel pipe is mainly used for auxiliary exchanger pipe, water heater pipe, main pipe, cooling water pipe and other pipes. Electricity, as the basis of national economic development, national economy and people's livelihood. The inner wall of the stainless steel pipe is smooth, the water transmission resistance is small, can withstand the erosion of high water flow rate, after solution treatment, the mechanical properties of the pipe and the matrix, the corrosion resistance is basically the same, the performance is excellent, and it is widely used in heaters, boilers, heat exchangers, condensers.
China's production of seamless stainless steel pipes is mainly concentrated in Inner Mongolia Baotou Steel, Shanghai Five Steel (Group) Co., LTD., Great Wall Special Steel Co., LTD., Dalian Steel Plant, Fushun Steel Plant, Daye Special Steel Co., LTD., Chengdu Seamless Steel Plant, although the specific process equipment of each production facility is different. However, its production process is mainly divided into hot-rolled seamless stainless steel pipe production process, cold-working seamless stainless steel pipe production process and hot-extruded seamless stainless steel pipe production process.
