310S Stainless Steel Tubing Seamless/Welded Options for Furnace Exhaust and Petrochemical Systems

Products Specification

• Parameters
  • Chemical composition: Ni 19.00 - 22.00%, Cr 24.00 - 26.00%, Si ≤ 1.50%, Mn ≤ 2.00%, C ≤ 0.08%, S ≤ 0.030%, P ≤ 0.035%.
  • Mechanical properties: After solution treatment, the yield strength is ≥ 205MPa, the tensile strength is ≥ 520MPa, the elongation is ≥ 40%, and the hardness is HBS ≤ 187, HRB ≤ 90, HV ≤ 200.
  • Density: 8.0 g/cm³.
  • Size and allowable deviation: The outer diameter ranges from 6 - 2500 mm and can be customized. The allowable deviation of the outer diameter is divided into different levels, such as D1: ±1.5%, minimum ±0.75 mm; D2: ±1.0%, minimum ±0.50 mm.
• Standards: It is produced in accordance with standards such as ASTM A312, ASTM A790, ASME SA213, ASME SA249, ASME SA789, and GB/T14976.
• Advantages
  • High - temperature stability: It can maintain high strength and good toughness at extremely high temperatures, and is not easy to deform or crack.
  • Excellent oxidation resistance: In a high - temperature oxidation environment, it can form a dense oxide film, effectively preventing further oxidation reactions.
  • Good corrosion resistance: It shows good corrosion resistance to various corrosive media such as acids, alkalis, and salts.
  • Good processing performance: It is easy to weld, cut, bend, and form, and can be easily processed into various complex shapes and structures.
  • Long - term reliability: Under the specified use conditions, it has a long service life, reducing the frequency of maintenance and replacement.
• Packaging: The finished 310S stainless - steel pipes are usually carefully packaged to ensure that they are not damaged during transportation and storage. Specific packaging methods may include wrapping with protective materials, bundling, and placing in wooden cases or cartons.
• Applications
  • Petrochemical industry: Used for steam pipelines, furnace tubes, heat exchangers, and other equipment under high - temperature and high - pressure conditions.
  • Energy field: Such as superheater and reheater tube bundles of power station boilers, and some key components of nuclear power plants.
  • Food processing industry: Due to its non - toxicity and harmlessness, it can be used for the pipeline system of high - temperature sterilization equipment.
  • Medical equipment industry: Used for medical equipment such as high - temperature steam sterilizers that need to withstand high - temperature environments.
  • Automobile manufacturing industry: Especially the exhaust systems of high - performance racing cars, which require materials to withstand extremely high temperatures and pressures.
  • Environmental protection equipment industry: Such as the flue pipes of incinerators and the pipes for treating high - temperature corrosive gases.
