Ferritic Stainless Steel Tube - China

Ferritic stainless steel is a type of chromium alloy that has a ferritic structure at elevated and room temperature with body-centered cubic crystal structures.

It has a chemical composition consisting of C≤0.02% and Cr 10.5%~32% and cannot be hardened by heat treatment.

Ferritic stainless steel is used in comprehensive applications with excellent general properties and is taken as a kind of primary nickel-saving stainless steel.

Grades: 409L, 439, 444 Specifications：

- ASTM A268 Standard Specification for Seamless and Welded Ferritic and Martensitic Stainless Steel Tubing for General Service

- JIS G3463 Stainless Steel for Boiler and Heat Exchanger Tubes

- GB/T 30065 Welded ferritic stainless steel tubes for feedwater heater

- GB/T 30066 Welded ferritic stainless steel tubes for heat-exchanger and condenser Features：

- High thermal conductivity

- Low expansion coefficient

- Good antioxidation property

- Excellent stress corrosion resistance The ferritic stainless steel metallurgy has several advantages including its low-cost option for corrosion-resistant stainless steel, being appropriate for several automotive applications including Exhaust System Flanges and Hot Exhaust Gas Oxygen (HEGO) Sensor Bosses, its Antilock Brake System Sensor Rings as well as its Rearview Mirror Mounts.

Magnetic applications for stainless steel include magnetic probes, sensors, armatures, and pole pieces requiring corrosion resistance without plating.

The following tables contain a list of the stainless steel, and other materials, that are available.

For more complete coverage of properties, reference MPIF Standard 35, ASTM B783, ISO 5755, DIN 30910-4, and JIS Z2550, and download the technical information bulletins of interest.

Standard powder metal materials are defined in North America by MPIF Standard 35 and ASTM B783, essentially equivalent standards.

• Business Description: Shanghai T.S. Industrial Co., Ltd focuses on Finned Tubes, Fin Tube, and Finned Pipe used in Heat Exchangers, Boiler Economizers, Coolers, and Heaters.
  
  We supply custom fin tubes and finned pipes in various material configurations that will increase the heat exchangers' heat transfer rate and reduce operating costs.
  
  With an advanced high-frequency resistance welding finned tube production line, an annual production capacity of up to 4000 tons, the specifications of phi 22-273mm finned tube, according to national standards or customer requirements standard production.
  
  The company produces finned tubes (square fin tube, circular finned tube, spiral fin tube, H type finned tube, longitudinal fin tube, corrugated fin tube, spiral serrated fin tube, needle-shaped fin tube, plate-shaped fin tube, inner fin tube) that can be applied to the boiler, air preheater, etc.
  
  Fin tubes or called finned tubes are a major component for various heat recovery systems.
  
  The close connection between the Finning operation and the manufacturing plant allows significant savings in packaging and freight as well as working capital reduction as a result of a “just-in-time” supply chain.
  
  T.S. Industrial Supply and produce to custom requirement finned tubes.
  
  For high-frequency resistance welding finned tube.
  
  The fin, either solid or serrated, in carbon, alloy, or stainless steel is helically wound around the tube and resistance welded.
  
  For Extruded Finned Tube, the Base tube can be carbon steel, alloy Tube, and stainless steel, while the fin can be aluminum and copper alloy.
  
  Typical product, we also produce extruded serrated finned tubes.
  
  For Bending, We can be on the bare tube and also can be over the fin, is performed on-site with custom-designed duplex benders.
  
  In our typical finned tube supply range, we supply both extruded fin tubes and helical welded finned tubes, which are mainly used for the heat transfer industry.
  
  Specific types such as Embedded Fin Tube also called G Type Fin Tube, L Fin Tube, LL Finned Tube, KL Finned Type also call knurled Finned Tube, Extruded Fin Tubes, Extruded Serrated Fin Tube, Square Fin Pipe also call H Fin Tube, Rectangular Fin Pipes also called Double H Fin Tube, Longitudinal Finned Tubes, Studded Tube and Nailhead Pipe, High-Frequency Welded Serrated Fin Tube, High-Frequency Welded Solid Fin Tube.
