  • Hexagonal stainless steel tubing is the standard specification for the welded/ERW and seamless, and heavily cold worked welded austenitic and ferritic stainless steel hexagonal tubing.
  • Our product range for stainless steel hexagonal pipes and tubes include all types such as Seamless, Welded, ERW, and EFW.
  • Stainless steel hexagonal tube is one type of the stainless steel special shaped tube.
  • Stainless Steel Hexagonal Tubing is generally used for structural purposes and applications that range from aesthetic to highly functional – Decoration, construction, hardware, mechanical structure, chemical equipment, pulp and paper, aerospace, nuclear engineering and heat treating industries,boiler, handrail, doors, windows, housewares, kitchenware, etc. Stainless tubing provides good corrosion resistance, weldability, machinability, and can be easily cleaned and sterilized. It has excellent mechanical properties and presents the desirable combination of high strength and good workability. Stainless tube is much lighter than its equivalent bar shape and therefore more practical for use in fabrication where weight is a concern.

Heat Treatment (Annealing) for Stainless Steel Hexagonal Pipes & Tubes as per ASTM standards

304/304L is not hardenable by heat treatment. Cold working increases tensile strength and hardness. Annealing range is between 1850° and 2050°F. Cool rapidly. Water should be used for heavier sections; air for lighter sections. The stress relieving range is between 400° and 750°F

Surface Finishes for Stainless Steel Hexagonal Pipes & Tubes as per ASTM standards

Seamless, Welded, Brushed, Pickled, Solution Annealed and Pickled up to O.D. 219.1mm, Polished Grit 120 – 600, Mirror Polished. Other finishes available upon request.

Flattening Test for Stainless Steel Hexagonal Pipes & Tubes as per ASTM standards

For material heat treated in a continuous furnace flattening tests shall be made on a sufficient number of pipes to constitute 5 % of the lot, but in no case less than 2 lengths of pipe.

Markings for Stainless Steel Hexagonal Pipes & Tubes as per ASTM standards

Bright annealed tubing is line–stenciled with OD, wall, ASTM specifications, size, grade, heat number, production date and time. OD polished tube is marked on one end of each tube with a removable label stating ASTM specification, manufacturer, grade and heat number. Continuous line stencil available on request.

Size (a×b)Thickness



  • Mill test certificates will be issued according to EN10204.3
