ASTM A270 stainless steel seamless tubes are used for high purity products and equipment in the food, beverage, pharmaceutical, and biotech industries where cleanliness and purity are essential. These tubes are made from austenitic stainless steels like 304 and 316L, which are non-magnetic and have high corrosion resistance.
The ASTM A270 standard specifies the requirements for seamless and welded austenitic and ferritic/austenitic stainless steel sanitary tubing intended for use in the dairy and food industry and having special surface finishes. ASTM A270 stainless steel seamless tubes are manufactured by cold drawing process or by the pilgering process.
The tubes are available in different sizes, wall thicknesses, and finishes such as bright annealed, mechanical polished, and electropolished. The electropolished finish provides a smooth and shiny surface that is easier to clean and prevents bacteria growth.
ASTM A270 stainless steel seamless tubes are also tested for chemical composition, mechanical properties, and corrosion resistance. The tubes must meet the specified requirements for these properties to ensure that they are suitable for use in food and pharmaceutical applications.

Quality and Mechanical Tests:
To assure the highest quality standards, the tubing is subjected to extensive testing and inspection programs that meet or exceed ASTM A270 A1016 A1016M test requirements. Testing includes reverse bend, reverse flattening, and flange tests. Eddy current testing is performed on 100% of the sanitary tube produced.
Heat Treatment (Annealing):
Inline hydrogen bright annealing to 1900°F (1040° C) minimum followed with a rapid quench.
Surface Finishes
SS tube surface finish is 20 µ-in Ra (0.5 µm) ID maximum, 30 µ-in Ra (0.8 µm) OD maximum surface roughness measured per ASME ANSI B46.1 with the profilometer reading at 90 degrees to the lay. Other finishes available upon request.
