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.
In summary, ASTM A270 stainless steel seamless tubes are an important component in the manufacturing of high purity products and equipment in the food, beverage, pharmaceutical, and biotech industries. They are made from non-magnetic austenitic stainless steel, have high corrosion resistance, and are available in different sizes and finishes to meet specific application requirements.
ASTM A270 is a standard specification for seamless and welded austenitic and ferritic/austenitic stainless steel sanitary tubing intended for use in the dairy and food industry and also for other industrial applications, including chemical and pharmaceutical industries. The ASTM A270 specification covers grades of seamless, welded, and heavily cold worked austenitic and ferritic/austenitic stainless steel sanitary tubing intended for use in the dairy and food industry and also for other industrial applications.
The ASTM A270 stainless steel seamless tube is commonly used in chemical machinery applications where high corrosion resistance and strength are required. The seamless tube provides excellent chemical and mechanical properties, making it suitable for use in harsh environments. The ASTM A270 stainless steel seamless tube is made from austenitic stainless steel and is available in various sizes, পুরুত্ব, and types.
Some common types of ASTM A270 stainless steel seamless tube include:
1. Type 304/304L: This is the most commonly used stainless steel seamless tube, which is suitable for most chemical machinery applications.
2. Type 316/316L: This type of stainless steel seamless tube is highly resistant to corrosion and is ideal for use in harsh environments.
3. Type 321: This type of stainless steel seamless tube contains titanium, which provides additional strength and corrosion resistance.
In conclusion, the ASTM A270 stainless steel seamless tube is an excellent choice for chemical machinery applications where high corrosion resistance and strength are required. Its superior chemical and mechanical properties make it suitable for use in harsh environments.

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.
