What is ASTM A270?
This specification covers grades of seamless， welded， and heavily cold worked austenitic and ferritic/austenitic stainless steel sanitary tubing. Seamless tubes shall be manufactured by a process that does not involve welding at any stage. Welded tubes shall be made using an automated welding process with no addition of filler metal during the welding process.
What is ASTM A270 TP304 tubing?
The ASTM A270 TP304 Tubing has excellent tolerance to oxidative media and showcases enhanced workability and strength. These tubes have good formability and can have threaded， beveled， and plain ends. The A270 Type 304 grade is generally produced in seamless and welded configurations.
The ASTM A270 TP304 Sanitary Stainless Steel Tubes are widely used as structural components and are typically cold wrought. The ASTM A270 TP304 Sanitary Stainless Tubing is frequently used in the food and beverage， medical， pharmaceutical， and biological industries.
Metals have to be selected in accordance with the need for these materials to be hygienic and non-reactive.
