ASTM A270 / ASME SA270
Sanitary Tube
ASTM A270 is a standard specification for seamless and welded austenitic and ferritic/austenitic stainless steel sanitary tubing. This standard covers stainless steel tubing used primarily in the dairy, food, pharmaceutical, and other high-purity industries where cleanliness and corrosion resistance are critical.
