ASTM A270
ASTM A270 specifies the requirements for stainless steel sanitary tubing used primarily in the healthcare, pharmaceutical, and food industries. The tubing must be made from austenitic stainless steels known for corrosion resistance, durability, and cleanliness. Common materials under ASTM A270 include:
These materials ensure hygienic, corrosion-resistant, and mechanically robust tubes suitable for sterile and clean environments.
