ASTM A269 TP347 Stainless Steel Tube Bright Annealed or Polished
Specifications
ASTM A269 TP347 is a specification for seamless and welded stainless steel tubing used in general corrosion-resisting and low-to-high temperature services. The specification includes requirements for chemical composition, mechanical properties, dimensional tolerances, and testing for tubes typically ranging from (1/4) in. ((6.4) mm) in inside diameter and heavier in thickness. Key properties include its columbium-stabilized austenitic stainless steel composition, making it suitable for high-temperature applications.
