ASTM A269 Stainless Steel Tube

ASTM A269 stainless steel tube is an austenitic stainless steel tube for general corrosion resistance and low or high temperature service. Including ASTM A269 seamless stainless tube and ASTM A269 welded stainless tube. ASTM A269 tubing specifications most commonly used stainless steel pipe grades are TP304, TP304L, TP304LN, TP316, TP316L, TP316LN, TP317, TP321, TP347, TP347H, S31254, N08367, N08904. These grades are selected on the basis of their chemical composition, mechanical properties and corrosion resistance.

 

ASTM A269 Standard Specification

ASTM A269 standard specifies the requirements for chemical composition, mechanical properties, coatings, and marking of pipes. These requirements ensure the reliability and durability of ASME SA269 stainless steel tubes. A269 tubing is produced using different methods, including seamless and welding techniques. A269 seamless tube is made by perforating a billet or bar and then drawing it onto a mandrel to form the desired shape and size. Welded stainless steel pipes (EFW, ERW, SAW) are made by rolling a steel strip into a pipe and then welding the edges together using a high-frequency resistance welding process.
