ASTM A213 A269 TP316L Austenitic Seamless Bright Annealed Tube
What is the difference between ASTM A269 and A213?
A213 pertains to seamless ferritic and austenitic alloy tubing of minimum wall thickness. Some of the ferritic compositions within the spec are not truly stainless. A-269 is seamless and welded austenitic stainless steel without specifying minimum wall.
316/316L BA Tube Features
It has very good corrosion resistance and can be used for a long time in harsh environments without rust. Secondly， its surface brightness is high， which gives it great advantages in decoration. At the same time， its plasticity is also very good and can be processed and produced according to different requirements. It is worth mentioning that this product is also widely used in the medical field because it will not cause harm to the human body and will not affect medicines.
