SS ASME SA269 / ASTM A269 TP316L Seamless Tube Bright Annealing

What is A269 TP316L ?

ASTM A269 Tp316L is a grade of seamless and welded austenitic steel with nominal wall thickness that is designed with 316 austenitic stainless steel. The ASTM A269 TP316L Tube is composed of an outstanding content of chromium, nickel, and molybdenum.

Characteristics

ASTM A269 tubing, made of grades TP304 and TP316 as well as their low carbon version TP304L and TP316L, exhibits good corrosion resistance in atmospheric industrial and marine environments as well as some oxidizing chemical environments. Especially, TP316 & TP316L offer enhanced resistance to pitting corrosion in chloride solution. The low carbon version TP304L or TP316L reduces sensitization significantly and provides much better welding performance. The tubing has outstanding impact toughness at low or cryogenic temperatures. It maintains long life span at elevated temperatures and under other severe conditions.

Applications

The ASTM A269 tubing are widely used in instrumentation piping to connect various piping, valves, instruments and apparatuses, or to measuring equipment. They may be used for high purity gas piping, fine chemical engineering, sampling & analysis system, hydraulic line, chemical and petrochemical process control, coal processing, as well as automotive engineering. Especially, grades TP304, TP304L, TP316 and TP316L of ASTM A269 are listed and endorsed by ASME B31.3 – process piping.
