ASTM A269 stainless steel tube | SA 269 SMLS tubing manufacturer

What is ASTM A269 standard?

ASTM A269 specification is used for general corrosion resisting and low or high temperature service. These tubes have high durability and they can withstand elevated temperatures without losing strength. The A269 Tubings are cost effective because of their low maintenance and long service life. They are available in heat treated conditions and comes with various finishes.

The ASTM A269 Standard is used in harsh environments with high pressure like hydraulic systems. They can be found in industries like chemical processing, oil & gas exploration, food & beverage and you can customize it as per your project requirements.

ASTM A269 annealed pickled vs A269 bright annealed Tube

Annealed pickled ASTM A269 Stainless Steel Tube undergoes a pickling process to remove oxides and surface impurities. Whereas, for bright annealing, the tubes are passed through furnace to prevent surface oxidation in a controlled atmosphere.
Annealed pickled tubes have a rough surface finish whereas bright annealed tubes have a smooth and glossy finish.
Annealed pickled 304 ASTM A269 Tubing is used where appearance is not a factor whereas bright annealed tubes are used for aesthetic applications.

How does A269 Material annealing affect hardness?

During annealing, the crystal structure of the material undergoes recrystallization. This leads to the formation of a more uniform and refined grain structure. This can cause defects in the ASTM A269 Tubing Specifications material which decreases its hardness.

What is the difference between annealing and tempering of ASTM A269 seamless stainless steel tubing?

Annealing involves heating A269 Stainless Steel Tubing to a specified temperature before cooling it at a slow and controlled rate. For tempering, the material is heated below its critical temperature in inert or vaccum atmosphere.
Annealing on ASTM A269 Tubing Sizes creates a softer material that has high workability. Tempering reduces the brittleness and the material can be used in different industrial applications.
Annealing requires the metal to be heated to a specific temperature whereas tempering means heating ASTM A269 Seamless Stainless Steel Tubing gradually to prevent cracks.
