ASTM A269 TP304 Tube | SA269 TP 304 Stainless steel Seamless Tubing

What is ASTM A269 TP304 tube?

ASTM A269 TP304 alloy consists of nickel and chromium in its chemical composition. Thus, they are a great choice to be used in oxidative media. Even though, they can withstand normal rust, they can get discolored over time. TP304 tubes produced through cold working possess high strength and it has excellent deep drawing properties.

ASTM A269 TP304 Stainless Steel Tube is used in industries like chemical, petrochemical, food processing, pharmaceutical and marine applications. In other words, the tubes are used in applications where corrosion resistance and high temperature performance are crucial. ASTM A269 304 Tubing specification includes sizes ranging from 1/8" to 5" in OD and wall thicknesses between 0.015" and 0.320".

Is A269 TP304 Bright annealed tube same as hot rolled?

Bright annealed and hot rolled SA 269 Grade TP304 Coil Tubing solutions are not the same.

Bright annealing is the process of heating the tube in a controlled atmosphere to prevent oxidation and then rapidly cooling it. Hot rolling involves passing the steel through rollers at high temperatures.
ASTM A269 Gr TP304 Bright Annealed Tubes have a smooth, reflective and shiny surface. Hot rolled tubes have a rougher and scaled surface.
Bright annealing softens the material and improves its ductility and toughness. Hot rolled tubes are left in their as-rolled state.

A269 TP304 Seamless Tube

Advantages of ASTM A269 304 seamless tube

The high chromium and nickel content in ASTM A269 304 provides excellent corrosion resistance.
A269 TP304 Seamless Tubes have good mechanical properties and high tensile strength.
The seamless manufacturing process eliminates the presence of welds which reduces the risk of leakage and increases the overall strength.
They show good formability and weldability.
The seamless ASTM A269 TP 304 Stainless Steel 320 Grit Polish Tubes are durable with low maintenance and longer service life.
These tubes are manufactured according to international quality standards.

Advantages of SA 269 TP 304 welded tube

TP 304 Welded tubes cost less than the seamless variants.
Welded ASTM A269 Grade 304 Condensor & Heater Tubes have good mechanical properties and high tensile strength.
These tubes are suitable for heat exchangers, condensers and general engineering.
Welded tubes are readily available and have shorter lead times which makes them ideal for urgent projects.
They are easier to fabricate into custom shapes and sizes.
Advanced welding techniques are used to ensure consistent and high quality welds in the tubes.
