ASTM A269 TP304L Tube
What is ASTM A269 TP304L?
ASTM A269 TP304L is a standard for the low carbon version of the 304 grade ss material. They are intended for general corrosion resisting applications due to the presence of high chromium and nickel content. The material shows high strength and thus, they are capable of resisting high mechanical stress.
ASTM A269 TP304L Tube shows good resistance to high temperature and pressure too. The lower carbon content makes it more resistant to sensitization which is a condition that can occur during welding. Herein, carbides can form and reduce the corrosion resistance properties of the material. The OD of the ASME SA 269 304L Coil Tubing ranges from 1/8" to 5" and wall thicknesses are between 0.015" to 0.320".

Difference between SA 269 TP 304L seamless and welded tube
- The seamless ASTM A269 Grade 304L Heater Tubes are manufactured without any welding seams. They are formed by piercing a solid billet and then rolling it into a tube shape. Welded tubes are manufactured by welding together two edges of a flat strip or a coil. The welding process can be carried out using different techniques like TIG or ERW.
- Seamless tubes are more reliable and suitable for high pressure and temperature applications. They have a smoother interior surface, which reduces the risk of corrosion and improves fluid flow. ASTM A269 304L Welded Tube is more cost effective and suitable for less critical applications.

How is annealing done for A269 TP304L bright annealed tube?
Annealing is a crucial process wherein the ASTM A269 TP 304L Stainless Steel Tube is heated to a specific temperature and then rapidly cooled to achieve the desired properties and surface finish. The process is carried out in controlled atmospheres to prevent oxidation and ensure a smooth and reflective surface. The process includes the following steps:
- The ASTM A269 Grade TP304L Bright Annealed Tubes are placed in a furnace and heated to the annealing temperature.
- They are held at the annealing temperature for a specific period to allow for uniform heat distribution.
- Then the tubes are rapidly cooled to room temperature to prevent the formation of large grains and achieve a fine and uniform grain structure.
SA 269 Grade TP304L ERW Tubes and ASTM A269 304L Welded Tube are built-in various specifications ranging from 1/8” to 30” in size

What is stronger SA 269 Gr 304L square tube or ASTM A269 304L round tubing?
Round shaped SA 269 Gr 304L Heat Exchanger Tubes are stronger than the square ones. This is because:
- Round tubes are solid, rigid and their strength remains distributed in all directions.
- They are easier to control during bending due to the even strength distribution format.
- Round SA 269 Grade TP304L ERW Tubes are lightweight with higher weight bearing capacity. This is because the round shape has no corners and hence, fewer pressure points.
