The 304l grade is a low-carbon austenitic stainless steel module. A 304L Stainless Steel Tube is designed with a superior composition of nickel and chromium. These tubes showcase excellent corrosion resistance properties across stress-induced setups. The versatile grade of pipes work well in high as well as low temperature setups. These tubes are welded in place following standard welding procedures. We belong to a unique category of 304l stainless steel tube suppliers who provide quality assured products across all our outlets at the most reasonable rates. We also have good ties with the best logistical chains allowing us to deliver products to your doorstep in a short time frame.

The tubes in the 304l grade are generally designed in seamless and welded configurations. A UNS S30403 Seamless Tubing is produced through an extrusion process. Here hot steel billets are passed through the metal grade, ensuring that the tubes are precisely shaped in the correct dimensions. Designed without any welds, the AISI 304L Seamless Tubing has excellent strength and superior load-bearing capacity. These tubes showcase a tensile strength between 500mpa to 700mpa. They have minimum proof stress of 200mpa and can be elongated by a minimum of 45%. The Werkstoff Nr. 1.4306/ 1.4307 Seamless Tubing is slightly expensive due to the material and procedures required in producing the tubing.

This tubing; however, has 20% higher load-bearing capacity and enhanced resistance to corrosion when compared to welded tubing. But the SS 304L Welded Tube is cheaper and requires less processing time. These tubes are produced by rolling sheets or strips, followed by welding them in place using standard welding procedures. We have a vast inventory of items in different shapes and sizes. If you have any queries about our products or want to get a quote on them, contact us for more information.
