ASME SA 249 TP316L Welded Stainless Steel Tubing

ASTM A249 316L ERW Tubes manufacturer

While the SA 249 Tp316l alloy is similar to grade 316, a controlled modification with the content of carbon is what distinguishes it. Often the Stainless Steel 316l Erw is used in areas where welding in specific is deemed to be an important aspect. The reduced carbon content in A249 Tp 316l Stainless Steel Welded Tubing is what makes it resilient to intergranular corrosion.

Pickling and Annealed A249 TP 316L Welded straight and U bend tubes available in exact sizes

Since the ASTM A249 316l Erw Tubing has enhanced immunity against grain boundary carbide precipitation, the material can be used for heavy gauge welded applications. The pipes made from Sa-249 Tp316l material are a popular choice for the marine industry due to several factors. Firstly, the alloy of A249 316l Welded Pipe is resistant to not only seawater and brine, but it is also resistant to compound such as sulphur compounds, phosphoric and acetic acid as well as chloride solutions. Secondly, the corrosion resistance properties of the ASTM A249 Tp 316l to chlorine compound, especially in oxidizing environments are noted by our clients belonging to the marine industry. The ASME SA 249 Tp316l also has the ability to withstand elevated temperature settings without compromising its tensile strength. Furthermore, when used at elevated temperature settings the SA 249 Tp 316l also exhibits properties like a higher creep and stress-to-rupture strength.
