Austenitic steel ASME SA269 · TP304L

Short Description:

The ASME SA269 TP304L grade covers nominal wall thickness low carbon 304L stainless steel tubing. The ASME SA269 TP304L Tube is designed with an austenite structure that has resistance to general corrosion due to the superior content of nickel and chromium embedded within them.The ASME  SA269 TP304L standard grade covers modules in seamless and welded configurations. The ASME SA269 Grade 304L Seamless Tubing is designed by passing hot steel billets through extruded metal to shape them in correct dimensions.
