The ASTM A249 TP304L grade covers nominal wall thickness low carbon 304L stainless steel pipe. The ASTM A249 TP304L pipe 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 versatile grade of ASTM A249 TP304L Stainless Steel pipes work well across low as well as high temperature applications.
