Stainless steel tube

ASTM A269 904L Seamless austenitic stainless steel tube



904l Stainless Steel Tubing is a low carbon containing highly alloyed austenitic grade stainless steel. The alloy of 904l Stainless Steel Tube is low with regards to the content of carbon, which in turn eliminates the intergranular corrosion after the welding as well as heat treatment. As an alloy, the 904l Tubes have been designed for the strident corrosion conditions. Seamless 904l Tubes has good resistance to localized attack such as pitting and crevice corrosion.
