Product Description
ASTM A269 904L Seamless Austenitic Stainless Steel Tube
904L Stainless Steel Tubing is a low carbon, highly alloyed austenitic grade stainless steel designed for demanding corrosion environments. The low carbon content eliminates intergranular corrosion after welding and heat treatment, while providing excellent resistance to localized attacks including pitting and crevice corrosion.
