904L stainless steel seamless / welded pipe also exhibits good resistance to stress related corrosion cracking. The presence of molybdenum in the alloy reduces the occurrence of crevice corrosion. Along with being used in applications between moderate to high temperatures, the ASTM A312 TP904L is primarily useful for general corrosion applications.
904L stainless steel coil is a non-stabilized austenitic stainless steel material with low carbon content. This high alloy stainless steel is added with copper to improve its resistance to strong reducing acids, such as sulphuric acid.
904L stainless steel combines molybdenum and copper with iron for tremendously increased resistance to reducing acids like sulphuric acid. It stands up extremely well to chlorides in the environment for low pitting and crevice corrosion, as well as stress corrosion cracking.
