Pipes have good resistance to hot corrosion in multiple environments. These 904L pipes are high-alloy austenitic stainless steel with low carbon content. It contains carbon, chromium, copper, manganese, molybdenum, nickel, phosphorous, sulphur, silicon. It shows good resistance to pitting and crevice corrosion. Also, it shows some properties like good resistance to stress corrosion cracking, intergranular corrosion & good formability, and also weldability.
These grade is usually intended for use under severe corrosive conditions. It has an application which is proved over many years, and it was originally developed to resist corrosion in dilute sulfuric acid. These pipes are standardized and approved for pressure vessel use in several countries. The structural pipe is fully austenitic stainless steel and is less sensitive to precipitation ferrite and sigma phases than the other conventional austenitic grades with high molybdenum content. Because of the relatively high contents of chromium, nickel, molybdenum, and copper have good resistance to general corrosion, particularly in sulfuric and phosphoric conditions.

These Stainless Steel 904L Pipes are used in Shore oil drilling companies, power generation, petrochemicals, gas processing, speciality chemicals. Also, it is used in the pharmaceutical industry, chemical equipment, seawater equipment, heat exchangers, condensers, and pulp and paper industry. The significant inclusion of nickel elements to the alloy of stainless steel 904L makes it possible for the pipes to have an outstanding performance even in elevated settings.
Along with it is a non-magnetic alloy, the Stainless Steel 904L Pipe also exhibits good resistance to stress-related corrosion cracking. Because of the presence of molybdenum element in the alloy is reduces the occurrence of crevice corrosion. Along with this, it is used in applications between moderate to high temperatures.
