Super austenitic stainless steel Alloy 904L is intended for moderate to high corrosion resistance in various process conditions. High levels of nickel and chromium, as well as the additions of molybdenum and copper, guarantee good to outstanding corrosion resistance. Initially designed to tolerate conditions with diluted sulfuric acid, alloy 904L. It also provides good resistance to the majority of organic acids and other inorganic acids, such as hot phosphoric acid. One of the few stainless steels that, at temperatures up to 95°F (35°C), gives full resistance in such situations within the concentration range of 0 to 100% is 904L, which was initially created to survive settings containing dilute sulfuric acid.

Additionally, 904L has good resistance to several other inorganic acids, including phosphoric acid and most organic acids. Sulphide stress cracking (SSC) can occur in conventional stainless steels like 304L and 316L under specific circumstances. With an increase in nickel and molybdenum content, SSC resistance rises. As a result, austenitic stainless steels with superior performance, such as 904L, have excellent resistance to SSC (Sulphide stress cracking).

What exactly are SS 904L Flanges?
Stainless steel flange, abbreviated as SS flange, refers to stainless steel flanges. ASTM A182 Grade F304/L and F316/L are common material standards and grades, with pressure ratings ranging from Class 150, 300, 600, and up to 2500.

What are the applications of SS 904L flanges?
SS 904L Flanges is a device used to connect two pipes. It can also assist in connecting the pipe to a choke, valve, tee, or other piping system equipment.

Why should I use SS 904L Flanges?
Because of the high chromium concentrations, nickel, molybdenum, and copper, stainless steel 904L pipe fittings and 904L flanges exhibit greater resistance to pitting and crevice corrosion, as well as a general decrease in reducing acids.
