Stainless Steel 904L Pipe

What is Stainless Steel 904L Pipe ?

904L is a highly alloyed, low-carbon, non-stabilized austenitic stainless steel. Copper is added to the mix, which gives stainless steel 904L pipe excellent resistance to strong reducing acids like sulfuric acid. It also offers outstanding strength, toughness, and high resistance to corrosion and cracking. This makes it ideal for harsh environments such as marine, chemical, and fertilizer industries. Parag Metals is a leading supplier of stainless steel 904L pipe and has carved an esteemed position in the metal industry by making persistent efforts to cater to the clients with premium quality stainless steel 904L pipe.

904L pipe comes in different forms like round, square, oval, and rectangular. End finishes are available in plain or beveled types, based on use. This alloy works well in industries such as oil and gas, power plants, pulp and paper, and seawater treatment. It is a reliable option available for heat exchangers, condensers, and process equipment due to its strong resistance to stress cracking and chloride corrosion. The 904L pipe is known for its exceptional weldability, long lifespan, and low maintenance requirements.
