904l Stainless Steel pipe


UNS N08904 Seamless Pipe, 904L Stainless Steel Welded Pipes , 1.4539 Hexagonal Pipe, ASTM B677 TP 904L SS Round Pipes

Bhawal Steel Agency is a leading manufacturer that produces different products related to stainless steel. UNS N08904 Pipe, which is also known as 904L tube, falls under the austenitic stainless steel group. It has low carbon content and high molybdenum content. Stainless steel 904L This type of stainless steel tubes have erosion imperviousness to a wide variety of destructive situations. Stainless steel 904L tubes are used in air conditioning refrigeration for machinery on paper, petrochemicals, automobiles, pharmaceuticals and others. 904l maintains a non-magnetic state in all conditions with excellent formability and weldability. SS 904L provides excellent toughness even down to cryogenic temperatures with austenitic structure. The SS 904L pipes have corrosion resistance to various ranges of corrosive environments. Bhawal Steel Agency is a specialist in manufacturing Stainless Steel 904L pipes and tubes. Tubes are available in multiple sizes, shapes, dimensions, grades & thicknesses as per the requirements of the clients.

The austenitic stainless steel 904L is engineered for use in high-temperature environments. It has better resistance to localized attacks such as crevice corrosion and chloride pitting thanks to the addition of molybdenum. It also has excellent resistance to reducing acids, and the addition of copper provides general corrosion resistance to a wide range of concentrations, most commonly sulphuric or acetic acids. The material's high alloying makes it resistant to chloride stress corrosion cracking, although it is still vulnerable. Because of the low carbon content, it is immune to welding sensitization and thus prevents IGC. SS 904L is used in mild environments, namely in chemical industries, gas processings, seawater and building industries, sewer applications, power generation, and many more.
