Stainless Steel 904L Flanges

Stainless steel 904l flanges specification

What are stainless steel 904l flanges?

These flanges get manufactured from a low-carbon iron alloy containing chromium, nickel, molybdenum, and copper. Stainless steel 904l flanges get coveted for excellent corrosion resistance, with a pren over 40. These components are widespread in oceanic fittings, chemical processing, pharmaceuticals, and heat-based applications like condenser tubes. Buyers can procure these products for various piping needs, for instance, an aisi 904l reducing flange for connecting pipes of different diameters.


What are the advantages of using 904l stainless steel flanges over other grades?

The best benefits are above-par corrosion tolerance and adaptability to service temperatures up to 450°c. 904l stainless steel flanges tolerate many abrasive agents like dilute sulphuric acid. They exhibit tensile strength (490mpa) and durability because of their chromium content. A sus 904l plate flange works in chemical processing, heat exchangers, and instrumentation.
