Duplex stainless steel offers exceptional resistance to corrosion and high mechanical strength. The superior corrosion resistance of duplex stainless steel ensures significantly longer operational uptime compared to carbon and conventional stainless steels. Its mechanical strength allows for lighter constructions, compact system designs, and reduced welding, making it an ideal choice for demanding industrial applications.
At AstroForge Fitting Industries, we specialize in providing top-quality duplex stainless steel fittings, including pipe fittings, forged fittings, buttweld fittings, and flanges. Our extensive stock range and expertise in duplex and super duplex grades ensure that we meet the diverse needs of industries around the world.
