Overview

Our Duplex and Super Duplex Forged Fittings are manufactured using high-quality raw materials and precision forging techniques, ensuring dimensional accuracy, long service life, and leak-proof performance. With balanced microstructure (austenite and ferrite), Duplex and Super Duplex grades provide twice the strength of standard stainless steel while maintaining impressive corrosion resistance in chloride-rich and acidic environments.

Available in grades such as Duplex 31803/32205 and Super Duplex S32750/S32760, Steelvron offers a wide range of forged fittings including elbows, tees, couplings, crosses, unions, bushings, plugs, and custom designs as per client specifications. Each fitting is tested to meet international standards such as ASTM, ASME, DIN, and EN, making them suitable for demanding industrial applications.
