1.4462 Forged Steel Pipe Fitting Duplex 2205 Threaded Coupling for Industrial Machinery

The 1.4462 Duplex 2205 Forged Stainless Steel Threaded Coupling is a high-performance connector engineered for demanding industrial applications. Made from duplex stainless steel (UNS S32205/S31803), it combines exceptional strength, corrosion resistance, and long-term durability for harsh environments such as oil and gas, chemical processing, and marine systems. The threaded design provides secure, leak-tight assembly, while the forged construction enhances structural integrity under high pressure and temperature.

Duplex 2205’s dual-phase microstructure (austenitic + ferritic) offers outstanding stress-corrosion-cracking resistance and delivers twice the yield strength of standard stainless steels. Grade 1.4462 also provides excellent weldability and extended service life, reducing maintenance requirements. Precision-machined threads comply with international standards (ASME, DIN), ensuring compatibility with existing pipelines. This coupling is a reliable choice for industries requiring superior safety, efficiency, and corrosion protection in fluid-handling systems.

Forged Steel: Grades, Parts, Shafts & When to Choose Forging

Industry News 2026-05-25

What Is Forged Steel? Forged steel is steel that has been shaped by applying compressive force — hammer blows, press tonnage, or die pressure — while the metal is at an elevated temperature, typically between 1,100°C and 1,250°C (2,000°F–2,300°F) for hot forging. The mechanical working breaks up ca...
