Vd-TÜV Alloys | 1.4579 | VdTÜV451

1.4579 (VdTÜV 451) is a duplex stainless steel known for its excellent corrosion resistance, particularly in chloride-rich and acidic environments. Its balanced combination of ferritic and austenitic phases ensures high strength, good toughness, and exceptional resistance to stress corrosion cracking and pitting. This material is widely used in industries such as chemical processing, marine engineering, and offshore technology, where components like heat exchangers, pressure vessels, and piping systems must perform reliably under harsh conditions. 1.4579 also offers good weldability and machinability, making it ideal for precision-engineered components. At Rosswag, this stainless steel is processed through advanced open-die forging and precision machining, delivering customized, high-quality solutions for critical industrial applications.
