Steve Flanges, a top-notch manufacturer and supplier located in Canberra, Australia, has built a solid reputation for crafting high-quality Duplex Steel 2205 Flanges that excel in performance, strength, and resistance to corrosion. These flanges are made from premium duplex stainless steel 2205 and are produced using cutting-edge technology to comply with strict international standards. Steve Flanges provides a diverse selection of Duplex Steel 2205 Flanges in various types, sizes, and pressure ratings to cater to a wide array of industrial requirements. With a strong focus on precision engineering, reliability, and customer satisfaction, the company has established a robust presence in both the Australian and global industrial markets.
Duplex Steel 2205 Flanges primarily consist of chromium (22%), nickel (5–6%), and molybdenum (3%), with added nitrogen to boost strength and resistance. They showcase impressive tensile strength ranging from 620 to 880 MPa and yield strength between 450 and 620 MPa. The unique dual-phase austenitic-ferritic microstructure ensures exceptional mechanical stability and remarkable resistance to pitting, crevice corrosion, and chloride stress-corrosion cracking. These flanges also offer excellent toughness, weldability, and fatigue strength, even in extreme temperature and pressure situations.
