Home > Duplex Steel 2205 Flanges
Duplex Steel 2205 flanges are tough, corrosion-resistant components that are a go-to choice in challenging industrial settings. Made from a well-balanced mix of austenitic and ferritic stainless steel, these flanges stand out for their impressive resistance to stress corrosion cracking, pitting, and crevice corrosion. They boast nearly double the strength of standard austenitic stainless steels, which means you can design lighter and more efficient systems. With their sturdy build, precise measurements, and adherence to international standards, they’re perfect for applications that demand durability, safety, and long-lasting performance in harsh conditions.
Duplex Steel 2205 is made up of about 22% chromium, 5–6% nickel, and 3% molybdenum, along with some nitrogen. This unique blend gives it high tensile and yield strength, fantastic toughness, and top-notch corrosion resistance. These flanges are particularly good at resisting stress corrosion cracking and have solid fatigue strength. Thanks to their balanced microstructure, they maintain stable mechanical performance across a wide temperature range, making them ideal for high-pressure and corrosive environments.
