2507 duplex stainless steel pipes are a high-performance material combining the best properties of austenitic and ferritic stainless steels. With excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking, 2507 pipes are widely used in industries requiring exceptional strength and corrosion resistance. Chinese factories are major suppliers of 2507 duplex pipes, offering competitive prices, large production capacities, and fast delivery for global customers.
Overview of 2507 Duplex Stainless Steel
2507 duplex stainless steel, also known as UNS S32750, contains approximately 25% chromium, 7% nickel, and 4% molybdenum. The high alloy content ensures outstanding corrosion resistance in harsh environments, especially in seawater and aggressive chemical processing conditions. It also offers about twice the strength of common stainless steels like 304 or 316, making it suitable for high-pressure systems.
