2507

2507 is a high-performance super duplex stainless steel composed of ferrite and austenite dual-phase structure. It combines high strength, excellent toughness and outstanding resistance to pitting, crevice corrosion and chloride stress corrosion cracking. With high chromium, molybdenum and nitrogen content, it performs excellently in harsh environments such as seawater, brine and strong acid media. It is widely used in desalination, marine engineering, petrochemical, flue gas desulfurization and

S32205

2205 is a standard duplex stainless steel with balanced ferrite and austenite microstructure. It integrates high mechanical strength, good toughness and excellent local corrosion resistance. Benefiting from reasonable chromium, nickel, molybdenum and nitrogen alloy design, it shows strong resistance to pitting, crevice corrosion and chloride stress corrosion cracking. It has stable mechanical properties, good weldability and cost-effective performance, widely used in petrochemical, sewage treatm
