Product Details
2205 stainless steel (UNS S32205 formerly known as UNS S31803 and commonly known as “alloy 2205”) has a mixed microstructure of austenite and ferrite, and is a two-phase alloy based on the Fe-Cr-Ni series. Alloy 2205 material has lower nickel and molybdenum contents than austenitic stainless steel and have similar corrosion resistance. Because the price of Ni and Mo is relatively high, duplex stainless steel 2205 is often regarded as a cost-effective alternative to austenitic stainless steel.
Stainless Steel 2507 Duplex is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel. This alloy is designed for applications which require exceptional strength and corrosion resistance; examples include applications in chemical processing, petrochemical, and seawater equipment. The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity and a low coefficient of thermal expansion. The high chromium, molybdenum, and nickel levels provide excellent resistance to pitting, crevice, and general corrosion.
Application: Construction field, ships building industry, petroleum, chemical industries, war and electricity industries, food processing and medical industry, boiler heat ex changer, machinery and hardware fields, etc.
