Duplex/Super duplex stainless steel

Sunmire steel has a large inventory of 2304, 2205 and 2507 duplex stainless steel plates available to meet your stringent requirements for corrosion resistance and high strength。

Duplex stainless steel is a type of stainless steel with a relatively high chromium content (between 18% and 28%) and moderate nickel content (between 4.Between 5% and 8%) stainless steel sheet。The nearly equal contents of ferrite and austenite form a balanced (two-phase) microstructure, which, combined with its chemical composition, accounts for its strong corrosion resistance and excellent mechanical properties。Alloys 2304 and 2205 are the most common grades。Chloride stress corrosion cracking resistance is another significant feature of this stainless steel plate。

Super duplex stainless steels have better pitting and gap resistance than ordinary austenitic or duplex stainless steels due to the addition of chromium, molybdenum and nitrogen to this grade。Alloy 2507 is the most common super duplex class。
