A Guide to Duplex Stainless Steel What is It? - Unified

Duplex stainless steels get their name from their two-phase microstructure. While exact ratios vary by grade, most duplex steels have a structure that is roughly 50-percent austenite and 50-percent ferrite. This gives duplex stainless many of the perks of austenitic and ferritic families of steel while also minimizing the weaknesses. A Guide to Duplex Stainless Steel What is It? - Unified These duplex stainless steels share many similarities with the modern alloys in production today in particular, Duplex 2205 (UNS S21803/32205). Developed in the mid-1970s, this alloy is still popular today providing corrosion resistance superior to common austenitic stainless steel grades , such as 304 (UNS S30400), 316 (UNS S31600), and

Duplex Duplex stainless DUPLEX steel welding. Best Duplex stainless-steel-world.net STAINLESS STEEL WORLD NOVEMBER 200747 section sizes or heavy sections with very low heat input. The high alloy content and the presence of a ferritic matrix render DSS susceptible to embrittlement and loss of mechanical properties, particularly toughness, through pro-longed exposure at elevated temper-atures.

Duplex Stainless Steel Benefits and Use Special Piping

The most used duplex stainless steels are the 2205 (22% Chromium, 5% Nickel) and the 2507 (25% Chromium, 7% Nickel); 2507 is known as super duplex due to its higher resistance to corrosion. The advantage of combining ferritic and austenitic grades is that the resultant metal has a metallurgical structure that consists of two phases and Duplex Stainless Steel Pipe ASTM A789 / ASTM A790 / ASTM Duplex stainless steels are in most cases, tougher than ferritic stainless steels. Strengths of duplex stainless steels can in some cases be double that for austenitic stainless steels. The duplex stainless steels are considered resistant to stress corrosion cracking, they are not as resistant to this form of attack as ferritic stainless steels.
