What is Alloy 2205? - Definition from Corrosionpedia

Dec 08,2017 Common Corrosion Test Of 2205 2507 Duplex Stainless Steel#0183;The alloy 2205 is also referred to as Avesta Sheffield 2205,Grade 2205 Duplex or UNS 31803.Corrosionpedia explains Alloy 2205 The alloy 2205 combines the benefits of ferritic and the austenitic steels,and has very high mechanical strength in addition to a very good uniform and pitting corrosion resistance to stress corrosion cracking.The Right Filler Metal to Weld Duplex Stainless SteelThe Right Filler Metal to Weld Duplex Stainless Steel Q We manufacture stainless steel tanks used in various industries and we aren't always informed of service conditions and chemical exposures.We would like to reduce or minimize the number of filler metals we use to cut down on costs and prevent accidental use of the wrong filler metal.Super-duplex steels that resist corrosion in demanding minimum PRE of 42.5.Other 25Cr type duplex stainless steels that are not super-duplex have insufcient corrosion resistance.For example,UNS S31260,has a PRE number of 33.Figure 2 Test samples after pitting corrosion test in accordance with ASTM G48 clearly demonstrate the corrosion resistant capabilities of Sandvik SAF 2507.
