Since 2008, there has been a major demand for Duplex Steel ASTM A182 UNS S32205 Pipe Flanges due to its excellent corrosion resistance quality. It resists inter-granular and crevice corrosion. Duplex Steel 2205 Weld Neck Flanges - Citizen MetalsDuplex 2205 is a nitrogen enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels. Duplex describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430 stainless.
Ferrite Control in Duplex Stainless Steel Weld Metal Although it has little influence on yield and tensile strength, controlling the EFN of the weld deposit has a marked effect on ductility BY D. J. KOTECKI Introduction Duplex stainless steels in wrought or cast form, when they reach the user, consist of a microstructure of approxi How to weld Duplex Stainless Steel.ppt [Read-Only]Duplex Stainless Steel Welding methods MMAW Excellent for positional welding or single sided welding where access is limited. DC+ gives best results. A short arc should be used. This gives the best stability and reduces the risk of nitrogen pick-up. The later can lead to pore formation and increase surface oxidation.
North American Stainless . Flat Products Stainless Steel Grade Sheet . 2205 (S32205)/ EN 1.4462 (S31803) Introduction:SS2205 is a duplex stainless steel with a microstructure, when heat treated properly, of nearly equal proportions of austenite and ferrite. This microstructure ensures that SS2205 Product Bulletin High Alloy Stainless Steels September called 2205 and is the most widely used duplex stainless steel. It is produced by most stainless steel producers because it is not protected by any patents. It combines high strength, ductility, and hardness with resistance to corrosion, stress corrosion cracking, and erosion. Because it
2205 Duplex Overview. Duplex 2205 is a nitrogen enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels. Duplex describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430 stainless. Stainless Steel Alloy Duplex 2205, UNS S32205 Duplex 2205, also known as UNS S32205, is a nitrogen-enhanced stainless steel. Users choose Duplex 2205 for its excellent corrosion resistance along with its high strength. It is important to note that Duplex 2205, offers much higher levels of corrosion resistance than most other austenitic stainless steels. Other benefits include:High resistance to pitting and 
martensitic stainless steels. Steels with over 0.20% C often require a post weld heat treatment to soften and toughen the weld. 3.3 AUSTENITIC STAINLESS STEEL The austenitic stainless steels contain 16-26% Cr, 8-24% Ni + Mn, up to 0.40% C and small amounts of a few other elements such as Mo, Ti, Nb (Cb) and Ta.
