Duplex 2205 is a nitrogen-enhanced duplex stainless steel that was developed to combat common corrosion problems that were 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 Metalstainless steel, and resistance to chloride stress corrosion cracking approaching that of wrought ferritic stainless steel. Table 1 lists composition and mechanical property limits for two duplex stainless steels of interest herein, as well as for Type 316 stainless steel, all in plate
Friction stir welding was used to produce butt joints on 6 mm thick plates of UNS S32101 lean duplex stainless steel, S32205 duplex stainless steel, and S32750 and S32760 superduplex stainless steels. Fully consolidated joints were achieved, with full penetration, using heat input of 1.37-1.50 kJ/mm. Friction stir welding of duplex and superduplex stainless Friction stir welding was used to produce butt joints on 6 mm thick plates of UNS S32101 lean duplex stainless steel, S32205 duplex stainless steel, and S32750 and S32760 superduplex stainless steels. Fully consolidated joints were achieved, with full penetration, using heat input of 1.37-1.50 kJ/mm. High- Performance Stainless SteelsThe high-performance stainless steels are a family of stainless steels which have distinctly superior corrosion resistance in a wide variety of aggressive environments when compared with the standard stainless steel grades such as Type* 304L, which contains only 18% chromium and 8% nickel (18-8), and Type 316L, which contains
4 Type 2205 Code Plus Two® Duplex Stainless Steel welding. A suitable electrode diameter is 564 332 inch (22.4 mm), depending on base metal thickness, welding position, and accessibility for root-side grinding. Selection of a joint design should accommodate the following guidelines:1. It should be easy to achieve full penetration Metallurgical and Electrochemical Properties of Super Jun 23, 2020 · Duplex stainless steels (DSS) are a special class of ferrous alloys with a balanced ferrite () and austenite () phase microstructure. This dual-phase structure imparts these steels a high NAS 254N (UNS S32053) - Super Austenitic Stainless Steel NAS 254N (SUS 836L, UNS S32053, ASME Code Case 2445-2) is a high corrosion resistance austenitic stainless steel with a high nickel, high chromium, high molybdenum alloy design, and provides excellent corrosion resistance in severe corrosion environments such as high temperature seawater.
NAS74N is a super duplex stainless steel with pitting resistance equivalent (PRE*) number higher than 40, whichprovides not only excellent corrosion resistance but also excellent strength properties. In particular, NAS74N has superior localized corrosion resistance compared with UNS S32205(NAS329J3L, SUS329J3L), and UNS S32506 (NAS64, SUS329J4L).

These steels contain a higher percentage of nickel than t Premature corrosion failure of a 316L stainless steel Apr 01, 2009 · A 316L stainless steel plate subjected to a sulphuric acid environment has failed due to the presence of sigma phase. The sigma phase has been demonstrated to be deleterious to the corrosion performance of the stainless steels by removing chromium and molybdenum from the austenitic matrix.

ASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them. NAS 255 (UNS N08904) - NAS High Corrosion Resistant NAS 255 (UNS N08904, SUS 890L) is an austenitic stainless steel with superior corrosion resistance in comparison with Type 316L. Due to addition of Cu (1.5%), this material displays excellent corrosion resistance against reducing acids such as sulfuric acid and phosphoric acid. It is used in chemical plants and a wide range of other applications.
