lean duplex stainless steel cold-formed hollow sections [5, 6], are used to assess the applicability of the current cross-section classification limits of Eurocode 3:Part 1.4 2101 Duplex Stainless Plate Specialty Steel Co.2101 Duplex is a lean-alloyed duplex stainless grade that has approximately equal parts Austenite and Ferrite. This grade of stainless combines high chromium, nitrogen, molybdenum, and low nickel to provide improved resistance to corrosion and high mechanical strength. 2101 Duplex offers good resistance to Stress Corrosion Cracking (SCC) a form of corrosion found in hostile environments.
Stainless Steels ASC2250® LDX Lean Duplex, High Strength, Bearing-Fit, Stainless Shaft. ASC2250 LDX is a lean duplex stainless steel shafting that exhibits equal parts Austenite and Ferrite. This particular grade will outperform most austenitic grades in a host of critical service applications. Article:Duplex Stainless Steels - A Simplified GuideDuplex Stainless Steels - A Simplified Guide Duplex Stainless Steels - A Simple Guide . Duplex stainless steels are becoming more common. They are being offered by all the major stainless steel mills for a number of reasons:Higher strength leading to weight saving ; Greater corrosion resistance particularly stress corrosion cracking Axial slenderness limits for duplex and lean duplex Sep 01, 2020 · The most slender duplex and lean duplex circular specimens (i.e. D-C500 and L-C540 respectively) were among the largest duplex/lean duplex stainless steel sections tested to date and their section slenderness values (d/t) were very close to the maximum permitted value of 0.31E/f y currently in use by international design standards such as AISC
Keywords:Lean Duplex Stainless Steel, ATI 2102®, S82011, Pipe ABSTRACT ATI 2102® alloy (UNS S82011) is a recently developed, lean duplex stainless steel (LDSS). With a composition containing approximately 21.5% Cr and 1.5% Ni, ATI 2102 LDSS has strength and corrosion resistance superior to that of Type 304L stainless steel.

Development of lean duplexes While lean duplex stainless steel (DSS) is considered to be a modern grade by some, in fact a lean duplex grade - i.e. DSS grade without Mo and restricted Ni, addition was already developed in France before the 1960s (URF1 21Cr%1,5Cu). Shortly afterwards Ugine developed grade AF20, a 20% Cr DSS Material properties of cold-formed lean duplex stainless The material properties of high strength cold-formed lean duplex stainless steel square and rectangular hollow sections were determined. Tensile coupons in the flat portions and corners of each Structural performance of cold-formed lean duplex This section of the paper describes the finite element model by using the program ABAQUS version 6.11  to simulate the cold-formed lean duplex stainless steel -ended columnpin tests conducted by Huang and Young The . measured geometry, material properties , residual stresses, initial local and overall geometric imperfections of the test
