Duplex Stainless Steel Mechanical properties Duplex steels are characterized by high strength. High strength also means that fatigue properties are very good. However, fatigue strength is dependent on:The components design shape. The welded joint itself. The welding method and joint type are also of great significance. Example: Influence of Welding Speeds on the Morphology, Mechanical The results show that the welding speed has a significant effect on the weld morphology, the two-phase ratio, grain boundary misorientation angle (GBMA), and mechanical properties of the welded joint. When the welding speed increased from 280 mm/min to 340 mm/min, the austenite content and the two-phase ratio in the weld metal zone (WMZ) decreased.
Jan 01, 2020 · The mechanical properties of PX-Al/ST16 steel joints (samples S1 to S5) and ST-Al/ST16 steel joints (samples S6 to S9) are shown in Fig. 12. For the PX-Al/ST16 steel samples S1 to S5, the tensile/shear strength was around 2400 N and the cross-tension strength varied, when the sleeve plunging depth increased from 0.9 mm to 1.0 mm, and the Laser-CMT Hybrid Welding-Brazing of Al/Steel Butt Joint 6A01-T5 aluminum alloy and SUS301L-DLT austenitic stainless steel sheets were welded by a laser-cold metal transfer (CMT) hybrid welding-brazing method with ER5183 filler wire. We researched the weld forming, intermetallic compounds, and mechanical character, which are influenced by laser power, wire feeding speed, and welding speed.
Aug 14, 2020 · This study focuses on the microstructure and mechanical properties of the joints of Q235 mild steel, which was formed by the friction stir welding (FSW). The results indicated that, after the FSW, the heat-affected zone (HAZ) of the retreating side (HAZRS) and the HAZ of the advancing side (HAZAS) recovered under the influence of the heating cycle. Microstructure and mechanical properties of fiber laser Jun 01, 2018 · A 1.36 mm thick QP980 steel sheet manufactured by Baoshan Iron & Steel Co., Ltd. was used in the present study. The chemical compositions and tensile properties are listed in Table1.The microstructure of QP980 base metal (BM) consists of martensite, ferrite and a small amount of retained austenite, as shown in Fig. 1.The presence of retained austenite was verified by x-ray diffraction (XRD
