| dcterms.abstract | Duplex steels are characterized by a dual structure consisting of ferrite and austenite which relationship should be close to 1. They have a combination of good tensile properties, toughness and corrosion resistance, depending on the relationship between the phases mentioned above and chemical composition. They are widely used in chemical process industries and mainly in oil and gas. The development of duplex stainless steels has followed two paths: improved properties by increasing alloying elements such as chromium, molybdenum and nitrogen (super duplex and hyper-duplex) or decreasing molybdenum and nickel, balancing the chemical composition by the addition of N, leading to the development of lean duplex steels. In particular, the last steels were developed to compete with the austenitic stainless steel in many applications where high strength and enhanced resistance to localized corrosion are required. Corrosion resistance cladding is used in the manufacturing and repair industries to increase component durability and low costs. The surface properties of the coating depend on the chemical composition and the microstructure in the area, which in turn are defined by the dilution and the welding process. The objective of this work was to study the effect of heat input (high and low) and the number of layers (one and two) of the cladding with lean duplex steels and duplex stainless steels on the chemical composition, macrostructure, dilution, microstructure and hardness. The welding process used was designed so as to obtain 4 coupons for each consumable (duplex and lean duplex) with 1 and 2 layers welded with high and low heat input (modifying only the welding speed). The increased heat input, generated an increase in penetration, the width and height of the beads, lower dilution and higher ferrite content. Microstructural balance is primarily controlled by the degree of dilution and to a lesser extent, the heat input. | en |
