An online webinar was held on 25 February, which discussed engineering principles to allow understanding of the welding metallurgy of duplex and super duplex stainless steels.
The primary alloying additions are chromium and nickel. The weld solidification of duplex stainless steel is entirely ferritic,. Ferritic stainless steels are non- hardenable Fe- Cr alloys. 2 Metallurgy of steel When carbon in small quantities is added to iron, ‘ Steel’ is obtained. Welding Metallurgy Phases, Invariant Reactions, Equilibrium Phase Diagrams and. Heat treatment of carbon and low- alloy steels is discussed and related to the effect of welding thermal cycles on resulting structure and properties of steels in the heat- affected- zone and weld metal. Title: Welding Metallurgy of Duplex Stainless Steels Date: May 27,. As with the other types of stainless steels, the austenitic stainless steels are corrosion and oxidation resistant due to the presence of chromium that forms a self.
When considering the operational performance of stainless steel weldments the most important points to consider are corrosion resistance. Views 46MB Size Report. , the distance from the fusion line), which determines the austenite. Weldability issues are divided into. Welding metallurgy and weldability of stainless steels / John C. 1% C Up to 2% Mo Martensite possible, but < 20% Average weldabilty, better than Martensites, worse than Austenites Carbide precipitations ( C- diffusion ins fcc- iron) Coarse grain formation.
THE WELDING OF STAINLESS STEELS 2 1 General Information on Stainless Steels 1. Welding of High- alloyed Steels - Weldability and Problems Ferritic Stainless Steels 13% to 30% Cr, < 0. Designer Handbook The purpose of this booklet is to help designers and manufacturing engineers achieve a better understanding of the welding characteristics of stainless steels, so they may exercise better control over the finished products with respect to welding. Types 405, 409, 430, 4 are representative of this group. General Physical Metallurgy Concepts common to all alloy systems 2. These stainless steels also have a lower coefficient of thermal conductivity, which causes a tendency for heat to concentrate in a small zone adjacent to the weld.
