Weldability of Ferritic Stainless Steel
Abstract: The ferritic stainless steels are generally considered less weldable than austenitic stainless steels. In case of welding of first-generation ferritic stainless steels, rapid grain growth of ferrite takes place in both the fusion zone and heat-affected zone. These coarse grains have very low ductility and toughness. Excessive grain growth can be avoided by using lower welding heat input and or certain types of additives. They are lower in cost and …
