What is stainless steel filler?

Stainles s steel filler metal are frequent­ ly use d to wel austenitic an ferritic steels. Typically, the austenitic stainless stee ha s a CTE that i 30 % to 40 greater than that of a ferritic steel. This CTE mismatch is frequently responsible for problems that occur in these type of joints.See all results for this questionWhat is austenitic stainless steel?Austenitic stainless steels are clad on ferritic steels to provide corrosion resistance. Typically these welds cover large surface areas relative to other weld­ ing processes, and an understanding of how the CTE varies with dilution would be helpful in selecting proper filler met­ als.See all results for this questionThermal-Metallurgical-Mechanical Analysis of Weldment thermal metallurgical analysis of gma welded ah36 steelThermal-Metallurgical-Mechanical Analysis of Weldment Based on the CFD Simulation.
