Effect of Post-Weld Annealing on Microstructure and Growth
WebHeavy welded sections in Grade 316 require post-weld annealing for maximum corrosion resistance, this is not required for grade 316L. Heat Treatment. Annealing temperature … WebNormally, once the whole of the workpiece is at the annealing temperature, the annealing time should be between 10 and 30 minutes, depending upon the section thickness. The shorter times within this range should be used for thin sheet components. The longer times should be used for thick (heavier) sections. Websections may require post-weld annealing. This step is not required for 304L. Grade 321 may be used if post-weld heat treatment is not possible. Supplied Forms 304 is typically supplied by Aalco in a range of finishes in the following forms: Sheet Plate Welded mesh Quarto plate Round bar Flat bar and rolled edge flat bar Equal angle newberg or city map
