Abstract

The corner of a welded sheet construction made from austenitic corrosion-resistant chromium-nickel steel showed corrosive attack of the outer sheet. This attack was most severe at the points subjected to the greatest heat during welding. Particularly large amounts of weld metal had been applied. Microscopic examination showed grain disintegration was promoted by the thickness of the weld bead and the amount of heat required to produce it. If nonstabilized austenitic sheet is to be used in the future, one of the particularly low-carbon steels, X2 CrNi 18 9 or X2 CrNiMo 18 10, is recommended.
