E320LR-16
Alloy Type: A5.4, STAINLESS STEEL Covered Arc Welding Electrodes
E320LR-16 is similar in composition to 320 stainless steel but with carbon, silicon, phosphorus, and sulfur controlled to lower limits and columbium and manganese kept to a narrower range. The resulting composition is designed to reduce the possibility of microfissuring. Low heat input is advised when welding with E320LR-16 electrodes.
Typical Applications: tanks, process piping, heat exchangers for the chemical processing industry
