E320LR-16 Stainless Steel Arc Welding Electrode Blue Demon

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.
