Alloy ER 320LR has a composition similar to Alloy ER320, except that carbon, silicon, phosphorus and sulfur levels are kept at lower levels as well as the columbium and manganese being specified at a narrower range. The low melting residuals are limited in this alloy to reduce the possibility of micro fissuring. It is for this reason that the alloy ER320 LR is often used for welding Type 320 stainless steels.
