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.
