ER320LR is basically a modified version of ER320, where the “residuals’’ — carbon, silicon, phosphorus and sulfur are specified at lower maximum levels. The columbium and manganese content of ER320LR is also maintained within a tighter range. These strict controls eliminate hot cracking and microfissuring frequently encountered in austenitic stainless steel.
