SA203GrE offers excellent low-temperature impact toughness and mechanical properties. It is typically used in low-temperature environments ranging from -70°C to -101°C (in quenched and tempered condition, up to -107°C). It is widely applied in low-temperature separation, air separation, liquefied gas storage, and other fields. In recent years, this material has been used in domestic coal chemical projects for equipment such as CO₂ absorption towers, H₂S absorption towers, H₂S concentration towers, and methanol scrubbers. The maximum thickness used is 110 mm.
