NORAM SX™ is the trademark for the austenitic stainless steel, UNS S32615, which was developed by Sandvik in Sweden specifically for use in hot concentrated Sulphuric Acid. SX alloy is considered to be the benchmark in sulphuric acid service, with over 35 years of unparalleled performance offering numerous advantages over other materials of construction.
The corrosion rates for NORAM SX™ are practically nil in the typical operating range of the acid plant circuits. Corrosion properties are equally good for the base material and the welds, also under dynamic conditions.
NORAM SX™ is readily workable and matching welding consumables are available for GTAW, GMAW and SMAW processes.
NORAM SX™ is available from stock in a large variety of forms, such as plate, tube, pipes, fittings, wire, bar and welding consumables.
