UNS S32615 Sheet
UNS S32615 Sheet is a high-silicon austenitic stainless steel product, which is available in thin-gauge to provide an excellent corrosion resistance level to be used in lining, cladding, and fabrication of material in hostile chemical conditions. UNS S32615 sheet, which is made to ASTM A240 / ASME SA-240, has the same alloy chemistry as plate 4.860% silicon and 1.52.5% copper, and is available in a variety of thicknesses and surface finishes. It finds application in tank lining, troughing, ducting and fabricated parts in acid processing, metal finishing, and pulp and paper industries in which thin-section corrosion protection is of critical importance.
