CarTech 316L-SCQ stainless is an austenitic stainless designed for use where extremely good surface finishes are required. The corrosion resistance and mechanical properties of CarTech 316L-SCQ stainless are similar to CarTech 316L. Typical specifications for bar products are ASTM A-276 and SEMI F20.

CarTech 316L-SCQ stainless is produced to a tightly controlled chemical com-position within conventional analysis limits CarTech 316L. Carefully selected melt stock is utilized to restrict the occurrence of typical residual elements. One important element, sulfur (S), influences inclusion count, machinability and weldability, and can be varied according to customer specification. The intermediate sulfur range is controlled to 0.005 to 0.015% for a unique combination of weldability and micro-cleanness. For the ultra-pure composition, sulfur is held in the range of 0.001 to 0.004% maximum. Either of the compositions may be melted by air melting + Vacuum Arc Remelting (AOD+VAR) or by Vacuum Induction Melting + Vacuum Arc Remelting (VIM+VAR) depending on the level of micro-cleanness required.

Applications:
CarTech 316L-SCQ stainless could be considered for use in applications where cleanness, resulting in reduced inclusions, is advantageous in thin-wall components such as valves and fittings.

Industries in which this alloy could be considered for applications include semiconductor, nuclear, biopharmaceutical, aerospace, and chemical and gas processing.
