UNS S32615 is a high silicon containing austenitic stainless steel. It was developed by Sandvik exclusively for use in concentrated sulphuric acid. Haohua AB is a wholly owned subsidiary of Sandvik and introduced SX to the industry in 1985. Haohua continue to market SX world wide through its licensees, agents and representatives.
Haohua has developed a complete standard for pipes, flanges and fittings made of SX. The standard is based on ASME B 31.3 and covers the size range from DN 25 (1”) up to DN 600 (24”). Flanges are available in ISO, PN 10 and ANSI B16.5 (150 lb) standards. Larger dimensions and other custom parts are manufactured according to individual customer needs.
