Sanicro® 35 Bridges the Gap Between Stainless Steels and Nickel Alloys for Chemical and Refinery Industries
Our high alloyed austenitic stainless steel Sanicro® 35 is used globally by several chemical and refinery industries as it’s an excellent high-performance solution for highly corrosive environments.
Bridging the Gap
Sanicro® 35 can be used instead of conventional high nickel alloys and super austenitic alloys to support more cost-effective and efficient operations for industries including chemicals, refining, bio-refineries, biomass, waste gasification, and chemical recycling.

Corrosion Resistance and Versatility
Sanicro® 35 has extremely good pitting and crevice corrosion making it suitable where seawater is used for cooling or heating. It has a high resistance to general corrosion in acid environments. It can be used in heat exchanger applications such as overhead condensers and seawater coolers, hydraulic and instrumentation tubing, chlorinated hydrocarbon applications, and Purified Terephthalic Acid (PTA) environments. In the chemicals industry, it can be used with organic acids (such as formic and acetic acid) and inorganic acids (such as phosphoric acid and sulfuric acid) and is available in round bar, seamless pipe, and plates or sheets.
