Rod alloy steel Sanmac 2205

for the plastics industrycorrosion resistanthigh-strength

Sanmac 2205 is a machinability-improved version of the duplex (austenitic-ferritic) stainless steel Alloy 2205. The good machining properties make Sanmac 2205 a superior alternative to standard 2205 grades and other duplex grades for applications subjected to all types of machining by extended tool life and possibilities to increase productivity. Due to its excellent corrosion properties, Sanmac 2205 is a highly suitable material for service in environments containing chlorides and hydrogen sulfide. The material is suitable for use in the extraction of oil and gas from sour wells, in refineries and in process solutions contaminated with chlorides. Sanmac 2205 is particularly suitable for heat exchangers where chloride-bearing water or brackish water is used as a cooling medium. The steel is also suitable for use in dilute sulfuric acid solutions and for the handling of organic acids, e.g. acetic acid and mixtures. The high strength of Sanmac 2205 makes the material an attractive alternative to the austenitic steels in structures subjected to heavy loads.
