Sandvik 3R60 has a low carbon content and therefore better resistance to intergranular corrosion than steels of type AISI 316. Conditions when plants are shut down must also be considered, as the condensates which are then formed can develop conditions that lead to both stress corrosion cracking and pitting. Such service conditions should therefore be avoided. This may occur at temperatures above about 60☌ (140☏) if the steel is subjected to tensile stresses and at the same time comes into contact with certain solutions, particularly those containing chlorides. sulphates, sulphides and sulphitesĪustenitic steels are susceptible to stress corrosion cracking. The steel can also be used in sulphuric acid of concentrations above 90% at low temperature. phosphoric and sulphuric acids, at moderate concentrations and temperatures. Organic acids at high concentrations and moderate temperatures.Tests have demonstrated that the steel fulfils the requirements according to the European standards prEN 13445-2 (UFPV-2) ( (min. Hollow bar is stocked in a large number of sizes as SANMAC 316L.įor tube and pipe with wall thickness greater than 10 mm (0.4 in.) the proof strength may fall short of the stated values by about 10 MPa (1.4 ksi).ĭue to its austenitic microstructure, Sandvik 3R60 has very good impact strength both at room temperature and at cryogenic temperatures. Heat exchanger and instrumentation tubes are also stocked in BWG-and SWG-sizes. Sandvik Seamless tube is stocked in a wide range of sizes according to ISO. Sandvik Seamless tube and pipe in 3R60 is supplied in dimensions up to 260 mm outside diameter in the solution annealed and white-pickled condition or solution annealed in a bright-annealing process.
