From a fabrication viewpoint, i.e., with regard to manufacturing of components and equipment, they are to some extent similar to standard austenitic grades such as 1.4301 and 1.4401, but they still require special know-how with regard to welding and machining. Outokumpu Stainless manufactures a numbers of steels of this type: 904L, 254 SMO and 4565. 4529 can also be delivered if specified. The properties of 4529 are in general terms very similar to those of 254 SMO. In certain applications the grades 4439 (austenitic) and 2205 (duplex) may be used as an alternative to 904L, whilst SAF 2507 (duplex) may be used as an alternative to 254 SMO. More information concerning duplex options is available in the data sheet for duplex steels. Chemical composition The chemical composition of a steel grade may vary slightly between different national standards. Consequently, a specified standard should always be stated when ordering. General characteristics High performance austenitic stainless steels differ substantially from more conventional grades with regard to resistance to corrosion and, in some cases, also mechanical and physical properties.
