Alloy 2205 (UNS S31803) is one of the most recognized and widely used duplex stainless steel grade, with excellent general corrosion resistance and superiority over grade 304 or 316 in most environments. Ranflex Metals is a stockholder and supplier of various grades of duplex stainless steels including UNS 31803 (F51) and UNS 32205 (F60) Alloy 2205. The ratio of ferrite to austenite in Duplex stainless steel is approximately 50:50.
The characteristic feature of duplex stainless steels is their dual phase microstructure, comprising of approximately 50% of austenitic and 50% of ferrite. The yield strength of duplex stainless steel is typically double that of austenitic stainless steel.
Duplex fittings, duplex pipes and duplex plates are one of the key product items of Ranflex Metals and are widely supplied from stock to various industries such as chemical, petrochemical, marine, oil and gas and transportation. Duplex pipes, tubing’s and fittings are widely used for oil field piping works and heat exchangers, duplex plates are used in manufacturing vessels, while duplex bars are used for manufacturing fasteners and high strength pump shafts.
Duplex stainless steel plates are considered as a cost effective grade due to lower nickel and molybdenum contents than their austenitic counterparts of similar corrosion resistance. Due to the lower alloying content, duplex stainless steels plates are generally lower in cost. Also, due to higher yield strength it could also be possible to reduce the thickness of duplex stainless steel products, compared to austenitic stainless steel. The dual benefit of lower prices and weight savings make duplex stainless steels plates economically very effective for project managers.
The ASTM A240 specification covers chromium, chromium-nickel, and chromium-manganese-nickel stainless steel plate, sheet, and strip for pressure vessels and for general applications. The steel shall conform to the requirements as to chemical composition specified. The material shall conform to the mechanical properties specified.
