Duplex plate has a two or dual phase micro structure. The microstructure of the Duplex Steel S32205 Foil consists of ferrite and austenitic in an equal proportion. This stainless steel if often recommended by duplex 2205 plate suppliers in Mumbai because it offers a combination of attractive properties such as its high tensile strength along with its excellent corrosion resistance properties. The ASTM A240 Type 2205 Duplex Sheet, when supplied in an annealed condition offers a maximum Brinell hardness value of about 290 .

As noted by many SA-240 Duplex 2205 Plate suppliers, the alloy has been characterised by high yield strength, which tends to be almost two times that of any standard austenitic stainless steel grades. Further the superior properties of the Thick 2205 SS Sheet includes good fatigue strength plus excellent resistance to chlorine related stress corrosion cracking, crevice corrosion, pitting, erosion corrosion as well as general corrosion even in severe environments. Again in terms of these properties, the 2205 Plate Material Stockist tends to normally outperform the standard or conventional austenitic stainless steel grades.

Although the 2205 duplex stainless steel plate cannot be hardened by thermal treatment, but its strength and hardness can substantially be increased by a cold working process, with a subsequent reduction in its ductile properties.Therefore the duplex 2205 plate suppliers recommend using the alloy extensively in the fields - Marine, Pulp and Paper, Oil and Gas, Chemical, Petrochemical, Transport and allied processing industries.
The ASTM A240 is a specification standard which covers several chromium based stainless steel grades which have been manufactured in the form of either plates, sheets, or ASTM A240 Gr 2205 Strip. The ASTM A240 Gr 2205 Strip is meant for applications that involve being used in either for general applications or in pressure vessels. The steel ASTM A240 Type 2205 Coils needs to conform to the requirements of the chemical composition as mentioned in the ASTM A240 specification.
