Accurate Metals and Alloys has been highly regarded as a steadily excelling firm known for distributing and formulating the duplex steel products such as the duplex steel 2205 plates of superior most quality. The richness of quality characteristic of our products is accompanied by its cost-effective nature. The raw materials we employ for manufacturing are procured from trusted sources and tested before they are assembled through modern technological equipment.
The ‘duplex’ in the duplex steel 2205 plates stand for the two types of microstructures composing the overall structure of the plates, the two classes being ferritic and austenitic. The physical combination drastically increases the yield strength and toughness of the alloy. Another distinct alteration is in the chemical composition of the plates, where the amount of chromium exceeds that of any other normal stainless steel grades at 22-23%. The enhancement in chromium is accompanied by the increment in other elements as well, such as 3-3.5% molybdenum and 4.5-6.5% nickel in the composition. The increment in the vital elements grants the plate improved properties, both mechanical and chemical.

Duplex steel plates of grade 2205 are deemed to be an improved form of stainless steel with enhancement in properties such as strength. The toughness and the yield strength of the plates are said to be almost double that of normal austenitic grades. The corrosion resistance displayed by the duplex steel of the grade in consideration is exceptional with the plates being resistant not only against mild acids but also against strongly acid and oxidizing conditions. Pitted and crevice corrosion both are tackled by the plates effectively. Elevated temperatures and harsh conditions are known to cause stress corrosion in many austenitic stainless plates of steel, but with duplex steel, soaring temperatures don’t pose any form of problems on the plates and they, therefore, excellently resist stress corrosion. All the chemical and physical properties of the plates when coupled with the durability and stability they exhibit make it an ideal choice for usage.
The uses of duplex steel 2205 plates are employed in various industries and equipment such as seawater applications, scrubbers, pulp and paper industry, biofuel plants, chemical processing industry, cargo tanks, oil processing, etc.
Tests are periodically conducted on the products we fabricate and inspections are also held to evaluate the factory conditions so that the quality and the integrity of the products we dispatch haven’t deteriorated in any form.
