Product Description
High-quality stainless steel plate
ZHEJIANG ZHONGZHENG STAINLESS STEE MANUFACTURING CO., LTD
is a special stainless steel manufacturer with 20 years of manufacturing experience.
2205 (UNS S32305/S31803) is a 22% chromium, 3% molybdenum, 5-6% nickel, nitrogen alloyed duplex stainless steel plate with high general, localized, and stress corrosion resistance properties in addition to high strength and excellent impact toughness.
2205 duplex stainless steel plate provides pitting and crevice corrosion resistance superior to 316L or 317L austenitic stainless steels in almost all corrosive media. It also has high corrosion and erosion fatigue properties as well as lower thermal expansion and higher thermal conductivity than austenitic.2205 duplex stainless steel plate is particularly suitable for applications covering the -50°F/+600°F temperature range. Temperatures outside this range may be considered but need some restrictions, particularly for welded structures.
Duplex Stainless 2205 Applications
? Oil and gas exploration and processing equipment - piping, tubing, and heat exchangers
? Marine and other high chloride environments
? Effluent scrubbing systems
? Pulp and paper industry - digesters, bleaching equipment, and stock-handling systems
? Cargo tanks for ships and trucks
? Food processing equipment
? Biofuels plants
