With twice the mechanical strength and corrosion resistance of common austenitics, 2205 offers some advantages over 316L and 317L: * Lower coefficient of thermal expansion and a higher thermal conductivity * Resists chloride stress corrosion cracking * Pitting and crevice corrosion resistance * Excellent choice for high chloride environments * Lower cost than high alloyed austenitics Applications Industries taking advantage of the lower cost and higher mechanical properties of 2205 include: * Heat exchangers * Marine construction * Oil and gas industry * Chemical processing www.wilsonpipeline.com
