Super Duplex

Steel grade 1.4410 ( also called UNS S32750 , F53 and 2507) is a superduplex stainless steel characterized by higher contents of chrome, molybdenium and nickel than standard duplex steels, resulting in increased corrosion resistance. These steels were developed for applications in aggressive chloride environments.

super duplex uns s32750 round bars is a super duplex stainless steel with higher alloy content, thus making it superior in corrosion resistance and strength. The processing with the saw in super duplex uns s32750 bars is a mechanical processing of the material, which results in a suggestively lower inadvertent deformation and augmented hardness for the prevailing structure. The application of super duplex f53 are in oil & gas industry machinery, offshore platforms, process & service water systems, heat exchangers, fire-fighting systems, ballast water & injection systems. In dilute sulphuric acid contaminated with chloride ions, super duplex uns s32760 round bars has better corrosion resistance than ss 904l, which is specially designed to resist pure sulphuric acid. The machined work-piece of super duplex uns s32760 bars has a homogeneous structure even at the edge, which does not change in the continuation of the material.
