00H19N40B (EP337U)

It is an alloy used for the manufacture of rolled products, which can later be used as parts in the chemical, petrochemical and power engineering industries. Parts made of 00H19N40B alloy have good resistance to chloride-containing water vapor at temperatures up to +350 ° C, as well as to the atmosphere with hydrogen sulfide content. Also, this alloy is not subject to the process of corrosion, in particular a point one.
