Compared with 13Cr, the mechanical properties and corrosion resistance of super13cr are improved. The decrease of carbon content improves the weldability and keeps the microstructure of martensite.
UNS 41426 super 13Cr has rod material and pipe material, which is mainly used for OCTG pipeline, shell and downhole equipment for well completion.
