Alloy31 Material introduction

Alloy31 (NS1404, UNS NO8031, Good plasticity, good cold and hot forming and welding properties make this alloy an iron nickel base corrosion resistant alloy with the best comprehensive performance. It has been used in chemical processing such as phosphoric acid and sulfuric acid and in marine development, pulp, paper making, and flue gas desulfurization devices of coal-fired (oil) power plants.
