UTP 3127 LC description: Like the base material 1.4563 this alloy distinguishes itself by high resistance against phosphoric acid and organic acids. Due to the addition of Cu besides Mo it shows extremely low corrosion rates, particularly when used in sulphuric acid. Due to the high Mo-content of more than 3,0 % in combination with approx. 27 % Cr, the stick electrode UTP 3127 LC distinguishes itself by resistance against stress corrosion crakking, crevice corrosion and pitting in media containing chloride ions.
