Description: Low-sodium type coeting of low alloy heat-resistant steel electrode, suitable for DC reverse polarity, short are operation, all-position welding can be carried out. Transition from core alloy composition operating characteristics of an electrode, and welded joints of high strength, excellent creep resistance at elevated temperatures can get good strength and toughness. Suitable for field installation and construction, compliance with AWs A5.5 E8016-B6 sbout the project requirements. And compared to ordinary steel welding material and deposited wetal purity.
Application: Used in petroleum refining petrochemical, chemical, power generaticn and other conditions of use harsh, corrosive medium large, complex equipment aSME SA387. Gr. 5 (5Cr-0.5Mo) welding of steel.
