 DIN 8559 :  SG Mo
 EN 440 :  G 2 Mo
 Description and Applications
 Arctech SGMo is a copper coated Mo bearing mild steel solid wire electrode
 suited for pressure vessels, high tensile pipe, earth moving machines,
 crane construction and as well as in structural engineering.
 It provides high quality, very tough and high strength (both as welded
 and stress relieved) deposit which is recommended for the temperature
 range from -40ºC-to 550ºC.
 It provides excellent weldability with powerful desoxidizers for Ar/CO2
 mixtures. Preheat and inter pass temperature and post weld heat
 treatment are dictated by the base metal.
