R407G Heat Resistant Steel Flux Cored Wire

  • Description
Product Detail

    Application

    Applying for welding Cr2.5Mo pearlitic heat-resistant steel(eg:2.25CrMo).Eg:High temperature and high pressure pipeline, synthetic Chemical equipment, Petroleum cracking equipment, repairing for alloy steel casting.

    Characteristic

    It is alkalinity slag-systems mixed (calcium oxide+ fluoride) gas shield flux cored wire for pearlitic heat-resistant steel. Besides the excellent plasticity and good mechanical properties and good mechanical properties and  anti-cracking ability,it also has the advantage of arc stability, fine welding appearance , especially norma- temperature and low-temperature impact toughness. Suitable for full position welding, and the preheating and interpass temperatures are 200-300?.
