镍基药芯焊丝625-AP AWS A5.34 ENiCrMo3T1-1/4

CLASSIFICATIONS:

ENiCrMo3T1-1/4 per AWS A5.34

APPLICATIONS:

SelectAlloy 625-AP is an all position, gasshielded,flux cored electrode primarily used for welding alloys 625, 601, 802
and 9% nickel to themselves and to steel.It is also widely used for surfacing steel and for joining other nickel-based alloys
to steel.

SelectAlloy 625-AP, with its nickel-chromium-molybdenum weld deposit, makes it a smart choice for surfacing,producing a corrosion resistant deposit for harsh environments. This electrode is utilized to clad steel when exceptional corrosion resistant is required such as chloride-contaminated cooling water in heat exchangers as well as offshore and marine environments.

SelectAlloy 625-AP is extensively used to join the 9% nickel steels utilized in LNG storage and conveyance equipment and join steel to nickel-base alloys.
