MK·G60
Published：2009/12/17
Standard:GB ER55-D2-Ti AWS ER80S-G JIS YGW21
Characteristics:MK G60 is low alloy steel gas shielded welding wire, strengthened by Mn、Mo、Ti, with the use of CO2 or the Ar+20%CO2 gas shielded, it has good weldability, higher melting deposited metal strength, and at same time it also has excellent low temperature toughness.
Application:The welding of structures of low carbon steel of 600-700MPa and low alloy medium -high strength steel, e.g. Q460, Q550 etc.
