MK·H08Mn2SiA
Published：2009/12/17
Standard:GB ER49-1 AWS ER70S-7 JIS YGW12
Characteristics:MK H08Mn2SiA is copper coated gas shielded welding wire of carbon steel and low alloy steel, deoxidized by Mn and Si in welding wire, it is able to prevent the forming of pores and slag in the weld (weld bead), increase the cracking resistance, and get good mechanical properties of the weld.
Application:For single or multiple weld welding of carbon steel and 500MPa grade low alloy steel. (e.g. the welding of vehicle, bridge, construction, and mechanical structure etc)
