Metal Cored Wire
MAXFIL-MC-31
AWS: SFA 5.18 E70C-6M H4
EN ISO CODE: 17632-BT493T15-0MA-K
Maxfil-MC-31 is a gas shielded metal-cored wire (MCAW) designed for welding of low & medium tensile steel structures subjected to dynamic loading. The wire encompasses the deposition advantages of flux cored wire along with the high deposition efficiencies of a solid wire with both single and multi-layer applications. The deposited weld metal by MCAW is virtually free from slag covering and thus reduces post- weld cleaning time. The wire burns with a smooth arc and low spatter. Weld metal contains extremely low diffusible hydrogen (<4ml per 100gm). Maxfil-MC-31 is suitable for welding of similar composition steels and equivalent grade steels like; D/E/F/G grades of SA-414, Gr.60/Gr.65 steels of SA-515, Gr.60/ Gr.65 steels of SA-516, etc. This MCAW wire can be used for robotic welding applications.
