100-W-IM HARDFACING Welding WIRE
100-W-IM
100-W-IM hardfacing welding wire is a tubular wire for gas shielded metal arc hardfacing. Provides martensitic weld metal with good abrasion and impact resistance.
This wire is especially useful in applications of 2-3 layers for maximum wear resistance. The 100-W-IM should be used when good resistance to abrasion and impact is required. The 100-W-IM will not cross crack.
