Introduction:HBWH-80 800MPa grade high strength copper wire, protective gas for the rich argon.The wire through the low C, high Mn and trace element of the Ti treatment and proper quantity of Ni, Mo alloy elements such as precipitation strengthening, solid solution strengthening, grain refinement, the weld seam with high strength and high toughness, and stable arc, little splash, can be used for the full range of welding.
Application: Widely used in the welding of hoisting machinery, mining machinery, engineering machinery, vehicles, vessels, and other pressure vessels 800MPa grade high strength steel and low alloy structural steel (such as Q690).

Note:
1. Packing: 15kg/spool/box
2. Welding wires of other specifications can refer to the standards, and proper changes may be required according to actual needs;
3. While welding, the use performance of welding wires and the mechanical property of fused metal will be affected if it is off the standards.
