Features: submerged arc surfacing welding core wire, weld-type welding correction, with WF606, excellent welding process performance, beautiful molding, easy to remove slag, welding pile metal is chromium, tungsten low alloy, with precipitation strengthening effect, precipitation carbide at high temperature, can maintain a good high temperature strength. So it has good tempering stability and wear resistance. Before welding, the roller should be preheated to above 450 degrees and held at 450 degrees for 10 hours. Application: for surfacing of support roller, intermediate roller, work roller and extrusion roller.

Kn451-4 Submerged arc surfacing flux cored wire

Product Description:

Hardness of grade stacked metal Chemical composition of hardfacing metal (%)

Thymd451-4 Submerged arc surfacing flux cored wire welding state and after welding at 550℃ tempering, the pile metal hardness HRC≥45 C:0.18 -- 0.35 Mn:1.2 -- 2.0 Cr:4.0 -- 9.0 W:1.0 -- 2.0 Mo:0.6 -- 1.6 other 1.0 -- 2.5

Description: The welding wire with HJ107 flux can be used for surfacing of transition layer of cold rolling support roll. The welding wire has strong crack resistance and no cold crack or hot crack occurs during surfacing. The stacked metal has excellent wear resistance, strong fatigue resistance, and does not fall off when working. Welding arc stability, easy to remove slag, weld forming beautiful.

Application: it is suitable for the repair of 9CrMo,9Cr3Mo,45Cr4NiMoV series cold rolling support roll and the manufacture of composite roll. It can also be used for surface surfacing of important parts which require high strength and wear resistance.
