 Use 
 For axles, gears, welding mixer blades and other components. General valve sealing surface for welding. For thermal processing tool and die welding, such as hot roll, hot shear blades, hot forging and so on. Used by the abrasive wear and adhesive wear of the parts surface, such as bucket and other gear. Worn parts by welding a variety of surfaces. Welding wire of high hardness, can be used for the crankshaft, Roberts tank and other components of the surfacing. The following welding work station 570 ℃ high-pressure valve sealing surface of the boiler equipment and other type of welding high chromium cast iron parts for high temperature wear and corrosion resistance the surface of the welding parts, such as rubber machinery, hot roll. Equivalent Arnco100XT, 200XT flux cored wire, special surfacing in the oil drill pipe joints.

 Note: Hardness is surfacing in the 16Mn board of more than 4 layers hardness, chemical composition of the sampling location should be more than 10 mm from the base metal. 
 Does not affect the hardness and other properties in the case of chemical composition of deposited metal can have a small change. 
 Depending on the circumstances, the workpiece to the different levels of pre-and post-treatment.
