DYD61X series high chromium cast iron surfacing flux cored welding wire is one of characteristic products in our company. With extremely high abrasion resistance, it is widely used in manufacturing and repairing of wear material of the industries of mine, electric power, metallurgy, architecture and so on. The longer service life of abrasion pieces is improved by the correct selection of surfacing flux cored welding wire. DYD61X series are significant for the broad economic efficiency and huge social value.
Welding wire
Type Hardness
HRC Chemical composition of Surfacing Layer (weight %) Performance and typical application
C Cr Si Mn other Fe
DYD611 55 4.5 25 1.0 1.3 the rest The surfacing layer that contained thousands of carbides is optimal abrasion-resistant and high temperature with 400 Centigrade from 500 Centigrade .The advantage of the surfacing layer :the stress is releasing and welding cracks is in close texture.
It is applicable in manufacturing and repair ing of wear material such as Pulverizer Roll Wheel, the liner of thermal power plant and vertical grinding roll,Liner Plate,blade of Auger Drill of cement factory.
