1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 11 FC-63 SELF GAS SHIELDING FLUX AND METAL FILLED CORED WIRE FOR HARD FACING APPLICATIONS INVOLVING ABRASION AND IMPACT DATA SHEET NO. 163 SPECIFICATION DIN 8555 CLASSIFICATION MF10-60-GC PRODUCT DESCRIPTION A self-shielded flux cored wire which deposits chromium carbides in the weld matrix to have the hardness in the range 60~63 HRC. The deposit has very high hardness which giving resistance to extreme abrasion, high temperature stability and some corrosion resistance. It is not machinable or heat treatable but can be ground. The minerals dissociate during welding to provide a full protective self-shielding gas which eliminates the need for an external separate shielding gas. WELDING FEATURES OF THE ELECTRODE Suitable for use on DC+ only, the strong forceful arc is readily controlable and the high silicon content of the alloy lowers the surface tension of the molten weld pool, thus allowing ease of weaving and thus minimal dilution. Weld beads are bright and smooth and free from porosity. The slag volume is minimal and metal recovery is about 90% with respect to weight of the consumable. APPLICATIONS AND MATERIALS TO BE WELDED Designed for overlay earth moving equipment, dredge pump parts, gyratory crusher cones and mantles. Other parts that are subject to severe wear. It is also suitable for hard surfacing of mild steel, low alloy steel, and manganese steel. WELD METAL ANALYSIS COMPOSITION % BY Wt.
