1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 11 FC-34 SELF GAS SHIELDING FLUX AND METAL FILLED CORED WIRE FOR HARD FACING APPLICATIONS INVOLVING ABRASION AND IMPACT DATA SHEET NO. 160 SPECIFICATION DIN 8555 CLASSIFICATION MF1-350-G PRODUCT DESCRIPTION A self-shielded flux cored wire for heavy build-up and as a basis for harder finishing layer. The deposit contains small percentages of carbon, chromium, silicon, and manganese, which results a crack-free wear resistance deposit with a hardness about 34 HRC, dependent upon parent material dilutions and number of layer. It is particularly suitable for conditions of moderate abrasion and friction, coupled with resistance to heavy impact. WELDING FEATURES OF THE ELECTRODE Suitable for use on DC+ only, the strong forcefull arc is readily controllable 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 repairing or rebuilding of ferritic and austenitic steel. Typical applications include railroad frogs, crusher rollers and hammers, dipper gums, track pads. Also for buffer layers before hard surfacing with chromium carbide alloys.
