1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 9 HR-6600 LIME RUTILE HARDFACING ELECTRODE DEPOSITING WELD METAL HIGH IN CHROME CARBIDE PROVIDING EXCELLENT RESISTANCE TO ABRASION DATA SHEET NO. 124 SPECIFICATION CLASSIFICATION DIN 8555 E10-UM-65-G PRODUCT DESCRIPTION The design emphasis of the flux is designed to ensure a slag solidification range that allows the chrome carbide particles to be evenly distributed within the austenitic alloy matric, so ensuring complete uniformity of hardness. The balanced lime rutile flux contains the appropriate alloying elements and is bound with a blend of silicates that ensures both coating strength and resistance to moisture absorption. WELDING FEATURES OF THE ELECTRODE The electrode welds with a smooth stable arc and easily strikes and re-strikes. Weld appearance is bright, almost of polished appearance, smoothly contoured and slag detachability is excellent. The metal recovery is some 170% with respect to core wire weights, thus reducing welding time. The weld deposits are non-machinable. APPLICATIONS AND MATERIALS TO BE WELDED Suitable for surfacing a wide range of steels including 13Mn types. Because thermal contractional stresses will cause stress relieving cross-cracking, build- ups should be limited to 3 layers, preferably two when restraint is high. The deposit has excellent resistance to abrasion against minerals, sand and sludges which leads to its extensive use in the earth moving, cement, dredging and steel industries. For build-ups on carbon and low alloy steels or 13Mn steel NSB-307,should be used as a buffer layer. WELD METAL ANALYSIS COMPOSITION % BY Wt.
