1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 9 HV-1100 LIME RUTILE HARDFACING ELECTRODE DEPOSITING WELD METAL WITH COMPLEX CARBIDE PROVIDING EXCELLENT RESISTANCE TO ABRASION DATA SHEET NO. 123 SPECIFICATION CLASSIFICATION - 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 stable arc and strikes and re-strikes readily. The weld bead is smooth but not as bright as that obtained with straight chrome carbide types and the weld profile is slightly more convex. The metal recovery is some 180% with respect to weight of the core wire, thus reducing welding time. The weld deposits are non-machinable and non heat treatable. APPLICATIONS AND MATERIALS TO BE WELDED In addition to conventional applications, involving heavy abrasion resistance against minerals etc, this alloy is used to particular advantage when the component to be surfaced is subject to use at elevated temperatures, eg: bell housings on blast furnaces, cement furnaces, pump casings and so forth.
