LIME RUTILE HARDFACING ELECTRODE DEPOSITING WELD METAL WITH COMPLEX CARBIDE PROVIDING HIGH HOT HARDNESS WITH EXCELLENT RESISTANCE TO ABRASION
HV-1000
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 matrix, 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
n 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.
WELDING AMPERAGE AC and DC
OTHER DATA
Electrodes that have become damp should be re-dried at 150ºC for 1 hour.
