Flitewear 4

Postalloy® Flitewear 4 is a medium carbon, chromium hardfacing alloy that produces a semi-austenitic matrix with uniformly distributed chromium carbides. Recommended for applications involving moderate abrasion with heavy impact. Weld metal is tougher than conventional chromium carbide alloys with fewer stress relieving check-cracks. Flitewear 4 can be applied to carbon, low alloy, and manganese steels.

Flitewear Hardfacing wires have been engineered to improve the efficiency and longevity of screw conveyors, augers, rendering screws and other similar components. They are designed with in mind, where environmental and production issues are unique. They offer excellent welder appeal and out-of-position welding capability. Bead configurations can vary from stringer to wide weave patterns. Welding arcs are smooth and quiet; smoke levels are extremely low; weld deposits are slag free and spatter-free.

Welding Procedure

While all sizes of Flitewear 4 will operate with or without a gas cover, you may find applications for .045 and 1/16 for which you prefer a shielding gas. If a gas cover is used, Argon/CO2 or 100% CO2 is recommended. This will cause amperages to go up by about 10% and the stick-out should be shortened. When welding out of position, use the lower range of amperages and voltages. In addition, a gas cover may be useful, especially when using a constant current power source and voltage sensing feeder.
