A premium metal-cored, gas-shielded chromium carbide hardfacing alloy that has a high volume fraction of carbides dispersed in a hard matrix. Excellent out-of-position weldability. For applications involving high abrasion and mild or moderate impact. Deposit polish in service and are hear resistant to 1000ºF(531ºC). Use on carbon and low alloy steels. When used with 100% CO2 or 75/25 Argon/CO2, it offers excellent weldability in flat, horizontal and vertical down positions, the arc is very stable at both high and low voltages settings, and the smoke level is very low.

POSTALLOY PS-10 is a tungsten carbide, nickel base hardfacing wire designed to resist severe abrasion but unlike traditional tungsten carbide wires, it absorbs more impact without fracturing. Because of the unique chemistry, Tungsten-Carbide-Nickel-Chromium-Silicon-Boron, it also has excellent resistance to erosive wear, frictional wear, corrosive wear, and maintains its hardness, even at temperatures of 1100ºF (565ºC). Weld deposits contain over 50% fully fused, pre-alloyed carbides. The alloying elements in this wire produce a high hardness alloy that encapsulates and protects the carbide particles, reducing premature wear caused by erosion next to the carbide particles. Postalloy PS-10 has very good weldability and a very soft arc, this, in combination with the nickel matrix, reduces weld dilution and carbide dilution to produce a truly outstanding multi-wear wire.

POSTALLOY® PS 133 is a large diameter, metal cored, self shielding, hardfacing wire for use in a wide range of applications where abrasion is severe, including overlay plate production, the rebuilding of coal & cement clinker pulverizer rolls and tables, mining and agricultural ground engaging equipment such as bucket teeth, rippers, subsoilers and injector knives. Deposits are ultra high in carbon and chromium, ensuring maximum carbide population and wear protection, even on the first layer. The large diameters are ideal for automated applications where maximum deposit rates are required.

A martensitic tool steel type alloy with numerous tightly packed carbides for excellent abrasion resistance under high impact. Deposits are smooth and free of any slag. One layer deposits exhibit wear characteristics that you would expect from chromium carbide hardfacing products. An excellent choice for applications requiring crack free deposits with good wear characteristics. Also an excellent wire for MIG Carbide

Postalloy PS-98 is a metal cored, triple deoxidized Iron based wire, alloyed with Chromium and Tungsten. This product is primarily used as a matrix alloy for the Tungsten Carbide embedding process. Unlike soft mild steel welding wires, which are commonly used in the embedding process, the microstructure of PS-98 is designed to encapsulate and protect the Tungsten Carbide particles from premature erosion. Many of the common embedding wires are solid which require high voltage and amperage setting to achieve a fluid puddle. Postalloy PS-98 is metal cored and develops a spray transfer at very low current levels. This combined with it’s unique alloy content forms a very fluid weld puddle. This promotes an even dispersion of Tungsten Carbide particles within the weld puddle. These unique properties make it an ideal choice when used with the Tungsten Carbide embedding proccess.

Postalloy Super-Edge is an abrasion resistant, gas shielded, high speed tool steel wire designed for applications where edge retention is a primary concern. Weld deposits are martensitic with micro-carbides evenly dispersed throughout the deposit. These properties create a fracture resistant cutting edge even under high compressive loads. Postalloy Super-Edge is alloyed with molybdenum and tungsten for superior high temperature hot hardness. This property helps maintain a sharp edge under localized high heat conditions created by extreme friction. Super-Edge has very good build-up characteristics which is especially helpful when welding along edges.

A general purpose self-hardening overlay with a good combination of resistance to abrasion and impact Postalloy 2898-SPL is very tough with excellent resistance to chipping and spalling. Deposits will retain their hardness and maintain a good cutting edge up to 1100OF(595OC) .
