Postalloy 2747FCG

Postalloy 2747-FCG is a tough iron base chrome/nickel/moly hot-working tool steel alloy. Alloy chemistryis balanced to provide weld metal with maximum wear resistance while still being machinable. Deposits reach maximum hardness as deposited and can be tempered to reduce stress. Weld deposits are shock-resistant and are highly resistant to heat-checking, oxidation and wear.

Postalloy 2834SPL

Postalloy 2834SPL is a high chromium hardfacing alloy that produces a high volume fraction of wear resistant chromium carbides in a tough alloy matrix that is designed for high abrasion or abrasion combined with moderate impact.

Postalloy 2850FCO

Postalloy 2850FCO is a work-hardening austenitic manganese flux-cored wire, alloyed with chromium and nickel for improved weld deposit properties over standard manganese alloys. It is designed for build-up, hardfacing and fabricating of manganese steel. Deposits are very tough, and work-harden rapidly in-service as plastic deformation occurs during impact.

Postalloy 2892SPL

Postalloy 2892SPL is a medium hardness build-up wire with excellent compressive strength. Recommended for applications where weld deposits must provide good metal-to-metal wear resistance, but still be machinable "as welded". Use on carbon and low alloy steels.

Postalloy 2892FCO

Postalloy 2892-FCO is a strong, tough, low alloy build-up wire. It can be applied to carbon and low alloy steels. Weld deposits are exceptionally sound and dense, and heavy build-ups are possible without danger of cracking.

Postalloy 2893SPL

POSTALLOY 2893-SPL is a high hardness, machinable gas-shielded hardfacing wire. It provides high compressive strengths and the wear life will far exceed conventional build-up alloys and mild steel. Weld deposits are exceptionally sound and dense, and heavy build-ups are possible without danger of cracking(preheat may be necessary for certain low alloy, higher carbon steels). Use on carbon and alloy steels

Postalloy 2893FCO

POSTALLOY 2893-FCO is a high hardness, machinable flux-cored, open-arc hardfacing and build-up wire. It provides high compressive strengths and the wear life will far exceed conventional build-up alloys and mild steel. Weld deposits are exceptionally sound and dense, and heavy build-ups are possible

Postalloy 2898SPL

Postalloy 2898-SPL is 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) .

Postally 2898FCO

Postalloy 2898-FCO is a general purpose flux-cored, open-arc hardfacing wire providing a good combination of abrasion resistance and toughness. Use to overlay carbon and low alloy steel, manganese steel, stainless steel and cast iron.

PS 133

  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, sub soilers 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.

PS 164

PS 164 is 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

Duralloy 2832

Deposits of DURALLOY 2832 are the ultimate high chromium carbide-surfacing alloys. It can be used on components subject to the most severe abrasive wear combined with low to moderate impact. It can also be used where high temperature (1100°F) wear resistance is required.

Typical applications:

crushing rolls, grinding equipment, tillage tools, shovel teeth, augers, slag-handling equipment, pipe I.D.

Techalloy NI55

Techalloy 55 is used for TIG and MIG welding of cast iron. This filler metal is extensively employed to overlay the cast iron rolls. It is also used to repair the castings. The weld metal of Techalloy 55 is harder than that of Techalloy 99. However, the machining can be accomplished by u sing carbide tipped tools. A preheat and interpass temperature of 350ºF (175ºC) minimum is recommended during welding, without which the weld and heat affected zones could develop cracks.

Hardfacing Wires

While we offer a wide variety of products for use with different welding processes, our hardfacing wires remain the focus of our business.  They are characterized by high deposition rates, great out-of-position weldability, terrific welder appeal, low smoke volume and unsurpassed wear protection.  We offer a full range of chemistries and sizes to meet any application.  Our hardfacing wires are produced on state of the art equipment, ensuring consistent chemistries from the smallest size to the largest.  Nothing is sacrificed – no short cuts are taken.

Duroweld - hardfacing electrodes

POSTALLOY 205 may be used alone, as a combination build-up and hardfacing alloy, or used as a build-up and cushion prior to overlaying with a more abrasion resistant alloy, such as 213 or 214. Weld deposit chemistries consist of chromium carbides combined in such a way as to produce extremely good abrasion resistance coupled with mild to moderate impact resistance.
