| Postalloy® 2865-FCO | Product Description | Typical Applications |
|---|---|---|
| Postalloy Wire: Flux-cored, Open-arc |
Postalloy® DuraMang™ 2865-FCO is a flux-cored, open-arc hardfacing wire that deposits fully austenitic chromium-manganese weld metal. It can be used equally well for joining and build-up/surfacing of carbon, low alloy and manganese steels. Weld deposits have an excellent combination of weld metal strength, ductility and hardness. Work-hardens rapidly under repeated impact. Deposits have very good frictional wear properties and are ideal for railroad applications requiring metal-to-metal wear resistance. Ideal as a cushioning or buffer layer on manganese steel parts that will be repeatedly rebuilt. Since it will not embrittle until 1000°F (538°C), it will act as an insulator to the manganese base metal in helping it keep below 500°F (260°C) during the welding operation. | Pulverizing hammers Cone and roll shells |

Postalloy® DuraChrome™ 2834-SPL 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. Deposit will polish in service and is heat resistant to 1000°F (538°C). Use on low carbon mild steel, manganese, stainless, and low alloy steels. |
| Postalloy® 2836-MCO | Product Description |
|---|---|
| Postalloy Wire: Metal-cored, open arc or gas-shielded. Deposits are slag-free. |
Postalloy® 2836-MCO is a high hardness multi-carbide hardfacing alloy that resists severe abrasion, including high stress grinding, low stress scratching and gouging abrasion. It maintains its hardness and wear resistance up to 1300°F (700°C). The chemistry is highly tolerant of dilution. One layer will easily outwear two layers of ordinary chrome carbides and in some applications the wear is equal to tungsten carbide. Use on low carbon mild steel, manganese, stainless, and low alloy steels. |
| Postalloy® 2850-FCO | Product Description |
|---|---|
| Postalloy Wire: Flux-cored, open-arc |
Postalloy® DuraMang™ 2850-FCO is a work-hardening austenitic manganese flux-cored, open-arc wire, alloyed with chromium and nickel for improved weld deposit properties over standard manganese alloys. It is designed for buildup, hardfacing and fabricating of manganese steel. Deposits are very tough, and work-harden rapidly in service as plastic deformation occurs during impact. |
| Postalloy® 2865-FCO | Product Description |
|---|---|
| Postalloy Wire: Flux-cored, Open-arc |
Postalloy® DuraMang™ 2865-FCO is a flux-cored, open-arc hardfacing wire that deposits fully austenitic chromium-manganese weld metal. It can be used equally well for joining and build-up/surfacing of carbon, low alloy and manganese steels. Weld deposits have an excellent combination of weld metal strength, ductility and hardness. Work-hardens rapidly under repeated impact. Deposits have very good frictional wear properties and are ideal for railroad applications requiring metal-to-metal wear resistance. Ideal as a cushioning or buffer layer on manganese steel parts that will be repeatedly rebuilt. Since it will not embrittle until 1000°F (538°C), it will act as an insulator to the manganese base metal in helping it keep below 500°F (260°C) during the welding operation. |
| Postalloy® 2892-MCG | Product Description |
|---|---|
| Postalloy Wire: Metal-Cored, Gas-shielded |
Postalloy® DuraBuild™ 2892-MCG is a medium hardness build-up welding 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® 217HD | Product Description |
|---|---|
| Postalloy Flux-coated Tubular Electrode |
Postalloy® 217HD is modified Chromium Carbide tubular hardfacing electrode, alloyed with Niobium and a small addition of Molybdenum. The microstructure has very fine carbides which give improved wear, errosion and impact resistance over traditional Chromium Carbides. It is designed for applications that require more abrasion resistance than Postalloy® 215HD. The Carbide concentration is denser and slightly harder but less brittle than Postalloy® 215HD providing a better, more wear-resistant surface. |
| Postalloy® 218HD | Product Description |
|---|---|
| Postalloy Flux-coated Tubular Electrode |
Postalloy® 218HD produces a multi-carbide weld deposit that resists many types of wear. The weld-deposit. is a tightly packed, dense, inter-connected network of chromium carbides, vanadium carbides, molybdenum carbides, niobium carbides and tungsten carbides. Weld deposits offer exceptional wear resistance to general abrasion, high stress grinding, low stress scratching and erosion. Impact resistance is limited. This alloy may also be used at elevated temperatures up to 1300°F (700°C). First pass hardness is greater than other hardface electrodes - 65Rc on mild steel. Other outstanding features include: |
| Postalloy® 220HD | Product Description |
|---|---|
| Postalloy Flux-coated Tubular Electrode alloyed with Tungsten Carbide and Chromium Carbide | Postalloy® 220HD is a proprietary blend of Tungsten Carbide with a small addition of Chromium Carbide. It produces a very smooth weld deposit with improved impact resistance over pure Tungsten Carbide. The unique blend of Tungsten Carbide in a Chromium rich matrix also provides some corrosion protection but primarily helps to provide a high polish in service to reduce the coeffcient of friction. When protection against severe abrasion, with limited impact, is needed, Postalloy® 220HD is an ideal choice. • Easy out-of-position weldability with the 1/4" diameter • Excellent AC or DC operation, even on a "buzz box" • Low amperage and high metal recovery - no slag to chip. Postalloy® 220HD is over 90% efficient. • High deposition rates - up to 3 times faster than ordinary electrodes • Moisture resistant coating, even under severe weather or high humidity |
