| POSTALLOY® PS-9 and PS-10 | Product Description | Typical Applications |
|---|---|---|
| Postalloy Metal-cored, gas-shielded Deposits are slag-free. |
POSTALLOY® PS-9 & PS-10 are tungsten carbide, nickel base hardfacing wires designed to resist severe abrasion but unlike traditional tungsten carbide wires, they absorb more impact without fracturing. These alloys can be applied crack-free with the proper welding procedures. These alloys are great for parts that are repeatedly hardfaced and are prone to spalling. Because of the unique chemistry, Tungsten-Carbide-Nickel-Chromium-Silicon-Boron, they also have excellent resistance to erosive wear, frictional wear, corrosive wear, and maintain their hardness, even at temperatures of 1100°F (565°C). Weld deposits contain over 50% fully fused, pre-alloyed carbides. The alloying elements in these wires 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-9 & PS-10 have very good weldability and a very soft arc, this, in combination with the nickel matrix, reduces weld dilution and carbide dilution to produce truly outstanding multi-wear wires. POSTALLOY® PS-9 is softer, 40-45 Rc, with a tougher matrix than PS-10 for applications that require more toughness. It has the same carbide hardness and concentration. | Processing equipment Mixer blades Feed screws Oil and gas drilling Down hole tools Stabilizers Dredging equipment Cutter heads Shredding Hammers Wear ringsPOSTALLOY® PS-9 and PS-10 |

|---|---|---|
| Postalloy Metal-cored, gas-shielded Deposits are slag-free. |
POSTALLOY® PS-9 & PS-10 are tungsten carbide, nickel base hardfacing wires designed to resist severe abrasion but unlike traditional tungsten carbide wires, they absorb more impact without fracturing. These alloys can be applied crack-free with the proper welding procedures. These alloys are great for parts that are repeatedly hardfaced and are prone to spalling. Because of the unique chemistry, Tungsten-Carbide-Nickel-Chromium-Silicon-Boron, they also have excellent resistance to erosive wear, frictional wear, corrosive wear, and maintain their hardness, even at temperatures of 1100°F (565°C). Weld deposits contain over 50% fully fused, pre-alloyed carbides. The alloying elements in these wires 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-9 & PS-10 have very good weldability and a very soft arc, this, in combination with the nickel matrix, reduces weld dilution and carbide dilution to produce truly outstanding multi-wear wires. POSTALLOY® PS-9 is softer, 40-45 Rc, with a tougher matrix than PS-10 for applications that require more toughness. It has the same carbide hardness and concentration. | Processing equipment Mixer blades Feed screws Oil and gas drilling Down hole tools Stabilizers Dredging equipment Cutter heads Shredding Hammers Wear ringsPOSTALLOY® PS-9 and PS-10 |

Abrasion Resistant Wires
| POSTALLOY® PS-9 and PS-10 | Product Description |
|---|---|
| Postalloy Metal-cored, gas-shielded Deposits are slag-free. |
POSTALLOY® PS-9 & PS-10 are tungsten carbide, nickel base hardfacing wires designed to resist severe abrasion but unlike traditional tungsten carbide wires, they absorb more impact without fracturing. These alloys can be applied crack-free with the proper welding procedures. These alloys are great for parts that are repeatedly hardfaced and are prone to spalling. Because of the unique chemistry, Tungsten-Carbide-Nickel-Chromium-Silicon-Boron, they also have excellent resistance to erosive wear, frictional wear, corrosive wear, and maintain their hardness, even at temperatures of 1100°F (565°C). Weld deposits contain over 50% fully fused, pre-alloyed carbides. The alloying elements in these wires 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-9 & PS-10 have very good weldability and a very soft arc, this, in combination with the nickel matrix, reduces weld dilution and carbide dilution to produce truly outstanding multi-wear wires. POSTALLOY® PS-9 is softer, 40-45 Rc, with a tougher matrix than PS-10 for applications that require more toughness. It has the same carbide hardness and concentration. |

| POSTALLOY® 2836-SPL | Product Description |
|---|---|
| Postalloy Metal-cored, open arc or gas-shielded. Deposits are slag-free. | POSTALLOY® 2836-SPL 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 1400°F (760°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 carbon, manganese, 300 series stainless and low alloy steels. |
| POSTALLOY® 2850-FCO | Product Description |
|---|---|
| Postalloy Flux-cored, open-arc | Postalloy® 2850-FCO 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 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 Flux-cored, Open-arc | POSTALLOY® 2865-FCO is a flux-cored hardfacing wire that deposits fully austenitic chromium/manganese weld metal. It can be used equally well for joining and buildup/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-SPL | Product Description |
|---|---|
| Postalloy Metal-Cored, Gas-shielded Deposits are slag-free. Also available as a flux-cored, open-arc wire - Postalloy 2892-FCO |
Medium hardness buildup 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. |
Electrodes
| POSTALLOY® 215HD | Product Description |
|---|---|
| Postalloy Electrode | POSTALLOY® 215HD is a chromium carbide tubular electrode. It's tubular structure permits higher travel speeds and much higher percentages of carbide forming elements contained in the core than with ordinary flux-coated electrodes. Due to its unique tubular design, POSTALLOY® 215HD offers very smooth operational characteristics and is over 90% efficient. All of the 1/4", 3/8" and 1/2" diameters will fit standard electrode holders. • Easy out-of-position weldability with the 1/4" diameter • Excellent AC or DC operation, even on a "buzz box" • High metal recovery - no slag to chip • Low amperage and high deposition rates - up to 3 times faster than ordinary electrodes • Moisture resistant coating, even under severe weather or high humidity. 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. Deposits take on a high polish to resist sliding particle abrasion and will maintain good hot hardness up to 1000°F (538°C). |
