POSTALLOY® Tungsten Carbide Hardfacing wires are specially engineered to ensure maximum service life of hardfaced surfaces. Hardface Technologies offers a variety of hardfacing alloys to meet your specific needs. We provide tungsten carbide hardfacing wires alloyed with various metals such as nickel, chromium, silicon and boron to create products that ensure maximum protection of your equipment in virtually any environment.

Benefits of POSTALLOY® Tungsten Carbide Hardfacing Products include:

  • Hardness up to 70 Rc
  • Easy to apply with low current
  • Unsurpassed wear and corrosion resistance

In addition to Tungsten Carbide Hardfacing wires, Postle Industries offers a complete line of Hardfacing Products engineered for maximum service life of your equipment.

Mig Tungsten Carbide
Mig Tungsten Carbide is a welding process that deposits extremely hard tungsten carbide particles (70 Rc) in the weld puddle of a hardfacing wire as it is applied.
  • Use in extreme abrasion environments
  • Incorporates intact tungsten carbide particles for maximum abrasion resistance
  • More abrasion resistant than Chromium Carbide
  • Provides 300%-800% wear life compared to typical hardfacing wires
  • Easy to apply
Mig Carbide is unsurpassed in abrasion and impact resistance when applied with POSTALLOY PS-98. This is because softer wires wear away allowing the tungsten carbide to literally fall off the wear surface. POSTALLOY PS-98, with a hardness of up to 60 Rc, prevents this from happening.

POSTALLOY® 219HD
Flux-coated Tubular Electrode alloyed with Tungsten Carbide and Chromium
When protection with tungsten carbide is needed, POSTALLOY® 219HD is an ideal choice. Weld deposits contain tungsten carbide in a chromium rich matrix for added wear and corrosion protection . Other features include:
   • 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
   • High deposition rates - up to 3 times faster than ordinary electrodes
   • Moisture resistant coating, even under severe weather or high humidity
POSTALLOY® 219HD hardfacing is a unique concept in hard facing technology and is over 90% efficient. It's tubular design offers very smooth operational characteristics and permits higher travel speeds and much higher percentages of carbide forming elements contained in the core as compared to ordinary flux-coated electrodes.

POSTALLOY® 220HD
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.

POSTALLOY® CP63070 and CP63070-M
Powder: Nickel Base Self-Fluxing Powder with Tungsten Carbide
Postalloy® CP63070-M is a nickel base self-fluxing powder alloy combined with a very special high carbon tungsten carbide grade to produce the highest amount of abrasion resistance possible. The matrix that encapsulates the carbides has a hardness of 55–60 RC.
The Tungsten Carbide in CP63070 has a very high hardness with a very dense, uniform crystalline structure.
The residual stresses are far lower than conventional tungsten carbide, providing better toughness and impact resistance.
The particles have almost no microdefects, enhancing the wettability characteristics.
The low fusing temperature of this alloy combined with cobalt-free carbides help to reduce solution alloying and melting of the carbides.
The tungsten carbide used is this product goes through an oxidation reduction process that reduces the oxidation potential of this alloy. This helps to reduce unwanted overspray and gives the operator more control of the puddle.

Postalloy® CP63070-M uses the same nickel base self-fluxing powder alloy, but with a more economical, less abrasion resistance and less impact resistant tungsten carbide. Designed for less abrasive wear environments or when maximum abrasion resistance is not required.

POSTALLOY® PS-11W

Tungsten Carbide Wire: Metal-cored, Gas-shielded

POSTALLOY®PS-11W with Reactive Core Technology™ (RCT) is a nickel base hardfacing cored wire containing a special blend of tungsten carbides for extreme abrasion as well as corrosion. The matrix is resistant to acids, bases, lye and other corrosive media. This alloy can be applied crack-free with the proper welding procedures. The alloying elements in the wire produce a higher hardness weld deposit that encapsulates and protects the carbide particles, reducing the premature wear caused by erosion to the carbide particles. As a result it achieves a considerable service life improvement in extreme applications compared to PS-10 which it has replaced. The alloy has a low melting range and features good weld ability with a smooth arc, reduces weld dilution and carbide dilution to produce a truly outstanding multi-wear wire. Also, this product has a service temperature up to 1000F (530C). Use on low carbon mild and low alloy steels, stainless, nickel and cast iron.
