Railroad Engineered Hardfacing and Build-Up Welding Alloys
POSTALLOY® Hardfacing Alloys for Railroad Frogs, Switches and other track and rail components.
POSTALLOY® Hardface Welding Alloys for rail and track repair are specially engineered to ensure maximum service life of hardfaced surfaces. Hardface Technologies offers a variety of hardfacing alloys that become harder and tougher during use to withstand the constant pounding of railroad cars. Benefits of POSTALLOY® Hardfacing Alloys include:
  • Excellent wear and impact resistance
  • Easy weldability
  • Provide support for wheels and passageways for their flanges

Hardface Technologies has great support too! For complete application procedures please contact Postle Industries at (216)265-9000.

       POSTALLOY® 301
 Flux-coated electrode

Product Description

POSTALLOY® 301 is a high strength, ductile, crack resistant welding alloy specifically designed for welding problem steels such as, low alloy, high carbon or crack sensitive tool steels. Ideal for welding dissimilar steels- low alloy, spring steels, carbon steels, tool steels. The benefits of POSTALLOY® 301 include:
• Excellent joining characteristics - With the combination of balanced alloy chemistry and high strength, crack resistant weld deposits, the capability to weld dissimilar problem steels is outstanding.
• Carbon has no adverse effects - Carbon, the cause of most problems associated with weld cracking and hard spots, is rendered harmless.
• Acts as a shock absorber during operation - Since POSTALLOY® 301 does not respond to heat-treatment and remains ductile, it has the ability to withstand heavy impact or shock loading.

301 Data Sheet
       POSTALLOY® FrogTuff
 Flux-coated electrode

Product Description

Ideal for use on manganese steel. Under severe impact, such as hammering or pounding, deposits quickly become tougher and harder. Produces high-strength, non-cracking deposits that are tough, ductile and work-harden rapidly. The high yield strength reduces mushrooming from impact. POSTALLOY® FrogTuff may be used alone, as a combination build-up and hardfacing alloy, or used as a build-up and cushion prior to overlaying.

POSTALLOY® FrogTuff is an all-position crack-free electrode for joining or overlaying for high impact. It operates on either AC or DC reverse; the arc is smooth and stable with low spatter loss. Slag removal is easy.

       POSTALLOY® RailTuff
 Flux-coated electrode

Product Description

POSTALLOY® RailTuff is a non-cracking build-up electrode in the machinable range of hardness providing wear resistance that is far superior to low and medium carbon steel and low alloy steels.

Deposits are extremely tough and have a high resistance to impact and deformation and are not subject to spalling or roll-over. In addition, deposits are dense, crack-free and porosity-free.
