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.

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® FrogTuff-FCO is a non-cracking high alloy austenitic manganese steel open-arc welding wire for joining, build-up or hardfacing. Produces high-strength, crack-free deposits that are tough, ductile and work-harden rapidly. The high yield strength reduces mushrooming from impact.

Postalloy® RailTuff-FCO is a non-cracking strong, tough, low alloy open-arc build-up wire. It can be applied to carbon and low alloy steels. Weld deposits are exceptionally sound and dense, and heavy crack-free build-ups are possible.
