POSTALLOY® 215HD hardfacing electrodes, available in 1/4”(6.0mm) and 1/2”(12.5mm), are a unique concept in hardfacing technology. They are tubular, permitting higher travel speeds and much higher percentages of carbide forming elements contained in the core than with ordinary flux-coated electrodes. 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). Due to its unique tubular design, POSTALLOY 215HD offers very smooth operational characteristics. Both the 1/4” and 1/2” diameters will fit standard electrode holders. Other outstanding features are: • 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. POSTALLOY 215HD is over 90% efficient.. • Low amperage - 1/4”(6.0mm) from 80 amps, 1/2”(12.5mm) from 180 amps. • High deposition rates - up to 3 times faster than ordinary electrodes. • Moisture resistant coating, even under severe weather or high humidity.
