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.
