POSTALLOY®
221HD
Description
POSTALLOY® 221HD is a Tungsten Carbide based product with no Chromium Carbide. It produces a very smooth weld deposit with improved impact resistance over pure Tungsten Carbide. The unique product also provides some corrosion protection but primarily helps to provide a high polish in service to reduce the coefficient of friction. When protection against severe abrasion, with limited impact, is needed, POSTALLOY® 221HD is an ideal choice.
• 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. POSTALLOY® 221HD is over 90% efficient.
• High deposition rates - up to 3 times faster than ordinary electrodes
• Moisture resistant coating, even under severe weather or high humidity POSTALLOY® 221HD is slightly less brittle than 220HD.
