Postalloy®
Description
Postalloy® 243HD is modified Chromium Carbide tubular hardfacing electrode, alloyed with Niobium and a small addition of Molybdenum. The micro structure has very fine carbides which give improved wear, erosion and impact resistance over traditional Chromium Carbides. It is designed for applications that require more abrasion resistance than Postalloy® 215HD. The Carbide concentration is denser and slightly harder but less brittle than Postalloy® 215HD providing a better, more wear-resistant surface.
• Easy out-of-position weldability with the 1/4" diameter
• Excellent DC operation.
• High metal recovery - no slag to chip. Postalloy® 243HD is over 90% efficient.
• Low amperage
• High deposition rates - up to 3 times faster than ordinary electrode
• Moisture resistant
