AMA WEAR 814H Hard Facing

 Let the Hard Facing take the punishment away from your machine.

AMA WEAR 814H electrode is an enhanced alloy for HARD FACING applications requiring heat, spalling, and severe crushing resistance. Made specifically for shears you will find many other uses for this product.

A superior all position electrode, designed for hot work applications, it features special alloying and fluxing agents producing the ultimate in homogenous porous-free high-density weld deposits.

Primarily used for overlays and complete impression welds on press forging die. Other uses that are suited for this material include upsetter insert dies, hammer dies, wearing surfaces, shears, and all A.I.S.I.H series hot work tool steels.

Technical Data:

Alloy Type: Cr-Ni-Mo-W
Hardness: RC 42-44
Machinability: By Grinding Only

For touch-up repairs on forging dies, a localized preheat of 400°F is sufficient with a slow cool. Use AC or DC reverse polarity after grinding or scarfing defective areas for repair applications. Be sure to remove all oxides and other foreign matter from the area before welding. For full impression welds on-die blocks, preheat to 900°F. Maintain temperature during welding. After welding, cool in still air to 300°F to obtain ultimate grain refinement and complete transformation on austenite in weld deposit. Temper at 1050° at one hour per inch on thickness at temperature.
