Grapple Hook
Grapple Hook
Postalloy® 210HD is formulated with a high percentage of Chromium Carbide producing a tubular hardfacing electrode that is highly resistant to abrasion with mild or moderate impact. Weld deposits are smooth and take on a high polish to resist sliding particle abrasion. It can be apllied to carbon and alloy steels, as well a cast iron.

High Compressive Strength - Deposits do not tend to shatter and spall off under conditions of high impact. Ideal for gouging abrasion.

Hardness at Elevated Temperatures - The hardness and wear resistance of Postalloy 210HD is maintained up to 1000°F(538°C).

Welding characteristics are outstanding - Postalloy® 210HD can be used on any type of welding machine, either AC or DC, in both flat and vertical positions.

Welding ProcedureDue to lower dilution, DC polarity will produce a higher first pass hardness and is also ideal for thin sections. Remove all damaged or fatigued metal. Preheating is generally not required. However, for high carbon or alloy steels and cast iron, a preheat of approximately 400˚F (204˚C) is required.
