Abrasion Resistant and NI-Hard Casting Foundry

in Knoxville, TN

Abrasion Resistant Irons, such as Ni-Hard Iron, are specialized alloys engineered for extreme wear conditions. These irons contain a low percentage of silicon and are typically alloyed with elements like nickel and chromium to enhance their hardness and durability. Unlike other cast irons, Abrasion Resistant Irons have very little graphite. Instead, most of the carbon exists in the form of iron carbides, which results in a material that is exceptionally hard and highly wear resistant. This structure also makes the metal quite brittle and often difficult or impossible to machine using conventional methods. Abrasion Resistant Irons are best suited for applications involving continuous friction, surface erosion, or material flow under high stress. They are commonly used in mining, cement processing, and other industrial environments where long-lasting performance is critical and impact loads remain minimal.

Typical Applications

• Pipes and Elbows – Conveying highly abrasive materials
