Ni- Hard 4

Material Ni- Hard #4 is a eutectic alloy solidifying into two phases at a single temperature. Because of the physical characteristic and increased alloy content, a more random and dispersed carbide structure improves toughness over standard Ni- Hard #1 compositions. C Si Ni Cr Mn Fe Mo

Brinell Hardness 600 MICROSTRUCTURE:

Diamite 4 (Ni- Hard #4) consists of a predominantly M7C3 primary carbide phase in a mostly martensitic matrix. Minor amounts of retained Austenite are also found in the matrix. Diamite 4 (Ni- Hard #4) is typically specified in the as- cast condition. Heat treatments can be applied for special applications. Click here to return to Alloy List
