HC 1650 M7C3

HC 1650 is our most commonly used wear plate.  It is a fine grained austenitic chromium carbide, general purpose grade that provides a solution for most applications.  The refined hyper-eutectic microstructure in the overlay provides excellent wear resistance against a wide range of wear mechanisms in both mobile earth moving equipment and fixed plant applications of MEDIUM WEAR ABRASION and LOW to MEDIUM IMPACT.  Complies to BHP Spec 1.

Overlay Material Type

The overlay material is an austenitic chromium carbide alloy consisting of a uniform, high density distribution of fine primary M7C3 carbides in a matrix of carbide and austenite as described in AS2576-2355.

Volume Fraction of Carbides > 35%

Vickers Macro Hardness (HV) 650

HRC 56.5

Backing Plate

The standard A36 steel backing plate is ideal for multiple installations methods.  The backing plate is in a variety of thicknesses to suit all applications.

Metallurgical Testing Type

Complies with the ASTM G65 dry sand rubber wheel test procedure with less than 0.3 grams loss.

Thermal Expansion Relief Cracks

The HC 1600 series of wear resistance steel has inherent cracks due to the metallurgical structure of the high chrome.  These cracks are not structural cracks that will cause the plate to break.  Instead, these cracks are thermal expansion relief cracks to enhance bending and rolling under compression. These thermal expansion relief joints are common in most ALL CCO to wear plates and are commonly visible.
