K-TECK OEM NIOBIUM
The Directional High Chrome entry level K-TECK NIOBIUM wear plate is a specific purpose of wear plate to increase life cycle over traditional chrome carbide wear plate with medium impact. More suited to fixed plant applications with -150 ore size is typically seen for MEDIUM WEAR ABRASION with MEDIUM IMPACT application’s. The matrix structure is a Austenitic high chrome carbide saturation of more than 35% of chrome, meets the ASTM G65-04 dry sand rubber wheel test of less than 0.26 grams loss.
Wear Plate Specifications
K-TECK wear-resistant steel (WRS) is a Bi-metallic hard-facing surface of up to 700 HV of the hardness of HYPER EUTECTIC chemistry bonded to Mild steel A36 backing plate for easy methods of installation. OEM series sheet size 9.180’ x 6.700’.
A36 Backing Plate Material
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.
Overlay Material Type
The K-TECK OEM series is a high saturation of M7C3 carbides of an austenite matrix and complies with the AS2576-2355 STD.
Metallurgical Testing Type
The K-TECK series of wear-resistant steel complies with the ASTM G65 sand wheel test procedure with a chromium carbide of M7C3 saturation with less than 0.26 grams loss.
Thermal Expansion Relief Cracks
The K-TECK 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. These cracks are Thermal expansion relief cracks and enhance bending and rolling under compression. These thermal expansion Relief joints are common in most ALL CCO wear plates and is commonly visible.
K-TECK Niobium is ideal for impact application like fixed plant chutes and screens.
