SA-MCC Premium Multiple Carbide Overlay Plate

Our SAS Global SureAlloy Multiple Complex Carbide overlay plate (SA-MCC) was developed to satisfy the various application needs of our customers. SA-MCC Overlays can be custom blended to provide material characteristics needed for specific wear resistivity. For example, if the application requires increased impact resistance and temperature rating, the blend of complex carbides would have higher levels of Molybdenum and Niobium.

Each specific blend of SA-MCC has its own specific numerical designation. This numerical designation is directly correlated to the percent of each carbide forming element found in the overlay.

These photomicrographs show electrolytically etched and dyed SA-MCC samples at both 100X and 500X. SA-MCC overlay derives its excellent properties from a combination of type MC, M2C, M7C3, and M6C carbides, which are composed of various amounts of Mo, W, V, Nb, and Cr. The formation of these carbides is controlled by SAS Global’s proprietary overlay process and metallurgical blend, which provide a balance of strength, toughness, and wear resistance.

SA6000® is the new future of overlay wear plate. The patented microstructure of SA6000 is highly refined with tightly packed complex carbides. This fine grain microstructure reduces the propagation of cracks, which results in not only superior protection from abrasion, but also unheard of impact resistance!

SA2000® is a specially formulated complex carbide overlay plate designed to generate a high concentration of small primary carbides greatly improving wear resistance over conventional chromium carbide alloys. The refined microstructure containing harder complex carbides provides greater wear resistance and improved toughness. The inert refractory carbides present also increase the temperature resistance and corrosion resistance. Up to double the service life of standard chromium carbide overlay plate.

SAS Global Engineers a smooth surface finish on all SureAlloy® Premium Weld Overlay Products. The standard SureAlloy® surface finish can be blanchard ground to provide an even lower coefficient of friction for applications with heavy material hang-up issues. This premium surface is known as RapidFlow® Premium Surface Carbide Overlay Plate. The surface is ground and polished to a 0.2 Ra Micro-Meters finish. This finish is smoother than a stainless steel 304 with 2B finish.
