SA1750CR Chromium Carbide Overlay Plate

The True Premium CRC Plate

SAS Global Corporation has over 50 years of expertise with abrasion resistant materials. During those 50 plus years SAS Global has developed a proprietary manufacturing method for producing a Chromium Carbide Overlay Wear Plate known as SA1750CR. SAS not only developed the manufacturing method, but also built and engineered the equipment. All of the alloys used in the creation of SA1750CR are custom blended by SAS Global, enabling quality control from start to finish, and insuring you receive the finest product available today.

SA1750CR sets the industry standard for controlling abrasive wear. SA7150CR is a Chromium Carbide Overlay Plate consisting of a Hypereutectic Matrix with up to 40% Chromium Carbides metallurgically fused to an appropriate steel substrate. This large amount of hard chromium carbides allows SA1750CR to thrive in environments of extremely high abrasion.

Hardness

The hardness of a SA1750CR overlay is a composite of the hard chromium carbides (1750 Vickers), with that of the tough, austenitic matrix. The macro-hardness of the overlay is 55-62 Hrc, depending on the thickness of the overlay.

The Chromium Carbide surface is comprised of a series of beads (3/4" to 1-1/2" wide) with many hairline cracks. These cracks are a natural phenomenon created during the overlay process. Cracks in the overlay are both desirable and necessary. They allow the overlay surface to be formed into complex shapes and to withstand impacts that cause other hard materials to fracture.

A mild steel substrate is used for all stock plate. This backing material plays an integral part to the plate’s formability and impact resistance. A variety of substrates, such as stainless steels, nickel alloys and quenched & tempered steels are used in manufacturing the SA1750CR overlay plate. Custom blending alloys for specific overlay properties are utilized by many customers. SAS engineers can help you determine the perfect substrate and alloy combination for your specific application.
