Silicon Carbide SiC Material Properties - Accuratus
Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. This produces a very hard and strong material. Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800°C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C.

GRINDING FOR TOOLMAKING
Grinding low-alloy tool steels seldom presents any difficulties. When grinding high-alloy tool and high-speed steels with high carbide content, however, problems can easily occur. For this reason, the grinding parameters must be selected carefully. The higher the wear resistance of a steel, the more difficult it is to grind.
