2019-6-27 · The SiC stone will do better on ''high carbide '' steels in particular. ''High carbon'' steels won''t necessarily be an issue with most any stone type, if they don''t have a lot of hard carbide content. By ''carbides'', I''m talking about chromium carbides, vanadium carbides, tungsten carbides, etc., which add a lot of wear resistance to the steel, because these carbides are 2X or more harder than the
What is the Silicon Carbide (SiC) Silicon carbide has been the most widely used material for the use of structural ceramics. Characteristics such as relatively low thermal expansion, high force-to-weight radius, high thermal conductivity, hardness, resistance to abrasion and corrosion, and most importantly, the maintenance of elastic resistance at temperatures up to 1650 ° C, have led to a
Silicon carbide is a very popular abrasive in modern lapidary owing to its durability and the relatively low cost of the material. It is, therefore, crucial to the art industry. In the manufacturing industry, this compound is used for its hardness in several abrasive machining processes such as honing, grinding, water-jet cutting, and sandblasting.
