27/06/2019· 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

Silicon Carbide Abrasive Sharpening Stones - …

Silicon Carbide Abrasive Sharpening Stones. Abrasive sharpening stones are used to sharpen the edges of metal cutting tools and debur, clean, and smooth workpieces or surfaces. Also known as a whetstone or water stone, a sharpening stone''s shape determines its use, and its surface material and grit size determine the finish it provides.

Silicon Carbide (SiC): Properties, Production

Silicon carbide, with the chemical syol SiC, is a solid industrial mineral crystalline. It is used as a semiconductor and a ceramic, commonly referred to as carborundum. SiC exists naturally in an extremely rare mineral called moissanite. Pure silicon carbides appear as colourless and transparent crystals.
