As nouns the difference between steel and carbide is that steel is (uncountable) an artificial metal produced from iron, harder and more elastic than elemental iron; used figuratively as a symbol of hardness while carbide is (chemistry) any binary compound of carbon and a more electropositive element As a adjective steel is made of steel As a verb steel.

The Rockwell hardness number is not the same as the calculated depth differential measurement Softer metals allow for deeper penetration than harder metals, so the B - A value will always be higher on soft metal test subjects than hard metals The Rockwell hardness scale number appears inverse to the depth differential calculation.

Jun 24, 2017· I realize that there are different techniques for binding carbide into a final tool shape, however by question is on a lower chemistry level Carbide by it's strict definition is a binary compound of carbon with a lower electro-negativity element So in theory there are many types of carbide: boron carbide, calcium carbide, tungsten carbide etc.
