Understanding Steel:The Rockwell Hardness Scale RECOIL Oct 14, 2016 · The Rockwell Scale is used to determine the hardness of a material, and part C specifically refers to steel. The hardness of a steel is determined by the heat treatment of the blade. In simple terms, the higher the number, the harder the steel. However, one steel is not better than another simply because it is harder.

    Why HSS type of steel is being used to make knives

    High-speed steel (HSS or HS) is a subset of tool steels, commonly used in tool bits and cutting tools. It is often used in power-saw blades and drill bits. It is superior to the older high-carbon steel tools used extensively through the 1940s in that it can withstand higher temperatures without losing its temper (hardness). high speed tool data - ICS Cutting ToolsHardness Rockwell C:Term:M1.80:1.50:8.00:4.00:1.00:63-65 "HSS" M2.85:6.00:5.00:4.00:1.90:63-65 "HSS" M7:1.00:1.75:8.75:4.00:2.00:63-65 "HSS" M50.85.10:4.25:4.00:1.00:63-65 "HSS"
