Tag: blade material selection

A side-by-side comparison of high-speed steel and tungsten carbide for industrial machine knives — covering hardness, toughness, cost, edge retention and the substrates each material was actually designed to cut.

Stainless steel work-hardens under the cut, and the wrong blade grade will see service life drop by 3–5×. This selection guide walks through the substrate family, the right steel grade, the right edge prep, and the heat-treat spec for cutting 304, 316, 430 and 17-4PH.
