Plate shear blades see impact, work-hardening substrate and variable stock thickness. The grade, hardness and chamfer choice drive a 10× difference in service life between a mill-spec blade and a generic one. This guide covers carbon steel, stainless, high-strength and abrasion-resistant plate.
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.

A slitter knife that produces growing burr is almost always one of four things: hone growth from wear, substrate variation, line condition drift, or heat-treat quality. This article walks through the 10-minute diagnostic and the corrective action for each root cause.
Edge chipping on a paper slitter has four root causes, and each has a different fix. This article walks through the 10-minute diagnostic — visual, dimensional, hardness, line-side — and the corrective action that actually works.
