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.

A plate shear blade that cracks at the edge is almost always one of four things: chamfer too small, hardness too high, blade gap wrong, or plate out of spec. This article walks through the diagnostic and the fix for each, with a field case for stainless, mild and AR plate.
