Cemented Carbide Slitting Blades

For ordinary carbon steel strip (cold-rolled/hot-rolled), Cr12MoV or SKD-11 blades are recommended, used with standard round blades or paired blades. Their Rockwell hardness is HRC 58–60. These blades offer excellent toughness, wear resistance, and stable service life, making them suitable for high-volume, routine slitting operations.

For stainless steel strip (304, 316, 430), Cr12MoV1 or D2 blades are recommended, used with round blades or paired blades. The hardness should be controlled at HRC 60–62. These blades offer strong wear resistance, are less prone to chipping, and achieve burr-free and non-burring slitting results.

For soft non-ferrous metals such as aluminum, copper, and brass, high-speed steel (HSS) or alloy tool steel blades are recommended, used with precision-ground round blades. This ensures a smooth cut surface and effectively reduces material adhesion to the blade and surface scratches.

For galvanized and color-coated strips, Cr12MoV material blades are selected and used with mirror-polished round blades; the hardness is HRC 58–60, and the surface is nitrided or mirror-polished; this can effectively protect the coating on the strip surface and avoid zinc loss, paint scratches and other issues during the slitting process.
