Slotted Slitting Blade - Carbon Steel
SK5 Carbon Steel — 57x19mm
High carbon industrial slotted slitting blade. Unlike ordinary razor blades, manufactured from special steel alloy with high carbon content (0.85-1.00% C). Heat treatment in controlled atmosphere furnaces (austenitizing + quenching + tempering) achieves homogeneous martensitic microstructure. The slotted design enables quick and secure machine mounting through the central slot. Precisely ground at optimal 22° edge angle.
- High carbon content (0.85-1.00%)
