Grade GW8120 Performance Profile

Operators running steel, stainless steel, cast iron, carbon steel with the Chang Cheng GW8120 typically report stable wear progression rather than catastrophic edge loss. The tin system is the reason: it slows abrasion at the rake face while keeping the substrate from softening at the cutting zone.
