Validate Raw Material and Heat Treatment
Blade performance starts with raw materials. Reputable suppliers use certified HSS, D2 or tungsten carbide with strict vacuum heat treatment to balance hardness and toughness. Cheap vendors often use inferior steel, leading to rapid dulling and edge chipping. All Guangchuan industrial blades come with full material traceability for consistent, long-lasting performance.
