Blank Material Selection

HSS saw - blades use high - performance high - speed steel (HSS) as the blank material, with alloying elements such as tungsten, molybdenum, chromium, and vanadium as the core components. Tungsten and molybdenum endow the saw - blades with red - hardness, enabling them to maintain high hardness and wear - resistance even at a high temperature of 600°C. Chromium enhances the oxidation and corrosion resistance, extending the service life. Vanadium refines the grains, improves the strength and toughness, and reduces the risk of fracture. These material characteristics make HSS saw - blades perform excellently in medium - and low - speed metal cutting, especially suitable for the processing of workpieces with high - precision and high - durability requirements.

TCT saw-blade blanks adopt a unique combination: the cutting head is made of cemented carbide (tungsten carbide-cobalt alloy), featuring high hardness and strong wear resistance for high-speed cutting of various metals; the substrate uses high-quality alloy steels such as spring steel, which offers excellent toughness and fatigue resistance to ensure overall stability. The two components are bonded by high-temperature welding, integrating high-hardness cutting performance with strong toughness, making them suitable for high-speed and large-batch metal processing.
