The alloy-inlaid long blade is composite rolled and can be used for general cutting. The original grains are refined and have strong resistance to chipping. There are no transitions, gaps and other defects in the combination of the blade steel and the knife body, and the cutting edge will not peel off, ensuring the service life. The selected materials include W18Cr4V, W5, W6, SKH, HSS, SKH-51 and other high-speed steels, with added high-speed steel elements such as tungsten, molybdenum, vanadium, cobalt, etc., which are wear-resistant, high toughness, sharp and durable. Mainly used for slitting steel plates, films, non-woven fabrics, electronic aluminum foil, copper foil, tapes, wood industry, leather, food, and pharmaceutical blades.
