Chef cutter and fruit cutter composite material

The technical scheme of the invention is that the cutter blade of the chef cutter/fruit cutter uses a VG-10 Wusheng special stainless steel (1), the thickness is 30-50% of the whole thickness, the weight accounts for 25-50% of the whole cutter weight, the chef cutter/fruit cutter body uses a high-quality martensite 3CR13 stainless steel (2), the cutter blade steel is sealed and wrapped in the 3CR13, 1180-1220 high-pressure and high pressure metallurgical compounding is performed to form a cutter billet composite material (3), and the composite material is subjected to a heat treatment to achieve the cutter body steel hardness of HRC43-48 and the cutter blade steel hardness of HRC60-62. According to the present invention, although the weight of the VG-10 Wusheng special stainless steel accounts for 25-50% of the whole weight of the cutter, the chef cutter/fruit cutter with advantages of high toughness, high strength, sharp cutter blades, rust resistance, corrosion resistance, high performance, low cost and goo
