Hook-shaped blades are made of various materials, and different materials determine the performance and applicable scenarios of the blades.
Metal materials
Stainless steel: Stainless steel is a common material for making hook-shaped blades. For example, BG42 steel is a new type of martensitic steel. This steel contains 1.15% carbon, 15% chromium, 4% molybdenum, and 1.20% vanadium. It has both the excellent corrosion resistance of stainless steel and the wear resistance and red hardness of high-speed steel, and is suitable for making various knives, including hook-shaped blades. Martensitic stainless steels such as 4Cr, 5Cr, 6Cr, and 9Cr may also be used to make hook-shaped blades. Hook-shaped blades made of these stainless steel materials have good corrosion resistance and are suitable for use in some environments that may be exposed to moisture or corrosive substances, such as cutting tools in food processing, marine operations, and other scenarios.
High-speed steel: High-speed steel is a widely used tool material in modern times because of its high bending strength and impact toughness, as well as good machinability. It can also be used to make hook-shaped blades. It can withstand high cutting speeds and pressures, and can maintain good performance when cutting materials with higher hardness. It is often used to make hook blades in industrial cutting tools.
Carbide: Carbide indexable inserts have been coated with titanium carbide, titanium nitride, aluminum oxide hard layers or composite hard layers by chemical vapor deposition. This material has very high hardness and excellent wear resistance. It is often used to make hook blades that need to maintain sharpness for a long time. For example, in the metal processing industry, hook blades for cutting metal materials may use carbide materials.
Other materials
Ceramics: Hook blades made of ceramic materials have the characteristics of high temperature resistance, corrosion resistance and wear resistance. For example, metal ceramic blades, which are composite materials of ceramics and metals made by powder metallurgy, have the toughness, high thermal conductivity and good thermal stability of metals, and have the characteristics of ceramics. However, ceramic blades also have the disadvantages of insufficient toughness and poor thermal conductivity, and have certain limitations in usage scenarios.
