Today, Huilisheng's editor will guide you through the material properties of tungsten steel cutting blades:

Tungsten steel cutting blades are primarily made from solid tungsten carbide as the base material and are precision-engineered through multiple production processes.

Also known as carbide cutting blades, they are manufactured by mixing high-quality tungsten carbide and cobalt powders in specific formulations, followed by pressing and sintering. This process results in high hardness, high strength, excellent wear resistance, and a high elastic modulus, falling under the category of powder metallurgy. As the "teeth of modern industry," carbide tools play a foundational role in driving the development of the manufacturing sector.

Tungsten carbide can be classified based on grain size into standard carbide, fine-grain carbide, sub-fine and ultra-fine grain carbide, and the newly introduced dual-phase carbide. Based on chemical composition, it can be divided into tungsten carbide-based hard alloys and titanium carbide-based hard alloys. Tungsten carbide-based hard alloys include three categories: tungsten-cobalt (YG), tungsten-cobalt-titanium (YT), and those with added rare carbides (YW). Each type has its own advantages and disadvantages. Their main components are tungsten carbide (WC), titanium carbide (TiC), niobium carbide (NbC), etc., with cobalt (Co) commonly used as the metal binder. Titanium carbide-based hard alloys primarily consist of TiC, with molybdenum (Mo) and nickel (Ni) commonly used as metal binders.

Carbide exhibits high hardness (86–93 HRA, equivalent to 69–81 HRC), second only to diamond, excellent red hardness (maintaining 60 HRC at 900–1000°C), high flexural strength (up to 5100 MPa), good impact toughness, and high corrosion resistance with significant chemical inertness. These are characteristics generally not found in ordinary alloy blades.
