Cemented Tungsten Steel Blade Used As Reamer In Wear-Resistant Parts

Tungsten steel blade is mainly made of tungsten carbide and cobalt alloy powder through metallurgical mixing, crushing, ball milling, pressing and sintering. Its main components are WC and Co. The content of tungsten carbide and Co in tungsten carbide for different purposes is different, so it has been widely used. In a wide range, cemented carbide has good hardness and toughness. It has become the most widely used cemented carbide material and is widely used in engineering and tool products.

Introduction of tungsten steel blade

Tungsten steel blade is mainly made of monolithic tungsten steel and processed through a variety of production processes.

Tungsten steel, also known as cemented carbide, is made of high-quality tungsten carbide + cobalt powder through mixing, pressing and sintering. It has high hardness, high strength, high wear resistance and high elastic modulus. It belongs to the powder metallurgy industry. As the teeth of modern industry, cemented carbide tools play a fundamental role in promoting the development of manufacturing.

According to the grain size, tungsten steel can be divided into ordinary cemented carbide, fine-grained cemented carbide, sub-fine-grained and ultra-fine-grained cemented carbide, and newly introduced double-crystal cemented carbide. According to its main chemical composition, it can be divided into tungsten carbide-based cemented carbide and titanium carbide-based cemented carbide. Cemented carbide has high hardness (86~93HRA, equivalent to 69~81hrc), second only to diamond, high thermal hardness (up to 900~1000℃, maintained at 60HRC); high bending strength (mpa5100), good impact toughness and high Corrosion resistance, chemical inertness and other characteristics that ordinary alloy blades do not have.

How to keep tungsten steel blade

It is strictly forbidden to write or mark on the blade with an electric pen or other scratching methods to avoid damage to the knife body. The cutting edge of the foot knife blade is very sharp, but very fragile. To avoid personal injury or accidental damage to the cutting edge, do not touch the cutting edge to the human body or other metal hard objects. The blades to be used should be kept and stored by specialized personnel, and should not be placed alone to prevent damage to the blades or cause accidents.
