K30 Cemented Tungsten Carbide Cutter With High Hardness And Toughness

Product Description

K30 Cemented Tungsten carbide cutter with high hardness and toughness

Tungsten carbide cutter is made of tungsten carbide. Tungsten carbide is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. Tungsten steel has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which remain basically unchanged even at a temperature of 500°C. It still has a high hardness at 1000°C.

Introduction of tungsten carbide cutter

Tungsten tungsten carbide cutter is mainly made of monolithic tungsten steel as the base body, which is processed through multiple production processes.

Tungsten steel, also known as cemented carbide, is made of high-quality tungsten carbide + cobalt powder, mixed with a formula, and then pressed and sintered. 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 the manufacturing industry.

Tungsten carbide is distinguished by grain size, and can be divided into ordinary cemented carbide, fine-grain cemented carbide, sub-fine and ultra-fine-grain cemented carbide, and the newly launched double-crystal cemented carbide. According to the main chemical composition, it can be divided into tungsten carbide-based cemented carbide and titanium carbide-based cemented carbide. Tungsten carbide-based cemented carbides include three types of tungsten-cobalt (YG), tungsten-cobalt-titanium (YT) and rare carbide (YW). They have their own advantages and disadvantages. The main components are tungsten carbide (WC) and titanium carbide ( The commonly used metal bonding phase such as Tic and niobium carbide (NbC) is Co. Titanium carbide-based cemented carbide is a cemented carbide with Tic as the main component, and the commonly used metal bonding phases are Mo and Ni. Cemented carbide has high hardness (86～93HRA, equivalent to 69～81HRC) second only to diamond, good thermal hardening (up to 900～1000℃, maintaining 60HRC); high bending strength (MPa5100), good impact toughness And the chemical inertness with high corrosion resistance and other characteristics that ordinary alloy blades do not have.

Storage method of Tungsten carbide cutter

It is forbidden to write or mark on the blade with an electric engraving pen or other scratch methods to prevent damage to the blade body. The blade of the foot cutter is extremely sharp, but very brittle. In order to avoid the blade injury to personnel or accidental damage to the blade, do not touch the blade to the human body or other metal hard objects. The blades to be used shall be properly kept and stored by special personnel, and shall not be placed casually, so as to prevent the blades from being damaged or causing accidents.
