Tungsten steel, also known as hard alloy, is a high-strength alloy material made by mixing tungsten, cobalt, carbon, and other metal elements. Tungsten steel has extremely high hardness, can withstand high temperatures, wear resistance, and also has good corrosion resistance. The processing of tungsten steel is difficult, but once successfully processed, it can be used to manufacture high-speed drills, cutting tools, molds, etc.

2. White steel

The main components of white steel are carbon and chromium, and the chromium content is relatively high, usually above 12%. White steel has a high hardness and excellent grinding performance, mainly used in the manufacturing of saw blades, screwdriver heads, nuts, and bearings.

二、 The difference between tungsten steel and white steel

Although tungsten steel and white steel are both metal materials, there are some differences in their composition, characteristics, and application fields.

1. Differences in ingredients

The main components of tungsten steel are tungsten, cobalt, carbon, nickel, etc., while the main components of white steel are carbon and chromium, with chromium content usually exceeding 12%. Therefore, the different components of the two determine their performance and application fields.

2. Characteristics and Differences

Tungsten steel has excellent hardness, toughness, wear resistance, and corrosion resistance, but its processing difficulty and cost are relatively high. White steel is relatively easy to machine and has good grinding performance, but its hardness and corrosion resistance are not as good as tungsten steel.

3. Differences in application fields

Due to the different compositions and characteristics of the two materials, their applications in industrial manufacturing also have their own strengths. Tungsten steel is mainly used for manufacturing high-speed drills, cutting tools, molds, etc., while white steel is used for manufacturing saw blades, screwdriver heads, nuts, bearings, etc.

三、 How to correctly distinguish tungsten steel and white steel

1. Observe the appearance

The appearance of tungsten steel is mostly gray white, sometimes appearing dark gray and black, usually with a metallic luster. The color of white steel is usually white or dark gray, and it also has a luster.

2. Testing hardness

The hardness of tungsten steel is usually between 60-70HRC, while the hardness of white steel is between 45-55HRC. Therefore, by using a hardness tester to test the hardness of the material, it is possible to quickly determine whether it is tungsten steel or white steel.

3. Check for magnetism

Tungsten steel is generally non magnetic, while white steel is magnetic. Therefore, a magnetic detector can be used to distinguish between these two materials.

The hardness of a diamond carving knife can be measured like this

In the jewelry processing, diamond engraving knife is more often will use to the tool, like our car flower knife, hand batch knife, cnc CNC tools and other tools can be diamond engraving knife. We know that the hardness of diamond is incomparable to other objects in nature, the hardness of the tool in our choice of tool will also be taken into account, next we look at the diamond engraving knife tool hardness measurement method and influence factors. 　　The hardness of the tool is tested with Rockwell hardness tester. Steel props to detect HRC hardness, carbide manufactured tools to detect HRA hardness, PHR series portable Rockwell hardness tester is very suitable for testing tool hardness. The weight of the instrument is 0.7kg, the accuracy is the same as that of the desktop machine, and it can be tried like a micrometer, which is very convenient no matter using and carrying. 　　There are many factors that affect the quality of diamond engraving knives and other cutting tools. Among them, hardness is one of the important factors to determine the good or bad of the tool. The hardness of the tool is determined by the material, different materials determine the different hardness. The materials used to make tools are generally: diamond, tungsten carbide, high-speed steel, alloy tool steel, etc. The hardness of the tool is generally between 56(58)-63HRC. 　　The material of the tool 　　When the tool material hardness is high, the wear resistance is also high. However, the higher the hardness of the tool material, the lower its flexural strength and impact toughness. The following is a brief description of the two materials used to make tools. High-speed steel, which is still one of the most widely used tool materials due to its high flexural strength and impact toughness, as well as its good machinability. 　　Coated tools, with high surface hardness, good wear resistance, stable chemical properties, heat and oxidation resistance, small friction factor and low thermal conductivity and other characteristics, coated tools cutting than uncoated tools to improve tool life by more than 3 to 5 times, improve tool cutting speed 20% to 70%, improve machining accuracy 0.5 to 1 level, reduce tool consumption costs 20% to 50%. 　　Therefore, coated tools have become the symbol of modern cutting tools, and the proportion of use in tools has exceeded 50%. At present, various cutting tools used in cutting processing, including turning tools, boring tools, drills, reamers, broaches, taps, thread combs, hobbing heads, milling tools, forming tools, gear hobs and shaper cutters, etc. can be coated to improve their use performance. 　　There are four types of coated tools: coated HSS tools, coated carbide tools, and coated tools on ceramic and superhard material (diamond or cubic boron nitride) inserts. However, the first two types of coated tools are the most used. The coating on ceramic and superhard material inserts is a material with lower hardness than the substrate, in order to improve the fracture toughness of the tool surface (can be increased by more than 10%), which can reduce the chipping and breaking of the tool and expand the range of tool applications. 　　Diamond engraving knife tool as one of the components of super hard material, generally in the production process will be added to the tool with a coating, plus the coating of the tool life longer, the tool is also more wear-resistant. Today gives you the diamond engraving knife and other tools hardness measurement method and tool material. I hope it can help you.

What are the classifications of diamond tools? What are the application areas?

Diamond tools as a common high-speed cutting tools, with high hardness, thermal conductivity and good wear resistance, and can obtain high machining accuracy and efficiency and other advantages are widely used in various industries, but some people on the main material of diamond tools, the corresponding field is still not particularly clear, today Hua Ling super hard combined with their own decades of diamond tool making experience to talk to you about the diamond tools of those things things~ Application fields of diamond tools Diamond tools are mainly divided into three categories: single crystal (SPDT) diamond tools, polycrystalline (PCD) diamond tools and chemical vapor deposition (CVD) diamond tools. 1、Single crystal (SPDT) diamond tools Single crystal (SPDT) diamond tools are mainly made of large grain single crystal diamond (quality greater than 0.1g, minimum diameter length not less than 3mm), mainly used in precision CNC turning and mechanical processing with high requirements for surface roughness, geometric accuracy and dimensional accuracy. Monocrystalline diamond is mainly divided into two types: natural monocrystalline diamond and synthetic monocrystalline diamond. Among them, natural monocrystalline diamond is the most wear-resistant material in diamond, the radius of blunt circle of cutting edge after fine grinding can be as small as 0.008～0.005μm. but natural monocrystalline diamond is more brittle, its crystal exists anisotropy, different crystal surface or the same crystal surface in different directions of the crystal hardness is different, so in grinding and use must choose the appropriate direction. In addition, due to the limited resources of natural single crystal diamond, the price is expensive natural single crystal diamond tools are mainly used for ultra-precision cutting of certain non-ferrous metals or the making of gold jewelry. And synthetic single crystal diamond has good consistency in size, shape and performance, and due to the increasing maturity of high temperature and high pressure technology, a certain size of single crystal diamond can be synthesized, so when processing high wear-resistant laminated wood, its performance is better than PCD diamond and will not cause premature blunting of the cutting edge. 2、Poly-crystalline diamond (PCD) tools Polycrystalline diamond (PCD) is a polycrystalline material made of polycrystalline diamond single crystal powder and cobalt and other metal bond at high temperature (about 1800 ℃) and high pressure (5 ~ 6 MPa) conditions. Although its hardness is slightly lower than that of single-crystal diamond, it is an isotropic aggregate of randomly oriented diamond grains. When used as a cutting tool, it can be ground in any direction. In addition, it does not require the selection of the best solution surface as the front cutting surface as in the case of natural diamond. When cutting, the cutting edge is insensitive to accidental damage and has high wear resistance. It can keep sharp cutting edge for a long time, and high cutting speed and large back cutting (depth of cut) can be used during machining, and its service life is generally 10~500 times that of tungsten carbide based carbide tools. 3、Chemical vapor deposition (CVD) tools CVD diamond is a high wear resistance pure diamond material without bonding agent, prepared at low pressure (<0.1MPa).CVD diamond mainly has two forms: CVD thin film coating (CD) and CVD thick film (TFD).CVD thin film coating is deposited on carbide substrate (commonly used K-type alloy) by CVD (chemical vapor deposition) process, the thickness is about 10~30 μm, which is composed of thin film-like polycrystalline diamond. Because the substrate is easy to make complex shapes, it is suitable for tools with complex geometry, such as taps, drills, end mills and indexable inserts with chip breakers.CVD thin film coated tools are mainly used for high-speed precision machining of non-ferrous and non-metallic materials, and the tool life is nearly ten or even tens of times longer than that of uncoated carbide tools. However, CVD thin film coated tools are not suitable for machining composite materials such as metals because the hard particles in the composite material will wear through a layer of coating on the tool surface in a very short period of time. Although the price of CVD film coated tools is lower than that of similar PCD tools, the low bond between the diamond film and the base material limits its wide application.
