Difference Between Tungsten Steel And Stainless Steel

Tungsten steel and stainless steel are common in the machining industry, but they are very different. This article will tell you the difference between tungsten steel and stainless steel, and the knowledge points corresponding to the difference between tungsten steel and steel.

Stainless Steel:

Iron and carbon alloy with carbon content<2.11% is called ordinary carbon steel, which is easily oxidized, rusted and formed holes when exposed to the air. Stainless steel is a kind of high alloy steel that can resist corrosion in air or chemical corrosive medium.

Because stainless steel contains chromium, it forms a very thin chromium film on the surface. This film separates the oxygen from the steel and plays a role in corrosion resistance. In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 12% chromium.

Tungsten Steel:
Tungsten steel is also called tungsten-titanium alloy or high-speed steel or tool steel. The hardness is Vickers 10K, second only to diamond. It refers to the sintered composite material composed of at least one metal carbide. Tungsten steel and cemented carbide have a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance. The advantages of tungsten steel mainly lie in its high hardness and wear resistance, and its high hardness even at 1000C. It can be called the second diamond. The grain size of carbide component (or phase) is usually between 0.2-10 microns.

The hardness of tungsten steel is generally in the range of 8.5-9.5. The hardness of tungsten steel is four times that of titanium and twice that of steel. So it is basically zero scratch. Tungsten steel is very popular with consumers. The hardness of this material is close to that of natural diamond, it is not easy to wear, its brightness is like a mirror, it never fades, and it can withstand mechanical impact.

Which is heavier with the same volume of tungsten steel and stainless steel?
Tungsten steel is heavy. Tungsten steel, also known as cemented carbide, has a density of 14.8, while stainless steel has a density of 7.9

Which is better, tungsten steel or stainless steel
Stainless steel is stainless steel and tungsten steel is tungsten steel. The two are not the same. Stainless steel is used to make products, while tungsten steel is used to make tools, tools and tooling. Tungsten steel blades, namely carbide blades, are used to cut metal materials.

According to the properties of materials, the properties of tungsten steel must be the best. As for the different uses, it is difficult to determine whether it is good or bad. But it is certain that tungsten steel has the best performance and the most expensive price, so you can choose the right one according to your own situation.

What is the hardness of tungsten steel and stainless steel respectively
Tungsten steel is different from high-speed steel. The hardness of tungsten steel is generally more than 90, while that of stainless steel is generally more than 40-50.
