Difference Between Tungsten Steel And Stainless Steel

DALIAN, China - March 26, 2023 - PRLog -- 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.
