Steel express hardness
網頁The mechanical properties are sensitive to the content of carbon, which is normally less than 1.0 wt%. Hardness of Carbon Steel Brinell hardness of low-carbon steel is approximately 120 MPa. In materials science, hardness is the ability to withstand surface indentation ( localized plastic deformation) and scratching. 網頁Steels are iron–carbon alloys that may contain appreciable concentrations of other alloying elements. The percentage of carbon determines the type of the ferrous alloy: iron, steel or cast iron. Cast irons have become an engineering material with a wide range of applications and are used in pipes, machines and automotive industry parts.

網頁In materials engineering, cast irons are a class of ferrous alloys with carbon contents above 2.14 wt%. Typically, cast irons contain from 2.14 wt% to 4.0 wt% carbon and anywhere from 0.5 wt% to 3 wt% of silicon. Iron alloys with lower carbon content are known as steel. The difference is that cast irons can take advantage of eutectic ... 網頁What is Hardness of Steels – Definition. Hardness of Steels. High-carbon steel has approximately 0.60 to 1.00% carbon content. Hardness is higher than the other grades but ductility decreases. Brinell hardness of high-carbon steel is approximately 200 MPa. In the figure, there is the iron–iron carbide (Fe–Fe3C) phase diagram.
