What factors affect carbon steel hardness?

Carbon steel hardness can be influenced by a number of different factors, including carbon contact, quantity and type of other alloy elements and specific processes used to create steel. Low -carbon steel, which contains 0.05 and 0.25% carbon, is usually the softest variety, although it can be cured by a process known as carbureization. Ultra -high carbon steel, which can consist of up to 2% carbon, is usually the most difficult type, although the final hardness of each product is also determined by different heat treatment processes. Taking processes can increase carbon steel hardness by a factor of about four, although subsequent temperature usually reduces hardness. Carbon steel

is an alloy that consists mainly of iron and carbon. Other elements may also be present, usually in very small quantities. There are several different definitions of what exactly represents carbon steel, although elements such as silicon and copper typically represent less than 0.6% of different alloys. Some carbon steel alloys may also haveup to 1.6% of elements such as manganese. Because there are a number of different alloys that are commonly referred to as carbon steel, each type of tendency has a different hardness.

The primary factor that affects the hardness of carbon steel is the amount of carbon present in the alloy. Low -carbon steels tend to be the softest, while ultra -high carbon steels can be quite hard and fragile. It is also possible to change the physical properties of carbon steel with different treatments, either to increase or reduce the hardness.

Although low carbon steel is relatively soft, the process known as carbureization can cause it to be harder. In fact, this heat treatment process causes an alloy to absorb another carbon from solid, liquid and gaseous sources such as coal and Odox carbocide. The carbon is usually absorbed only into the metal surface, resulting in the outer layer and a softer tow core.

carbon steels with highThe content tends to be very difficult, but the processes of frying can make them even more difficult. However, if the carbon steel alloy is too hard, it will usually be quite fragile. Some exceptionally hard alloys are in fact subjected to the processes of extinction and tempestation that can reduce carbon steel hardness and increase the ductility. Other processes, such as annealing, can also effectively increase the ductility and reduce the overall hardness of the carbon steel.
