One of the defining characteristics of high carbon steel is that it can be heat treated to produce a wide range of properties. For example, it can be quenched and tempered to achieve high strength, or it can be annealed to make it more malleable and easier to work with.
High carbon steel is often used to make tools and machinery components, as well as for constructing buildings and other structures. It is also used in the production of springs, knives, and other cutting instruments.
However, high carbon steel is more brittle than low carbon steel and is prone to cracking and breaking if not handled properly. It is also more difficult to weld and requires special techniques to join it effectively.
