Metal fabrication experts use a wide range of machining and fabrication processes to produce custom parts and components for a variety of applications. Using cutting, grinding, and other fabrication techniques, these experts can improve the look, feel, and function of steel components. Several processes, such as heat treatments, enhance the strength and hardness of steel components. Metal fabrication experts also assemble multiple parts for products. Carbon steel is a common material for fabrication because it’s inexpensive and is composed largely of iron. This material contains as much as 3.8% carbon by weight. By increasing its carbon content, a steel component’s overall strength and hardness will increase.
