Carbon steel bar is a widely used type of steel that is known for its high strength, durability, and versatility. It is made up of primarily carbon and iron, with other elements such as manganese, silicon, and sulfur added to enhance its properties. The carbon content of carbon steel bar can range from 0.05% to 2.0%, depending on the type of carbon steel used.
Carbon steel bar is available in various shapes and sizes, such as rectangular, round, square, and hexagonal. However, in this product overview, we will be focusing on the most commonly used shapes - rectangular and round.
Rectangular carbon steel bar, also known as low carbon steel bar, is a type of carbon steel that has a low carbon content. It is often used in structural applications due to its high strength and good ductility. The low carbon content also makes it easier to weld and form into different shapes. This type of carbon steel bar is commonly used in construction, engineering, and automotive industries.
Round carbon steel bar, also known as mild carbon steel bar, is a type of carbon steel that has a higher carbon content compared to rectangular carbon steel bar. This makes it stronger and more durable, making it suitable for heavy-duty applications such as manufacturing machinery, agricultural equipment, and oil rigs. Its excellent weldability also makes it a popular choice for welding and fabrication projects.
In addition to low carbon and mild carbon steel bar, there is also high carbon steel bar. This type of carbon steel has the highest carbon content, ranging from 0.6% to 0.99%. It is the strongest and hardest type of carbon steel, making it ideal for applications that require a high level of strength, such as making cutting tools, knives, and blades.
Overall, carbon steel bar is a versatile and widely used product that offers excellent strength, durability, and weldability. Its various forms and sizes make it suitable for a wide range of applications in different industries. With its excellent properties and affordable cost, carbon steel bar is a popular choice for many manufacturers and builders.
