Carbon structural steel (GB/T 700 - 1988)
Carbon structural steel is a kind of steel which is often used in construction. It has a high carbon content, good toughness, and is widely used in the manufacture of various engineering components. As the name suggests, it is a type of steel typically used in the construction of structures. The carbon content is relatively high, which results in excellent strength and toughness, making it an ideal choice for a wide variety of applications.
Carbon structural steel belongs to the category of alloy steels, which are composed of a minimum of two elements to attain special alloying characteristics and improve the properties of the steel. The main elements found in carbon structural steel are iron and carbon. Additionally, other elements such as manganese, phosphorus, and sulfur may be added. The chemical composition of the steel plays a pivotal role in determining its properties, such as its strength, ductility, toughness, and formability.
Carbon structural steel produced to the Chinese GB/T 700 - 1988 standard has a carbon content ranging from 0.15% to 0.25% and it is typically alloyed with manganese, phosphorus, and sulfur to optimize its machinability. The steel is manufactured with many different chemical compositions and mechanical properties, so it is important to understand the precise requirements of the application before selecting a suitable grade.
Carbon structural steel has a wide range of uses in structural applications. It is used in the construction of buildings, bridges, machines, and other structures. It is also used in the manufacturing of tools, dies, and fasteners. Additionally, carbon structural steel is often used to produce springs and metal wire.
Carbon structural steel is an excellent choice for applications that require high strength and good toughness. It is also suitable for applications requiring good weldability and formability. Its relatively low cost make it a popular choice for metal fabrication and manufacturing.
Carbon structural steel must be adequately cared for to ensure its longevity. It should always be stored in dry, well-ventilated areas, and away from corrosive atmospheres. Periodic painting or other protective treatments are also recommended for long-term storage.
In summary, carbon structural steel is a versatile and cost effective steel used in a wide range of applications, including buildings, bridges, machinery, tools, and fasteners. It is known for its excellent strength, ductility, and formability and can be easily welded. Carbon structural steel must be appropriately cared for to ensure its longevity and desirable properties. The Chinese GB/T 700 - 1988 standard is commonly used for the production of standard grades of carbon structural steel.
