Carbon Structural Steel Cold Rolled Steel Strip (GB/T716-1991)

Introduction

Carbon structural cold rolled steel strips (GB/T716-1991) are the steel strips made of carbon structural and structural alloy steels. It is used to make structural tubing, car doors, and parts. GB/T716-1991 is an international standard for the production and manufacture of cold rolled steel strips, including carbon structural steel and structural alloy steel, for any scale and application.

Characteristic

Carbon structural cold rolled steel strips (GB/T716-1991) are high-density, high-strength, and reliable products. They have a uniform steel structure and are perfect for making steel products. The very small thermal deformation coefficient of this steel makes it ideal for cold strip engraving, saw cutting, and other manufacturing processes. The chemical composition of the carbon structural cold rolled steel (GB/T716-1991) is strictly controlled, and the roll edge has a very uniform and smooth profile, facilitating the welding and cutting of the steel strip during the manufacturing process. The carbon structural cold rolled steel strip (GB/T716-1991) is widely used for a variety of industrial applications, especially in construction and transportation.

Process

The manufacturing process of carbon structural cold rolled steel strip (GB/T716-1991) starts with the elimination of scale from the steel and then cold rolling for thickness accuracy and dimensional accuracy. In the cold rolling process, the steel is passed through a set of steel rollers that press out the steel into the desired shape. After cold rolling, the surface is descaled and then pickled, followed by oiling and tempering to form a protective coating, which improves the formability and corrosion resistance of the steel.

Applications

Carbon structural cold rolled steel strips (GB/T716-1991) are widely used in a variety of industries, including construction and transportation. These steel strips are mainly used in the production of structural tubing and components, such as automotive doors, structural steel shapes and beams, structural steel door frames and rails, and structural components for machinery. In addition, these steel strips can also be used for decorative purposes and in the production of parts for electronic products, such as relays, transformers and thermocouples.

Conclusion

In conclusion, carbon structural cold rolled steel strip (GB/T716-1991) is a wide range of quality steel products used for many applications in the industrial and transportation markets. It is produced in strict accordance with international standards, providing reliable and consistent products for different purposes. The high quality of this steel strip has made it an ideal choice for many industrial and transportation applications.

Carbon structural cold-rolled steel strip (GB/T716-1991) is a kind of cold-rolled steel strip made of plain carbon steels, mainly containing 0.06%～0.2%C and 0.1%～1.0% Mn. It is used for cold-formation and cold-welding. It is mainly used in the manufacture of cold-formed parts with complicated structure (including common pipes and profiles), deep drawing parts, etc. of construction, machinery and vehicle manufacturing.

Carbon structural cold-rolled steel strip (GB/T716-1991) is produced by cold-rolling hot-rolled plate, which is normalized and annealed before rolling to obtain uniform properties and texture. The texture of the steel strip produced is dominated by ferrite grains, and the steel has low carbon content, which can improve the flexibility of the steel strip and improve the bumps caused by cold-rolling, so as to ensure the appearance quality.

The cold-rolled carbon structural steel strip (GB/T716-1991) has a smooth surface, good mechanical properties, uniform grain size, and a good process formability. Its hardness is low, its tensile strength is greater than MS low carbon steel, and its elongation is also greater.

Carbon structural cold-rolled steel strip (GB/T716-1991) is widely used in the automotive industry, construction industry, mechanical industry, and other industries. Automobile manufacturing mainly used in mechanical parts, shell, and car exhaust system; construction mainly used for machinery parts and components; mechanical industry is mainly used for machine tools, cutting tools, measuring tools, molds and other products. With the continuous development of modern technology, cold-rolled steel strip has been widely used in these industries.
