Introduction

High quality carbon structural steel hot rolled steel plate and steel strip (GB/T3275-1991)is a special material for the manufacture of automobiles, mainly used for the manufacture of various parts and components of automobiles, such as the fuselage, brake tank and other parts of the car body.

Characteristics of High Quality Carbon Structural Steel Hot Rolled Steel Plate

High quality carbon structural steel hot rolled steel plate has excellent mechanical properties and good formability, which makes it ideal for car manufacturing and car components. The following are the outstanding characteristics of this material:

1. High strength: The tensile strength of high quality carbon structural steel hot rolled steel plate is generally above 540MPa, and it can still maintain a certain degree of strength under more stringent manufacturing and processing conditions.

2. Good ductility: During the working process, this material has a good elongation and a certain degree of plasticity and can be processed at low temperatures.

3, wear resistance: High quality carbon structural steel hot rolled steel plate is wear-resistant and durable, and has good corrosion resistance and high temperature resistance.

4, low cost: Compared with other similar materials, its price is relatively low, and its production process is relatively simple, which helps reduce the cost of vehicle manufacturing.

Application of High Quality Carbon Structural Steel Hot Rolled Steel Plate

High quality carbon structural steel hot rolled steel plate is widely used in the automobile industry due to its excellent mechanical properties, good formability, wear resistance and corrosion resistance. This material is mainly used for the manufacture of various automobile components, such as various parts of car body, brake tank and other parts.

Conclusion

In summary, high quality carbon structural steel hot rolled steel plate has excellent mechanical properties and good formability, which have brought many advantages to the automobile industry. This material has widely used in manufacturing automobile parts, and its excellent characteristics help reduce the cost of automobile manufacturing.

High-quality carbon structural steels (GB/T3275-1991) are used for automobile manufacturing hot-rolled steel plate and steel strip. These steels are manufactured by conventional oxygen steelmaking process and hydrocarbon re-carburizing process. Therein, the main chemical composition of high-quality carbon structural steels is C (carbon content is 0.10-0.20%) and Mn (manganese content is 0.30-1.00%). GB/T3275-1991 stipulates the requirements for quality and performance of hot-rolled steels for automobiles, as well as the dimensional tolerance, shape and surface quality and mechanical properties.

High-quality carbon structural steels is generally characterized by good workability, toughness and plasticity, medium surface finish and moderate strength. This kind of steel has excellent intergranular corrosion resistance and stress corrosion resistance, and is widely used for automobile parts. The steel can guarantee that automobile parts have satisfactory high strength requirements, durability and good weldability.

It is worth noting that high-quality carbon structural steels should not be exposed to the atmosphere for too long, because it is sensitive to the harmful gas in the atmosphere and the metal structure is prone to corrosion. Therefore, the products should be taken care of and used carefully. Besides, during storage, they should be placed in a dry environment and kept away from moisture.
