Application of Hot Rolled Hexagonal Steel and Octagonal Steel (GB 705-890)
Hot rolled hexagonal steel and octagonal steel (GB 705-890) are steels with different strength performance and mechanical properties. The two steel materials are mainly is mainly used in engineering structures, such as buildings, bridges, tunnels, etc., and in the manufacture of various mechanical components, since it has superior strength and good impact toughness.
Hexagonal steel and octagonal steel with GB 705-890 is a kind of structural carbon steel, which is a kind of non-alloy constructional steel that contains up to 0.25% of carbon content. It is divided into several types, such as low carbon steel, medium carbon steel and high carbon steel according to the carbon content. It exhibits better plasticity and toughness than other types of carbon steel. This type of steel is usually used in the production of parts with higher strength, such as bridges, buildings, etc.
Hexagonal steel and octagonal steel according to GB 705-890 are characterised by good hardenability and better weldability than other steels. Besides, they also show higher yield strength and overall fatigue strength, and higher resistance to shock loading. Moreover, they exhibit better durability than other carbon steels, as they are resistant to atmospheric corrosion. This feature makes it suitable for outdoor structures in harsh environment. Moreover, the surface of this type of steel has a high surface hardness, which can increase its wear resistance.
However, this type of steel still has some defects. They include relatively low toughness, which limits its application in some fields. Moreover, its low surface hardness makes it unsuitable for dealing with larger amount of load.
In summary, hot rolled hexagonal steel and octagonal steel with GB 705-890 have many advantages in steel structure engineering, such as good strength, weldability and durability. Besides, they can also be used in other fields, such as boats and ships, pressure vessels and hydraulic cylinders. Moreover, their advanced production technology greatly improves the quality of the steel, making them good choices for customers.
