What is structural steel used for?

Structural steel is generally used for load-bearing purposes.
Engineering structural steel is a type of steel that is often used in various projects. We all know that structural steel is mainly used to manufacture engineering structures and mechanical structures. Structural steel mainly includes two categories: engineering structural steel and mechanical manufacturing structural steel. The performance requirements of these two types of structural steel are different. Engineering structural steel is mainly used to manufacture various engineering structures. What are the main applications of engineering structural steel? Let's take a look.
Engineering structural steel is commonly used in manufacturing bridges, ship hulls, oil wells or mine derricks, rails, various high-pressure vessels and pipelines, building steel structures, etc. Engineering structural steel is required to be able to withstand various loads. To achieve relatively high yield strength, engineering structural steel must also have good plastic toughness, so as to ensure the reliability of the engineering structure during use.
In addition, engineering structural steel is generally used outdoors, so the working environment of engineering structural steel is exposed to the atmosphere. The temperature in some places where engineering structural steel is used will be very low, so in these places it is required Use low-temperature toughness, and engineering structural steel is also required to be resistant to atmospheric corrosion.
Engineering structural steel generally includes carbon engineering structural steel and high-strength low alloy steel.
Carbon engineering structural steel belongs to non-alloy steel, and high-strength low-alloy steel belongs to low-alloy steel.
