What requirements does the steel of steel structure fabrication?

Steel structure manufacturing is to grind the steel into the required form. Sometimes, the steel is found unqualified during the manufacturing process, and we will not use this material. Once used, it will affect the firmness of the overall structure. So, what kind of steel meets the requirements of steel structure fabrication?

1. High tensile strength and yield point

Tensile strength is an index to measure the bearing capacity of a structure. The yield point can reduce the dead weight of the structure, save steel and reduce the cost. Tensile strength refers to the measurement of the tensile strength of steel after large deformation, which directly reflects the advantages and disadvantages of the internal structural of steel structures. At the same time, when processing steel structures, the yield point can increase the safety of the structure.

2. High plasticity and toughness

It has good plasticity and toughness. Steel structure fabrication has sufficient strain capacity under static load and dynamic load, which can not only reduce the tendency of brittle damage of the structure, but also adjust the local stress through large plastic deformation, and has good resistance to repeated load.

3. Good process performance (cold working, hot working and welding)

Good processing properties should not only be easy to process into various forms of structures, but also not cause great adverse effects on the strength, plasticity and toughness of structures due to processing.

In addition, according to the specific working conditions of steel structure fabrication, steel is sometimes required to adapt to low temperature. Only in the process of material selection can the quality of high temperature and corrosive environment be guaranteed.
