What is the requirement of steel structure building?

Steel structures workshop will be subjected to a variety of interactions, so the steel used has excellent mechanical properties and production performance.

1. Ductility. To put it plainly, plastic deformation refers to the obvious plastic deformation without fracture after the ground stress exceeds the yield limit. The ductility of steel determines its deformation capacity.

2. Compressive strength. The compressive strength index value of steel is composed of ductility limit, strength limit and compressive strength limit. Generally, it is based on the yield strength of steel. High yield strength can alleviate the weight of the structure, save steel and reduce the project cost. The compressive strength refers to the ground stress that steel can bear before being destroyed, which can be used as the main parameter of steel compressive strength storage.

3. Durability. There are many elements that endanger steel durability, corrosion resistance and heat resistance are the most important 2 elements. If steel is corroded and corroded or becomes brittle under long-term high temperature, it will harm its safety performance. In order to improve the durability of steel, a series of protective measures must be adopted, such as hot-dip galvanized steel and maintenance of steel paint on time.

4. Welding performance of electric welding. Good steel must have excellent welding welding performance, everybody said welding welding performance is usually referred to in - welding methods under the standard of good butt weld, it can avoid weld metal materials are caused cracks and surrounding the original material, in addition, the impact toughness of welds and hot ductility performance hazard area.

5. Impact toughness. It refers to the ability of digestion and absorption of mechanical energy of mechanical equipment in the whole process of breaking steel under impact load effect. It can consider the impact load resistance effect of steel. The impact toughness index value of steel is generally obtained through the impact test of standard samples.

6, cold drawing performance. Is to consider the steel in normal temperature bending production processing caused by plastic deformation of crack resistance, according to the cold drawing test to test the steel to bear the bending level of bending deformation performance.
