What Are The Requirements For Purchasing Steel Structure Materials

When purchasing steel structure materials for steel structure engineering, we must choose according to the requirements and needs of our own steel structure, so what requirements and conditions should be met when purchasing materials?
1. steel structure engineering in the purchase of good steel structure requirements for steel is many, first of all, need to understand the characteristics of steel structure building, must start from the steel structure material, master the steel in various stress states, different production processes and use conditions of the working performance, so as to select the applicable steel, not only make the steel structure engineering safe and reliable and meet the use requirements, but also can Z great possibility of saving steel and reducing costs.
2. First of all, there is high strength: the tensile strength and yield point of the steel are required to be relatively high. High yield point can reduce the cross-section of the component, thereby reducing weight, saving steel, reducing cost, high tensile strength, and can increase the safety reserve of steel structure building.
3. Then the plastic performance is good: it can make the steel structure structure have obvious deformation before failure, and can avoid brittle failure of the rabbit structure. Good plasticity can also adjust the peak stress of local components, so that the stress is distributed downward, and the well improves the ductility of components, thereby improving the seismic resistance of steel structure buildings. Good impact toughness can improve the resistance of the structure to dynamic loads and avoid cracks and brittle fractures.
4. Then the cold working performance is good: steel is often processed at room temperature, and good cold working performance can ensure that the steel structure components do not crack and brittle fracture during processing, and do not have a greater impact on strength, plasticity and toughness due to processing.
5. After Z, the weldability of steel is good: it means that under certain process and structural conditions, steel can obtain good performance after welding. Weldability is a measure of the hot working properties of steel. The weldability of steel structure engineering can be divided into weldability in construction and weldability in use, durability refers to the service life of steel structure building, affecting the service life of steel mainly because of poor corrosion resistance of steel, followed by the deterioration of mechanical properties of steel under long-term load, repeated load and dynamic load.
