What are the material requirements for steel structure processing?
There are many types of steel, conforming toSteel structureThe variety of steel grades required by the company is not extensive. What usage requirements should the materials for steel structure processing meet?
Firstly, the plastic characteristics of stainless steel. The plastic characteristics of steel refer to its property of significant plastic deformation without fracturing when the stress exceeds the yield point. The indicators of the steel's plastic deformation capability are the elongation δ and the cross-sectional reduction ψ.
Next is the cold bending property of steel structures. The cold bending property of steel measures its resistance to cracking when it undergoes plastic deformation during bending processing at room temperature.
The cold bending property of steel is tested by a cold bending test, which examines the steel's ability to withstand bending deformation to a specified degree.
Thirdly, the strength of steel structures. The strength indicators of steel are the elastic limit σe, yield limit σy, and tensile limit σu. Steel structure design is based on the yield strength of steel, with a higher yield strength reducing the weight of the structure, lessening steel usage, and lowering construction costs.
To ensure the quality of steel structure processing, these are all aspects to be paid attention to.。
