Use of steel structure processing materials
The development of social and economic strength makes the steel structure processing industry extremely important. Steel structure processing will be subjected to various forms during use, so steel is required to have good mechanical properties and processing properties to ensure the structure is safe and reliable. I believe everyone knows the process of processing steel components. But what kind of usability does the steel structure processing material have? Please see the analysis below.
There are many kinds of steels at present, and only a few of them meet the requirements of steel structure, such as l6Mn in low alloy steel and 20 manganese vanadium steel for high strength bolts.
So, what kind of usability does the need for steel-structured materials have?
The plasticity of steel generally refers to the property that after the stress exceeds the yield point, it has significant plastic deformation without breaking. The main indicators for measuring the plastic deformation ability of steel are elongation δ and reduction of area ψ.
2, cold bending performance
The cold bending property of steel is a measure of the resistance to cracking when steel is bent at room temperature to produce plastic deformation. The cold bending property of steel is the cold bending test to test the bending deformation performance of steel with a specified degree of bending.
The strength index of the steel is determined by the elastic limit σe, the yield limit σy, and the tensile limit σu. The design is based on the yield strength of the steel. The high yield strength can reduce the weight of the structure, save steel and reduce the cost.
This is the performance required for steel structure processing materials. In order to ensure the quality of steel structure processing, its material usability must be taken seriously.
