With the development of social and economic strength, the steel structure processing industry is very important.Steel structure processing will be affected by various forms in the use process, so it is required that steel should have good mechanical properties and processing performance to ensure the safety and reliability of the structure.For Guiyang steel structure processing components of the process, I believe that we all understand.But what kind of usability should steel structure processing materials have?Please look at the analysis below.

At present, there are many kinds of steel, only a few of which meet the requirements of steel structure, such as l6Mn in low alloy steel, 20 manganese vanadium steel for high-strength bolts, etc.

So, what kind of usability does the steel structure processing material need?

1, plasticity

The plasticity of steel generally means that after the stress exceeds the yield point, it has obvious plastic deformation without fracture.The main indexes to measure 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 to measure the resistance of steel to crack when it is bent to produce plastic deformation under normal temperature.The cold bending performance of steel is to test the bending deformation performance of steel under specified bending degree by cold bending experiment.

3. strength

The strength index of steel is composed of elastic limit σ e, yield limit σ y, and tensile limit σ u. The design is based on the yield strength of steel. High yield strength can reduce the self weight of structure, save steel and reduce the cost.

This is the use performance of steel structure processing materials.If we want to guarantee the quality of steel structure processing, we must pay attention to its material usability.
