There are many properties of square steel pipe, and it is because of the performance of these square steel pipes that we will use it as the main building material. The performance of square steel pipe mainly includes plasticity, fatigue, strength, hardness and impact toughness.
Square steel pipe
1. Plasticity refers to the ability of metal materials under load to produce plastic deformation without breaking. This is a very important parameter to measure the performance of a square steel pipe. This should not be overlooked during the purchase.
2. Fatigue refers to the square steel pipe which produces a certain degree of fatigue in the cyclic load, thereby affecting the service life of the components. When selecting a square steel pipe, a product with a suitable fatigue value is selected as required.
3.Strength refers to the ability of metal materials to withstand damage under static loading. This is also a matter that needs to be emphasized and noted in many projects. It can be divided into tensile strength, flexural strength, and telescopic strength depending on the mode of action of the load. And shear strength.
4. Hardness refers to the degree of hardness and hardness of metal materials. The commonly used methods for expressing the hardness of square steel pipe include Rockwell hardness, cloth hardness and dimensional hardness.
5. Impact performance is also an important indicator. It refers to the ability of a metal to resist impact damage under the action of an impact load.
