Mechanical properties are one of the important properties of construction steel, so what are the mechanical properties? The main properties of steel include mechanical properties and process properties. Among them, mechanical properties are the most important performance of steel, including tensile properties, impact properties, fatigue properties, etc. Process properties represent the behavior of steel during various processing processes, including bending properties and welding properties, etc.
01. Tensile propertiesThe indicators of tensile properties of construction steel include yield strength, tensile strength and elongation. Yield strength is the basis for determining the strength of steel in structural design. The ratio of tensile strength to yield strength (strength-yield ratio) is a parameter to evaluate the reliability of steel. The greater the strength-to-yield ratio, the greater the reliability and safety of the steel when the force exceeds the yield point, but the greater the strength-to-yield ratio, the lower the utilization rate of steel strength and waste materials. The property that steel can withstand permanent deformation before being damaged by force is called plasticity. In engineering applications, the plastic index of steel is usually expressed by elongation. Elongation is the ability of steel to withstand permanent deformation when fracture occurs. The greater the elongation, the greater the plasticity of the steel. The percentage
