10.Mechanical properties of large diameter rectangular steel tubes

The mechanical properties of large-diameter steel pipes are important indicators to ensure their ultimate performance (mechanical properties), which depend on the chemical composition and heat treatment system of the pipes. So based on different usage requirements, the mechanical properties of large diameter spiral steel pipes are specifically introduced from the aspects of tensile strength, yield point, and elongation.

1. Tensile strength

The maximum force (Fb) that the specimen bears during the tensile process at break, obtained from the original cross-sectional area (So) of the specimen（ σ）， Called tensile strength（ σ b) , in N/mm2 (MPa). It represents the maximum resistance of metal materials to failure under tensile force.

2. yield point

The stress at which a metal material with yield phenomenon can continue to elongate without increasing (maintaining a constant) force during the tensile process is called the yield point. If the force decreases, the upper and lower yield points should be distinguished. The unit of yield point is N/mm2 (MPa).

3. Elongation after fracture

In the Tensile testing, the percentage of the increased length of the gauge length and the original gauge length after the sample is pulled off is called the elongation. with σ Represented in%.
