ASTM-A36 is a US-standard carbon structural steel plate, and its implementation standard is ASTM's special technical conditions. ASTM is the abbreviation of the American Society of Testing and Materials, and A36 refers to the grade of this steel plate.

Chemical composition and alloy elements of A36 steel plate:
C: ≤0.25%; Si≤0.4%; Mn: 0.8-1.2%; P≤0.04%; S: ≤0.05%; Cu0.2%

Yield strength: ≥250. Tensile strength: 400-550. Elongation: ≥20.

1. Reheating
For excessively bent steel bars, they can be reheated to return them to their normal state, which can extend the service life of the steel bars.
2. Curve inversion method
Bend the excessively bent steel bars under normal conditions to reverse the original bending position, then buckle the steel bars to keep them from deforming, so that the original shape of the steel bars can be restored.
3. Core replacement method
Bend the core part (i.e. the center part of the steel bar) of the excessively bent steel bar, stretch the core part to flatten the curvature, and then move the original curvature to the core part, so that a new, non-bent steel bar can be obtained.
