Differences between A36 material W16x77 W16x67 wide flange H-beam
Moment of inertia: The flange thickness and web thickness of W16x77 h-shaped iron beam are greater than those of W16x67, and the bending moment of inertia is increased by about 15%-20%.
Section modulus: The section modulus of W16x77 h-shaped steel beam is higher, which is suitable for larger spans and load requirements.
Chemical composition of A36 h type beam: carbon content ≤0.25%, manganese 0.8%-1.2%, silicon ≤0.4%, phosphorus ≤0.04%, sulfur ≤0.05%, copper content ≤0.2%, low carbon design ensures weldability.
Mechanical properties of A36 h type steel beam
Yield strength: ≥250MPa (36,000psi), meeting general structural load requirements.
Tensile strength: 400-550MPa, higher strength when thickness ≤20mm.
Elongation: ≥20%, excellent toughness, can adapt to cold bending, stamping and other processing.
