W-Beam Dimension & Weight Chart: American Wide Flange Beams

I. Introduction to the W-Series American Standard H-Beam

The American standard H-beam complies with the ASTM standard, with three main quality grades: A36, A572, and A992.

For instance, the A36 and A572 materials represent carbon structural steel, while A992 is a low alloy steel.

The American standard H-beam is a high-performance profile with an optimized cross-sectional area and a more reasonable strength-to-weight ratio, named after its H-shaped cross-section.

Due to its right-angled arrangement in all parts, the H-beam exhibits strong bending resistance, simple construction, cost-effectiveness, and lightweight structure, making it widely applicable.

II. Chemical Composition of the W-Series American Standard H-Beam

• C: 0.27~0.35;
• Si: 0.93~1.20;
• Ni: ≤0.029;
• Cu: ≤0.025;
• Mn: 0.80~1.10;
• S: ≤0.025;
• P: ≤0.026;
• Cr: 0.75~1.20;

III. Deoxidation and Alloying Performance of W-Series American Standard H-Beam Steel

The process involves releasing the molten steel when its temperature and composition meet the specifications for the steel type being refined. During steel tapping, caution must be taken to prevent slag from entering the ladle.

The additives used to adjust the temperature, composition, and deoxidation of the molten steel are added to the ladle or the stream of steel during tapping, also known as deoxidation alloying.

IV. Purpose of Normalizing the American Standard H-Beam:

1) To relieve the internal stress of the material

2) To adjust the hardness of the material (generally to increase) with a slight reduction in plasticity

This is to prepare for subsequent processing. It has a similar effect to annealing, but is aimed at improving efficiency and reducing cost.
