W Beam Dimensions and Weight Table: American Wide Flange Beams

I. Introduction to American Standard W Series H Beam

American standard H beam conforms to ASTM standard, with three main quality grades: A36, A572 and A992.

For example, materials A36 and A572 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 for its H-shaped cross-section.

Due to its right-angle arrangement in all parts, H beam features strong bending resistance, simple construction, economy and light structure, making it widely applicable.

II. American Standard W Series H Beam Chemical Composition

• 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 Alloy Performance of American Standard W Series H Beam Steel

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

Additives used to adjust the temperature, composition and deoxidation of molten steel are added to the ladle or steel stream during threading, also known as deoxidation alloy.

4. 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 aims to improve efficiency and reduce costs.
