ASTM A992 / A572 Grade 50 H-Beam
In this article, we provide the latest mechanical and chemical specifications, applications, and sizing options for H-beams, helping you make informed purchasing decisions.
Mechanical Properties of ASTM A992 / A572 Grade 50 H-Beams
| Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation % (200 mm) | Elongation % (50 mm) |
|---|---|---|---|---|
| ASTM A992 | 345 | 450 | 18 | 21 |
| ASTM A572 Gr 50 | 345 | 450 | 18 | 21 |
Key Features:
High-strength low-alloy steel
Excellent weldability and ductility
Used for H-beams, wide-flange beams, channels, angles, and plates
Controlled yield-to-tensile strength ratio for structural reliability
Chemical Composition of ASTM A992 / A572 Grade 50 H-Beams
| Element | C % | Si % | Mn % | P % | S % | V % | Ni % | Cr % |
|---|---|---|---|---|---|---|---|---|
| ASTM A992 / A572 Gr 50 | 0.23 | 0.40 | 1.35 | 0.040 | 0.050 | 0.06 | 0.015 | 0.05 |
This composition provides excellent corrosion resistance, toughness, and high-temperature performance, making the beams suitable for bridges, buildings, heavy equipment, and industrial structures.
ASTM A992 vs A572 Grade 50 H-Beam Applications
ASTM A992 H-beams are primarily designed for wide-flange structures, large-scale buildings, and heavy-duty frameworks.
A572 Grade 50 H-beams offer similar strength and are ideal for bridges, structural supports, and mechanical equipment.
Applications include:
- High-rise building steel frames
- Bridge construction and supports
- Heavy machinery frames
- Industrial plant structures
- Channels, angles, and plates for structural reinforcement

Application
What is grade A992 steel?
ASTM A992 is currently the most available steel type for structural wide-flange beams. The industry's technical institute describes the standard thus: "ASTM A992 (Fy = 50 ksi, Fu = 65 ksi) is the preferred material specification for wide-flange shapes, having replaced ASTM A36 and A572 grade 50.
What is the difference between A992 and A572?
A992 is primarily available as structural shapes, not plates or bars, and is the standard for wide-flange beams in the U.S. Key Difference: A572 Gr 50 is a broader specification for various forms and general structural use, while A992 is tailored for wide-flange shapes in building construction with enhanced properties.
Is A992 the same as A36?
ASTM A992 outperforms A36 in structural strength, weld consistency, and seismic resilience-making it ideal for modern construction. Still, A36 remains a solid, cost-effective choice for lighter-duty and non-critical applications. Choose based on structural requirements, budget, and project design.
Is the ASTM A992 galvanized?
No. Steel beams are galvanized to ASTM A123. You would need to order galvanization from the steel supplier. ASTM A992 is just the standard for strength requirements and metallurgy of structural steel shape you receive.
Is A572 stronger than A36?
The higher presence of strengthening alloys, such as manganese and silicon, in A572 plate grades give the material greater strength as compared to A36. This higher strength allows A572 steel to bear more weight and withstand greater forces without breaking or failing, which is crucial in structural applications.
