Overview of ASTM A572 Grade 50 H Beam
ASTM A572 Grade 50 H beam is a high-strength, low-alloy structural steel with a minimum yield strength of 50 ksi (345 MPa) and a tensile strength of 65 ksi (450 MPa). Its design offers excellent bending and shear properties for structural applications.
ASTM A572 Grade 50 wide flange H beams
This steel is microalloyed with niobium and vanadium, and carbon content is ≤0.23%, ensuring good weldability. The H-beams are ideal for load-bearing structures such as buildings, bridges, and industrial plants.
ASTM A572 Grade 50 H-beams can be produced by hot rolling or normalizing processes, with thickness ranging from 8–300 mm to meet diverse project requirements.
Mechanical Properties and Dimensions
| Specification | Flange Width | Web Thickness | Unit Weight | Moment of Inertia (Iₓ) | Yield Strength (MPa) | Tensile Strength (MPa) |
|---|---|---|---|---|---|---|
| W16×36 | 6.99 in | 0.295 in | 36 lb/ft | 448 in⁴ | 345 | 450 |
Remark: The cross-sectional design optimizes material distribution, reducing weight while maintaining structural performance, making it suitable for large-span and heavy-load projects.
Applications of ASTM A572 Grade 50 H-Beam
ASTM A572 Grade 50 H-beams are widely used in buildings for columns and beams. Their high strength and low alloy composition ensure durability under heavy loads.
They are also applied in bridge construction, providing structural integrity while optimizing cost compared to similar grades such as ASTM A992.
Industrial plants, machinery manufacturing facilities, and large-span infrastructure projects benefit from A572 Grade 50 H-beams due to their excellent bending and shear performance.
Advantages of A572 Grade 50 Steel
- High strength-to-weight ratio, suitable for large-span projects
- Good weldability and formability for structural fabrication
- Cost-effective compared with ASTM A992, especially for projects with moderate toughness requirements
- Wide thickness range (8–300 mm) to meet diverse project demands

What is astm A572 grade 50 steel?
A572 Grade 50 steel plate is a HSLA steel that is considered a workhorse grade of steel. Because of its strength, less material is needed to meet application requirements than with other grades of steel.
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.
Is A572 steel corrosion resistant?
A572 steel is typically used in structural applications due to its high strength, ductility, weldability and corrosion resistance.
What is equivalent to astm A572 Grade 50 material?
Which steel grades equivalent to astm a572 grade 50 ? Xinsteel Industrial suggest you using steel grades EN 10025-2 S355JR,DIN 17100 St50-2,GB/T 1591 Q345B or Q355B. These steel materials are all low alloy high strength for structural buildings.
What is the difference between astm A572 Grade 50 and s355?
ASTM A572 Grade 50 is commonly used in heavier construction applications requiring higher strength, while S355JR is versatile and widely used in various structural applications across Europe.
