Chemical Composition of ASTM A36 Carbon H Beams
The controlled chemical composition of ASTM A36 H Beams ensures excellent weldability and stable fabrication behavior.
| Steel Grade | Application | Carbon (%) | Manganese (%) | Phosphorus (%) | Sulfur (%) | Silicon (%) |
|---|---|---|---|---|---|---|
| A36 | Steel sections | ≤ 0.26 | ** | ≤ 0.04 | ≤ 0.05 | ≤ 0.40 |
Low carbon content minimizes cracking risk during welding and allows easier forming and machining.
Mechanical Properties of A36 Structural H Beams
ASTM A36 H Beams provide balanced mechanical performance for light to medium structural applications.
| Steel Grade | Style | Tensile Strength | Yield Strength | Elongation (200 mm) | Elongation (50 mm) |
|---|---|---|---|---|---|
| A36 | Steel sections | 400 – 550 MPa | ≥ 250 MPa | ≥ 20% | ≥ 21% |
These properties make A36 suitable for structures where ductility and ease of processing are more critical than high-strength performance.
Typical Applications of ASTM A36 Structural H Beams

What is A36 grade steel equivalent to?
The ASTM A36 plate is equivalent to grades like ASTM A283C, JIS G3101 SS400, JIS G3106 SM400A, EN10025-2 S235JR, DIN17100 ST37-2, and FE360B.
What does A36 stand for?
A36 is designated by its mechanical properties instead of its chemical properties. In the American Society for Testing Materials (ASTM) system, the A stands for ferrous metal, while the 36 refers to its minimum yield strength of 36,000 PSI.
Is A36 high strength steel?
A36 steel in plates, bars, and shapes with a thickness of less than 8 inches (203 millimeters) has a minimum yield strength of 36 ksi (250 MPa) and ultimate tensile strength of 58–80 ksi (400–550 MPa).
Does A36 steel rust easily?
The material can be easily machined, making it suitable for manufacturing processes. Corrosion Resistance: While A36 steel has some resistance to corrosion, it is often coated or painted to enhance its durability in harsh environments.
What makes A36 steel so popular?
This steel plate is known for its high strength, formability, and weldability. It's also an excellent magnetic field conductor. Together, these benefits make A36 one of the most-used grades of carbon steel. The American Society for Testing and Materials (ASTM) designated it A36.
Is A36 good for bending?
ASTM A36 is the most commonly used mild and hot-rolled steel. It has excellent welding properties and is suitable for grinding, punching, tapping, drilling and machining processes. Yield strength of ASTM A36 is less than that of cold roll C1018, thus enabling ASTM A36 to bend more readily than C1018.
