Steel Hot Rolled Round Bar
A36 Hot Rolled - Round & Flat Bars
A36 Hot Rolled Round Bar
- Shape and Size: Round bars are cylindrical and are typically produced in diameters ranging from 1/8″ to several inches in size. They can also be found in larger custom diameters, depending on the application.
- Uses: A36 hot rolled round bars are commonly used in structural applications like beams, columns, and braces. They are also frequently used in the manufacturing of components that require machining or forging, such as shafts, axles, fasteners, and gears.
- Properties: Hot-rolled round bars made from A36 steel offer a good balance of strength and ductility. Their ability to be easily welded makes them ideal for structural and welding applications.
Key Characteristics of A36 Steel (Both Round & Flat Bars)
- Strength: A36 steel has a yield strength of 36,000 psi (pounds per square inch), making it strong enough for many structural applications.
- Weldability and Machinability: The steel is easily welded and machined, making it a go-to material for manufacturers and construction projects that require precision and structural integrity.
- Durability: While not as resistant to corrosion as some other steel grades (such as stainless steel), A36 steel is durable enough for most general-purpose applications, especially when treated with protective coatings.
In summary, A36 hot rolled round bars and flat bars are essential materials in a wide range of industries, from construction to manufacturing. Their versatility, strength, and ease of fabrication make them a go-to choice for many engineers and fabricators.
F1554 Grade 36 & Grade 55
F1554 Grade 36 and Grade 55 Hot Rolled Round Bars are both carbon steel products commonly used for anchor bolts and other structural components, defined by the ASTM F1554 standard. This standard covers the specifications for anchor bolts used in construction and industrial applications, ensuring that the material meets the strength and performance requirements needed for these critical applications. Both grades of F1554 round bars are produced through hot rolling, providing a good balance of strength, formability, and weldability.
F1554 Grade 36 Hot Rolled Round Bar
- Shape and Size: The F1554 Grade 36 round bar is cylindrical in shape and typically comes in diameters ranging from 1/2″ to several inches, with the size tailored to the needs of the project. It’s commonly available in lengths suited for anchor bolts, threaded rods, and other fabricated components.
- Uses: F1554 Grade 36 round bars are primarily used for anchor bolts, as the grade is specifically designed for anchor bolts and structural applications requiring moderate strength. These bars are often used in general construction, including securing structural components to concrete foundations and in applications where the steel is exposed to moderate stress and environmental conditions.
- Properties:
- Tensile Strength: Minimum 58,000 psi (400 MPa)
- Yield Strength: Minimum 36,000 psi (250 MPa)
- Weldability and Formability: This grade is known for good weldability and machinability, making it suitable for fabrication processes like cutting, welding, and threading.
- Durability: Grade 36 is suitable for use in general structural applications but is less resistant to corrosion compared to higher grades of steel.
F1554 Grade 55 Hot Rolled Round Bar
- Shape and Size: F1554 Grade 55 round bars are similar in shape, being cylindrical and typically available in a variety of diameters ranging from 1/2″ to several inches. They are made to be easily threaded and used in applications where higher strength is required compared to Grade 36.
- Uses: F1554 Grade 55 round bars are used in the same types of applications as Grade 36 but are more commonly found in high-strength anchor bolts, structural connections, and concrete anchoring systems that require higher tensile and yield strength. These bars are typically used in applications that will be subject to more demanding load conditions.
- Properties:
- Tensile Strength: Minimum 80,000 psi (550 MPa)
- Yield Strength: Minimum 55,000 psi (380 MPa)
- Weldability and Formability: F1554 Grade 55 bars offer excellent weldability and can be used in applications where precision machining and fabrication are required.
Durability: Offers better strength than Grade 36, making it more suitable for more demanding applications with higher load and stress requirements.
Key Differences Between F1554 Grade 36 and Grade 55 Round Bars
- Strength: Grade 55 has a higher yield strength and tensile strength compared to Grade 36, making it more suitable for applications involving higher loads or more demanding conditions.
- Use Cases: Grade 36 is generally used in less demanding applications such as securing non-critical components, while Grade 55 is used where greater strength is necessary, such as in seismic-resistant design or other heavy-duty structural applications.
- Fabrication: Both grades are designed for ease of welding, machining, and threading, with Grade 55 being used in projects requiring higher strength and more robust performance.
Summary of Properties:
Property | F1554 Grade 36 | F1554 Grade 55 |
|---|---|---|
Tensile Strength | 58,000 psi (400 MPa) | 80,000 psi (550 MPa) |
Yield Strength | 36,000 psi (250 MPa) | 55,000 psi (380 MPa) |
Applications | Anchor bolts, general structural use | High-strength anchor bolts, seismic applications |
Weldability | Good | Good |
Formability | Good | Good |
In summary, F1554 Grade 36 and F1554 Grade 55 hot-rolled round bars are critical materials for anchor bolts and structural components, with Grade 36 being more suitable for general-purpose applications and Grade 55 designed for heavy-duty, high-strength applications. Both are highly versatile and can be easily fabricated for a wide range of construction and industrial needs. Let me know if you need additional details!
