Common Features
Compliance with international standards: A500 Grade B, C, and D steel pipes all comply with ASTM A500 standards, ensuring international recognition for quality and performance.
Versatility: These steel pipes are suitable for a variety of applications, including building structures, machinery manufacturing, etc.
Differences in chemical composition and mechanical properties
Grade Carbon content Tensile strength (MPa) Yield strength (MPa) Elongation (%) Cold bending performance
A500 GR.B Lower ≥400 ≥235 ≥21 Poor
A500 GR.C Medium ≥425 ≥315 ≥23 Better
A500 GR.D Higher ≥485 ≥345 ≥21 Better
A500 Grade B
Carbon content: relatively low, suitable for general structural applications1.
Mechanical properties: minimum tensile strength of 400 MPa, minimum yield strength of 235 MPa, and minimum elongation of 21%1.
Cold bending performance: poor, not suitable for projects that require bending1.
A500 Grade C
Carbon content: moderate, slightly higher than A500 GR.B1.
Mechanical properties: minimum tensile strength of 425 MPa, minimum yield strength of 315 MPa, minimum elongation of 23%1.
Cold bending performance: good, suitable for projects that require bending1.
A500 Grade D
Carbon content: the highest, suitable for projects that require high strength and durability1.
Mechanical properties: minimum tensile strength of 485 MPa, minimum yield strength of 345 MPa, minimum elongation of 21%1.
Cold bending performance: good, suitable for projects that require bending1.
Surface treatment
Galvanized treatment: A500 Grade B, C, D steel pipes are usually galvanized to improve their corrosion resistance and extend their service life23.
Applications
Building Structures: Due to their high strength and durability, A500 Grade B, C, D steel pipes are often used in building structures, such as frames, support columns, etc.13.
Machinery Manufacturing: These steel pipes are also widely used in machinery manufacturing, especially in components that require high strength and corrosion resistance1.
Conclusion
A500 Grade B, C, D Galvanized Steel Pipes have their own characteristics and are suitable for different application scenarios. Choosing the right grade depends on the performance requirements and budget constraints of the specific project. For general structural applications, A500 GR.B is an affordable choice; while for projects that require higher strength and corrosion resistance, A500 GR.C and A500 GR.D are more suitable.
