Differences in performance and materials of American standard square tube A500GR.B, C, D
First, let's take a look at the common features of the American Standard Square Tube A500GR.B, C, and D. All three square tubes use the A500 standard published by the American Standards Association (ASTM), which means that they meet internationally recognized standards in terms of quality and performance. Whether you need it for building structures, mechanical manufacturing, or other fields, these three square tubes can meet your needs.
However, there are still some differences between the American Standard Square Tube A500GR.B, C, and D. First, from the perspective of chemical composition, the three are slightly different.
A500GR.B has a relatively low carbon content and is suitable for general structural applications. The slightly higher carbon content of A500GR.C gives it better tensile strength and corrosion resistance, and is suitable for projects that require higher strength and durability. A500GR.D further increases the carbon content, which can provide higher yield strength and is suitable for projects that withstand greater pressure and load.
Secondly, from the perspective of mechanical properties, there are also differences between the American Standard Square Tube A500GR.B, C, and D. The following are their mechanical property values:
A500GR.B: Low tensile strength of 400MPa, low yield strength of 235MPa, low elongation of 21%.
A500GR.C: Low tensile strength of 425MPa, low yield strength of 315MPa, low elongation of 23%.
A500GR.D: Low tensile strength of 485MPa, low yield strength of 345MPa, low elongation of 21%.
In addition, A500GR.C and A500GR.D are superior to A500GR.B in cold bending performance. If your project requires bending of square tubes, we recommend choosing A500GR.C or A500GR.D to ensure better cold bending performance.
