COMPARISON to EQUIVALENT and ALTERNATIVE GRADES
A283 Grade C vs. A36 Steel
Both A283 Grade C and A36 steel have similar chemical compositions, with carbon content ranging from 0.18% to 0.27%, manganese content ranging from 0.60% to 0.90%, and small amounts of other elements. The main difference between these two grades is their tensile strength, where A283 Grade C has a minimum tensile strength of 55,000 psi (380 MPa), while A36 steel has a minimum tensile strength of 58,000-80,000 psi (400-550 MPa). A283 Grade C is typically used for general structural purposes, whereas A36 is used in a wider range of applications, including construction of buildings and bridges.
A283 Grade C vs. A572 Grade 50 Steel
A572 Grade 50 is a high-strength, low-alloy steel plate used in structural applications such as bridges and buildings. A572 Grade 50 has a higher tensile strength than A283 Grade C, with a minimum yield strength of 50,000 psi (345 MPa) and a minimum tensile strength of 65,000 psi (450 MPa). A572 Grade 50 also contains alloying elements such as vanadium and columbium to enhance its properties further. A283 Grade C is considered a lower-strength carbon steel in comparison, suitable for less demanding applications.
A283 Grade C vs. A516 Grade 70 Steel
A516 Grade 70 is a pressure vessel-quality, carbon steel plate used for moderate and lower-temperature service in pressure vessels. It has a higher tensile strength and yield strength compared to A283 Grade C, with a minimum tensile strength of 70,000 psi (485 MPa) and a minimum yield strength of 38,000 psi (260 MPa). A516 Grade 70 is primarily used in applications where elevated temperatures and pressure are involved, such as in the petrochemical and oil and gas industries. On the other hand, A283 Grade C is used for general structural applications and is not suitable for pressure vessel applications.
In summary, A283 Grade C steel is a low to intermediate tensile strength carbon steel plate used primarily for general structural purposes. While it shares some similarities with other grades like A36, it has distinct differences in terms of tensile strength, yield strength, and specific applications. When selecting a steel grade, it's essential to consider the specific requirements of the intended application to ensure the material's suitability.
