ASME SA283 grades (A, B, C, and D) is essential for cost-effective sourcing, compliance with global standards, and ensuring performance in applications like bridges, buildings, and low-pressure tanks. ASME SA283, under the asme sa 283/sa 283m standard, includes four grades—Grade A, Grade B, Grade C, and Grade D—with increasing tensile strength for welded structures.
At Gangsteel, a leading supplier from China, we produce high-quality plates like sa 283 grade a steel plate, sa 283 grade b steel plate, sa 283 grade c steel plate, and sa 283 grade d steel plate. This guide details equivalent materials for each grade, focusing on chemical composition, mechanical properties, and applications to help you choose the right steel. Equivalents align with standards like EN, JIS, and GB, ensuring compatibility for global projects.
ASME SA283 Grade A is a low-carbon steel with tensile strength of 45-60 ksi (310-415 MPa) and yield strength of 24 ksi (165 MPa) min, ideal for low-strength structural applications like simple buildings or storage tanks. Its primary equivalent is ASTM A283 Grade A, identical under ASTM A283/A283M. Equivalents are chosen for similar low-carbon composition and weldability, per asme sa283 grade a structural steel specifications.
Key Equivalents:
These equivalents suit low-load applications, ensuring easy fabrication.
ASME SA283 Grade B offers slightly higher strength with tensile 50-65 ksi (345-450 MPa) and yield 27 ksi (185 MPa) min, suitable for moderate-load structures like industrial frameworks. Its primary equivalent is ASTM A283 Grade B. Equivalents align with asme sa283 grade b mechanical properties guide for medium-strength needs.
Key Equivalents:
These support moderate-pressure designs with good weldability.
ASME SA283 Grade C provides higher strength with tensile 55-75 ksi (380-515 MPa) and yield 30 ksi (205 MPa) min, ideal for structural and low-pressure vessel applications like industrial tanks. Its primary equivalent is ASTM A283 Grade C, per asme sa283 grade c structural plate specifications.
Key Equivalents:
These equivalents are suited for moderate to high loads.
ASME SA283 Grade D offers the highest strength in the series, with tensile 60-80 ksi (415-550 MPa) and yield 33 ksi (230 MPa) min, perfect for heavy-duty structural applications like bridges or tanks. Its primary equivalent is ASTM A283 Grade D, per asme sa283 grade d yield strength specifications.
Key Equivalents:
These equivalents support demanding structural designs.
All SA283 grades have low carbon (0.24-0.27% max) and manganese (0.90 max) for weldability, with phosphorus (0.035 max) and sulfur (0.040 max) controlled to prevent brittleness. Grade D includes silicon (0.40 max) for enhanced properties. Equivalents like S235JR (C: 0.17 max, Mn: 1.40 max) and SS400 (C: not specified, Mn: 1.40 max) have slightly lower carbon but similar impurities.
