Products Application
ASTM A283 Grade C steel plate is a medium-strength structural carbon steel, with a minimum yield strength of 205–250 MPa, a tensile strength range of 380–480 MPa, and an elongation of typically 20–26%.
Its chemical composition includes approximately 0.23–0.28% carbon, 0.60–1.20% manganese, and phosphorus and sulfur each not exceeding 0.05%, ensuring good toughness, weldability, and machinability.
This steel plate is widely used in bridges, workshops, warehouses, and high-rise building structures, where it can withstand moderate loads while maintaining structural stability and safety.
In manufacturing, A283 Grade C is suitable for the fabrication of frames, supports, and other structural components, and it is also used in the production of pressure vessels and storage tanks, meeting both pressure and temperature requirements.
For general fabrication and structural applications requiring moderate strength, this steel plate provides a reliable and economical solution, enhancing construction efficiency while reducing material costs.
