ASTM A283 Grade C is a low-carbon steel plate under the ASTM A283/A283M standard, valued for its moderate tensile strength of 55-75 ksi (380-515 MPa) and excellent weldability, making it ideal for structural applications and pressure vessels. The Indian equivalent is IS 2062 Grade E250, which offers comparable mechanical properties and chemical composition for general structural purposes.
As a leading Chinese manufacturer and exporter, Gangsteel produces high-quality sa 283 grade c steel plate within our asme sa 283/sa 283m range, ensuring compliance with ASTM and Indian standards for global projects.
ASTM A283 Grade C is a low and intermediate tensile strength carbon steel plate used in structural applications like buildings, bridges, and tanks, where moderate strength and good formability are essential.
Its Indian equivalent, IS 2062 Grade E250, is specified under the Indian Standard for hot-rolled structural steel, offering similar strength and weldability. Gangsteel's sa 283 grade c steel plate is manufactured to match these properties, complementing other grades like sa 283 grade a steel plate, sa 283 grade b steel plate, and sa 283 grade d steel plate for versatile structural applications.

Gangsteel's sa 283 grade c steel plate adheres to these compositions, ensuring seamless substitution with IS 2062 Grade E250.
ASTM A283 Grade C requires a minimum yield strength of 30 ksi (205 MPa) and tensile strength of 55-75 ksi (380-515 MPa), with excellent ductility for forming. IS 2062 Grade E250 offers a slightly higher yield of 250 MPa (36 ksi) and tensile strength of 360-470 MPa, suitable for similar structural applications. Both standards mandate tensile testing per ASTM A370 or equivalent IS methods. Gangsteel's asme sa 283/sa 283m plates, including sa 283 grade a steel plate, sa 283 grade b steel plate, and sa 283 grade d steel plate, meet these requirements through rigorous quality control.
ASTM A283 Grade C and IS 2062 Grade E250 are used in structural components like beams, columns, and pressure vessels, offering excellent weldability and moderate corrosion resistance. Their close equivalence allows interchangeability in most structural projects, particularly in India, where IS 2062 is widely specified. Gangsteel's sa 283 grade c steel plate is tailored for these applications, supported by certifications for global compliance.
