ASTM A283 is a specification for low and intermediate tensile strength carbon steel plates used in general structural applications, such as buildings, bridges, and tanks. It covers grades A, B, C, and D, with Grade C being the most common due to its balanced strength and weldability. As a leading manufacturer and exporter, Gangsteel produces high-quality plates under asme sa 283/sa 283m, ensuring compliance with ASTM standards for global projects in construction and engineering.
ASTM A283 material is the ASTM-adopted version of low-carbon steel plates for structural and pressure vessel uses, equivalent to ASME SA 283. It specifies plates for low to moderate tensile strength, with no heat treatment required beyond rolling.
Gangsteel's asme sa 283/sa 283m plates are available in various grades, including 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, offering versatility for structural and vessel applications.

Gangsteel's plates meet these properties through advanced manufacturing, with optional impact testing for low-temperature use.
ASTM A283 material is widely used in structural components, pressure vessels, storage tanks, and general fabrication where moderate strength and good ductility are needed. It is not suitable for high-pressure or elevated-temperature service. Gangsteel's sa 283 grade c steel plate is popular for these applications, offering cost-effective solutions with excellent weldability.
