ASTM A283 carbon steel plate

ASTM A283 is a standard specification for low and intermediate tensile strength carbon steel plates intended for structural applications. It covers four grades—A, B, C, and D—each offering different levels of mechanical properties suitable for general structural use in construction and engineering projects.

EN10025-2

DIN 17100 / DIN 17102

GB/T 700 / GB/T 1591

Standard and Composition

Under ASTM A283 / A283M, carbon steel plates are produced using open-hearth, basic oxygen, or electric furnace processes. Both heat and product analysis are conducted to ensure that the steel conforms to the required chemical composition limits for:

Carbon (C)

Manganese (Mn)

Phosphorus (P)

Sulfur (S)

Silicon (Si)

Copper (Cu)

In addition, all grades must meet specific mechanical performance requirements, including:

Tensile Strength

Yield Point

Elongation

These values vary by grade, providing options based on the intended use and design needs.

Workability and Applications

ASTM A283 steel plates are known for their excellent formability and weldability, making them easy to cut, machine, and fabricate using standard methods. The material supports all common welding techniques and provides reliable performance in both bolted and riveted structural connections.

Common Applications Include:

Building structures

Bridges

General fabrication

Storage tanks

Frame components

Because of its versatility and affordability, ASTM A283 is often considered interchangeable with other structural carbon steel grades such as ASTM A36, JIS SS400, and Chinese Q235.
