Products Description
A283 Grade B steel plate strictly conforms to the current ASTM A6/A6M specification, which defines the requirements for dimensions, permissible tolerances, surface quality, and mechanical properties. During production, A283 Grade B can be manufactured by one or more of the following processes: Open Hearth Furnace (OHF), Basic Oxygen Furnace (BOF), or Electric Furnace (EF), ensuring uniform chemical composition and stable mechanical performance.
The plates also undergo strict heat treatment and quality inspections to guarantee that yield strength, tensile strength, and elongation meet the standard requirements, while maintaining good weldability and workability.
The A283 steel plate series includes four grades: Grade A, Grade B, Grade C, and Grade D, all of which are structural carbon steel plates suitable for general engineering applications. Each grade varies in strength, elongation, and carbon content to meet different structural needs.
Among them, Grade B is a low to intermediate tensile strength steel plate with excellent weldability and machinability, making it suitable for building structures, bridges, storage tanks, workshops, and machinery.
This series of steel plates not only ensures safety and load-bearing capacity but also effectively reduces material costs, making it a commonly chosen, economical structural steel solution.

Products Application
ASTM A283 Grade B (A283GRB) steel plate is a low to intermediate tensile strength structural carbon steel, with a minimum yield strength of 205 MPa, a tensile strength range of 380–480 MPa, and an elongation of typically 20–26%.
The plate offers good toughness, plasticity, and weldability. Its chemical composition includes approximately 0.21–0.26% carbon, 0.60–1.20% manganese, and phosphorus and sulfur each not exceeding 0.05%, ensuring stable and reliable performance during fabrication and welding.
A283 Grade B steel plate is widely used in bridge construction, highway construction, workshops, warehouses, storage tanks, and other engineering projects. In bridge and highway applications, it can withstand substantial structural loads while maintaining excellent stability and safety.
For general engineering structures, this steel plate meets load-bearing requirements, enhances construction efficiency, and reduces material costs, making it a reliable and economical choice for structural steel in engineering projects.
