A588 Steel Plate Brief Introduction

A588 steel plate is a high-strength, low-alloy structural steel material category with enhanced atmospheric corrosion resistance.A588M Gr(A, B, K) steel plate is alloyed with elements such as Cu, P, Cr, and Ni. As a result, it forms a protective layer on the surface of the metal base. This protective layer helps the steel achieve high atmospheric corrosion resistance. Therefore, engineers and builders widely use this type of steel in various weathering building structural components, especially in industrial atmospheric environments.
They also commonly apply it in bridge auxiliary structural components.

• Type: Weathering steel, low-alloy high-strength structural steel
• Standards: ASTM A588/A588M
• Delivery condition: Hot-rolled, controlled-rolled, normalized, etc. For thicknesses greater than 15 mm, Z-direction properties can also be customized according to customer requirements.
• Grade family: A588M GrA, A588M GrB, A588M GrK

A588M Gr(A, B, K) steel plate Chemical Composition

The following composition properties are ASTM specifications for these A588 grades.

Performance Properties

• High Strength: A588M GrB steel plates feature high yield strength and tensile strength, meeting the strength requirements for structural components.
• Excellent Weather Resistance: Through alloying design, the steel plate forms a protective layer on the surface of the metal substrate. This layer gives the steel plate high resistance to atmospheric corrosion. It is capable of withstanding oxidation, corrosion, and moisture erosion.
• Excellent Weldability: The steel plate has good weldability, facilitating welding connections during structural manufacturing processes.
• Good Processability: The steel plate is easy to cut, bend, and form, suitable for various processing requirements.
