ASTM A283 Grade D Steel Plate

Overview of ASTM A283 Grade D Steel Plate

ASTM A283 Grade D is a specific carbon steel specification that covers four grades of low and intermediate tensile strength carbon steel plates for general structural applications. Grade D, in particular, offers a higher tensile strength compared to Grades A, B, and C, making it a reliable choice for structural components that require increased mechanical durability without the cost of high-alloy steels.

Shandong Tanglu Metal Material Co., Ltd. provides high-quality ASTM A283 Grade D steel plates, ensuring that each piece meets the stringent requirements of the American Society for Testing and Materials. Our Grade D plates are widely utilized in industrial environments, construction, and infrastructure projects where dependable structural integrity is paramount. We focus on delivering products with consistent quality and full material traceability for our global B2B clients.

Key Features and Fabrication Benefits

The primary feature of ASTM A283 Grade D is its balanced combination of tensile strength and excellent weldability. With a minimum yield strength of 33 ksi (230 MPa) and a tensile range of 60-80 ksi (415-550 MPa), it provides a robust framework for heavy-duty structures. Its low-to-medium carbon content ensures that it can be easily shaped, cut, and welded using standard industrial methods, including arc welding, MIG, and TIG processes.

From a fabrication perspective, ASTM A283 Grade D is highly versatile. It responds well to cold and hot forming, allowing for complex shaping into structural profiles like brackets, plates, and frames. The material’s uniform grain structure ensures precision during machining and drilling. For contractors and manufacturers, this translates to reduced processing times and higher efficiency in the workshop, while maintaining the structural safety standards required for long-term installations.

Main Applications of ASTM A283 Grade D Steel Plate

ASTM A283 Grade D steel plate is extensively used in the construction of storage tanks, bins, and low-pressure vessels. Its reliable strength makes it suitable for secondary structural members in buildings and bridges. In the manufacturing sector, it is a preferred material for fabricating machine bases, agricultural implements, and industrial support structures where a higher tensile strength than standard mild steel is required.

Furthermore, it is commonly applied in civil engineering projects, including transmission towers, highway guardrails, and railway infrastructure. Its durability under varied environmental conditions makes it a staple for large-scale industrial fabrication. Whether you are building a storage facility or a complex mechanical assembly, ASTM A283 Grade D provides the mechanical properties needed to ensure stability and performance.
