ASTM A633 Grade D/A633 Gr.D structural steel plates are used for their higher strength and atmospheric corrosion resistance. A633 Gr.D steel can be considered to be microalloyed steel and are designed for mechanical rather than compositional specs. ASTM A633 Grade D/A633 Gr.D structural steel plates are used in welded, bolted, or riveted structures, above -45°C (-50°F) in which its strength and durability is required.
