ASTM A656 is a quenched and tempered high-strength low-alloy steel coil, available in Gr 50, 60, 70 and 80 with ultra-high yield strength graded upward. It features excellent cold formability, good weldability with simple pre-treatment, and outstanding impact toughness even at low temperatures. With customizable thickness, width and length, precise dimensional tolerance and uniform material structure, it’s a cost-effective high-performance material for heavy-duty load-bearing structural applications.
