Corten B angle chemistry material analysis

ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates are structural quality carbon steel plates just as Corten B angle chemistry. ASTM A573 steel gardes are in three tensile strength ranges intended primarily for structural applications at atmospheric temperatures for which improved toughness is required.
