A283 Hexagonal Bar
ASTM A283 Hexagonal Bar is an economical carbon structural steel hexagonal bar, available in Grades A, B, C and D with hot-rolled and cold-finished options for general precision fabrication. It features well-balanced tensile strength and ductility, excellent weldability, machinability and cold workability for flexible on-site processing. The hexagonal cross-section is tailored for torque transmission and fastener production, with precise dimensional tolerance and uniform material quality for stable performance at normal temperature and pressure. Cost-effective and widely available, it’s a mainstream hexagonal bar for industrial and civil precision structural parts and hardware fasteners.
