Show full description

Alloy Steel Hex Bar 4130 Hardened and Tempered

Our 4130 hardened and tempered alloy steel hex bar is engineered for high-stress applications requiring immediate structural integrity. These hexagonal bars are primarily used for manufacturing high-strength fasteners, hydraulic fittings, and aerospace connectors. The hardening and tempering process provides a superior balance of ductility and tensile strength compared to standard annealed versions. It is an essential material for the motorsports and defense industries where mechanical failure is not an option. Order your pre-treated 4130 hex bars from Onlinemetals.com to save time on post-production heat treating.
