4130 Product Guide Product   | 4130 Alloy Steel Tolerance Guide product

Alloy Steel 4130 offers good strength, and weldability without compromising steel abrasion and impact resistance. Easy to machine and hot work as well as cold work in the annealed state, it becomes significantly more challenging once the steel is hardened. 4130 steel can also be easily welded. It is typically used in structural applications, including gears, fasteners, and some aircraft exterior.

 

We offer 4130 in round tube, seamless round tube, square tube, hex bar, cold drawn hex bar, cold finish hex bar, rectangle bar, normalized rectangle bar, round bar, sheet plate, annealed sheet plate, normalized sheet plate, and sample packs.
