Weldable 4130 Alloy Steel Round Tubes
 |
Also known as chrome-moly steel, these 4130 alloy steel round tubes have low carbon content for good weldability. They’re often used for roll cages and frames. To increase their wear resistance, you can harden them with heat treating.

Multipurpose 4140 Alloy Steel Round Tubes
 |
Also known as chrome-moly steel, these alloy steel tubes resist fracturing from repeated stress. They’re used for a wide range of parts, including cylinders, rollers, and frames. For added wear resistance, they can be surface hardened with heat treating.
Note: Tubes may be made from either 4140 or 4142 alloy steel. They are interchangeable in most applications.

Weldable 4130 Alloy Steel Rectangular Tubes
 |
Made from 4130 alloy steel, also known as chrome-moly steel, these tubes have low carbon content for good weldability. They’re often used for building frames and supports, since their flat sides make them easier to bolt than round tubes. To increase their wear resistance, you can harden them with heat treating.
