Tight-Tolerance Hardened Multipurpose 4140 Alloy Steel Bars

Also known as flat stock, the thickness on these bars is held to a tight tolerance. They are hardened for increased abrasion and impact resistance. Made from versatile alloy steel, also known as chrome-moly steel, these bars resist fracturing from repeated stress. They’re used for a wide range of parts, including molds and structural supports.

Note: Bars may be made from either 4140 or 4142 alloy steel. They are interchangeable in most applications.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Multipurpose 4140 Alloy Steel Bars

Also known as chrome-moly steel, this versatile alloy steel is used for a wide range of parts, such as molds and structural supports. It resists fracturing from repeated stress. You can also surface harden it with heat to add wear resistance.

If you don't see the size you're looking for, check out our Made-to-Order 4140 Alloy Steel Bars.

Note: Bars may be made from either 4140 or 4142 alloy steel. They are interchangeable in most applications.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Hardened Multipurpose 4140 Alloy Steel Bars

The surface of these bars is hardened to increase their resistance to impacts and abrasion. Also known as chrome-moly steel, which is used to create molds, structural supports, and other parts. It resists fracturing from repeated stress.

If you don't see the size you're looking for, check out our Made-to-Order Hardened 4140 Alloy Steel Bars.

Note: Bars may be made from either 4140 or 4142 alloy steel. They are interchangeable in most applications.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Multipurpose 4140 Alloy Steel Sheets

This versatile alloy steel is used for many parts, such as molds and structural supports. Also called chrome-moly steel, it resists fracturing from repeated stress. These ground sheets have undergone a process called decarburization, which removes residue created during manufacturing. As a result, they have a uniform surface that’s good for machining, heat treating for hardening and wear resistance, and finishing. The thickness is oversized for finishing to your exact requirements.

Note: Sheets may be made from either 4140 or 4142 alloy steel. They are interchangeable in most applications.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Made-to-Order 4140 Alloy Steel Bars

When an off-the-shelf size won't do, we'll get you the exact dimensions you need.

This versatile alloy steel is used for many parts, such as molds and structural supports. Also called chrome-moly steel, it resists fracturing from repeated stress. These ground bars have undergone a process called decarburization, which removes residue created during manufacturing. As a result, they have a uniform surface that’s good for machining, heat treating for hardening and wear resistance, and finishing. The thickness is oversized for finishing to your exact requirements.

Note: Bars may be made from either 4140 or 4142 alloy steel. They are interchangeable in most applications.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Weldable 4130 Alloy Steel Sheets

A low carbon content makes this 4130 alloy steel easy to weld. Also known as chrome-moly steel, it’s often used for pressure vessels and structural supports. It can be surface hardened with heat treating for added wear resistance.

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.

Hardened Weldable 4130 Alloy Steel Sheets

The surface of this 4130 alloy steel is hardened, so it resists impact and abrasion better than standard 4130 alloy steel. Also known as chrome-moly steel, it has a low carbon content for good weldability. 4130 alloy steel is often used for pressure vessels and structural supports.
