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.

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.

Highly Fatigue-Resistant 4340 Alloy Steel Sheets
|
Made of 4340 alloy steel, these sheets hold up to high heat, hard impacts, and heavy wear thanks to high levels of nickel, chromium, and molybdenum. They’re often used to make machine tool bases and structural panels. For even more wear resistance, you can harden the surface with heat treating.

Highly Weldable Wear-Resistant 8620 Alloy Steel Sheets
|
Made of 8620 alloy steel, these sheets have low levels of carbon that make them easy to weld. High nickel, chromium, and molybdenum content make them resistant to wear. For even greater wear resistance, you can harden their surface with heat treating. They’re often used for wear plates and structural supports.

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.
