Multipurpose 4140 Alloy Steel Sheets and 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. These sheets and bars are manufactured to ASTM standards for quality and performance.

Note: Sheets and 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.
