About Steel

Compare over 50 grades of steel and cast iron to find the right material for you—all with material certificates for traceability.

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.

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

Linear Shafts

Pair with linear bearings and shaft supports to create smooth, precise motion. These linear shafts are turned, ground, and polished to tight tolerances and hardened to resist wear.

Highly Wear-Resistant 440C Stainless Steel and Highly Wear-Resistant 420 Stainless Steel—Balancing strength, wear resistance, and corrosion resistance, these shafts can handle moisture and mild cleaning solutions.

Surface Smoothness—The lower the microinch value, the smoother the finish and the less friction it will cause on the bearing.
