Weldable 4130 Alloy Steel Rods
 |
Made from 4130 alloy steel, also known as chrome-moly steel, these rods have low carbon content for good weldability. They’re often used to make gears and bushings. The surface of these rods is hardened to make them more resistant to wear and impacts. They’re also normalized, which is a heating process that relieves internal stress and helps prevent cracking during machining or additional hardening.

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.

Extreme-Strength Highly Fatigue-Resistant 4330 Alloy Steel Rods
 |
Made of a chromium-nickel-molybdenum alloy and strengthened with vanadium, this steel is the strongest alloy we offer. A vacuum arc remelting (VAR) process gives 4330 alloy steel excellent strength, hardness, and fatigue resistance. It also resists cracking from impact or compression. In addition to the VAR, this steel's been normalized—a form of heat treatment that helps yield consistent results if you want to machine or heat treat it further. More heat treatment will make the surface harder and more wear resistant. These rods are often used for gears, axles, and shafts.

Easy-Harden Wear-Resistant A355 Alloy Steel Rods
|
Also known as Nitriding 135, this steel can be hardened at lower temperatures than other heat-treatable alloys. Heat treating gives it a wear-resistant surface without making the interior brittle. It’s often used for gears, axles, and shafts.
