Hardened Easy-to-Weld 4130 Alloy Steel Sheets

Yield Strength: 80,000 psi
Hardness: Rockwell C21 (Hard)
Fabrication: See table
Specifications Met: ASTM A506, SAE AMS2301

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. These sheets have been manufactured to meet SAE and ASTM standards for quality and performance.

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

Easy-to-Weld 4130 Alloy Steel Rods

Yield Strength: Not Rated
Hardness: Rockwell C21 (Hard)
Fabrication: See table
Specifications Met: See table

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. These rods have been manufactured to ASTM and SAE standards for quality and performance.

Ultra-Strength Fatigue-Resistant 4330 Alloy Steel

Yield Strength: 185,000 psi
Hardness: Rockwell C23 (Hard)
Heat Treatable: Yes
Max. Hardness After Heat Treatment: Rockwell C46
Fabrication: Hot Rolled
Specifications Met: SAE AMS2301, SAE AMS6411

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 and discs are often used for gears, axles, and shafts. They have been manufactured to meet AMS standards for quality and performance.

Easy-to-Harden Wear-Resistant A355 Alloy Steel

Yield Strength: 85,000 psi
Hardness: Rockwell C23 (Hard)
Heat Treatable: Yes
Max. Hardness After Heat Treatment: Rockwell C67
Fabrication: See table
Specifications Met: See table

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. These rods have been manufactured to meet SAE standards for quality and performance.
