Easy-to-Weld 4130 Alloy Steel Sheets and Bars

Yield Strength: 50,000 psi
Hardness: Rockwell B85 (Medium)
Heat Treatable: Yes
Max. Hardness After Heat Treatment: Rockwell C49
Fabrication: See table
Specifications Met: SAE AMS6350, SAE AMS6351

A low carbon content makes this 4130 alloy steel easy to weld. Also known as chrome-moly steel, it’s often used for pressure vessels and structural supports. It can be surface hardened with heat treating for added wear resistance. These sheets and bars have been manufactured to meet SAE standards for quality and performance.

Easy-to-Weld 4130 Alloy Steel Triangles

Yield Strength: 50,000 psi
Hardness: Rockwell B85 (Medium)
Heat Treatable: Yes
Max. Hardness After Heat Treatment: Rockwell C60
Fabrication: See table
Specifications Met: SAE AMS6350, SAE AMS6351

Weld these alloy steel triangles to strengthen joints in structural applications. They're also known as gussets. They have clipped corners that leave room for a weld bead, so you can make stronger welds. Made from 4130 alloy steel, also known as chrome-moly steel, these triangles have low carbon content for good weldability. To increase their wear resistance, you can harden them with heat treating. They have been manufactured to meet SAE standards for quality and performance.
