What is SS321 stainless steel?

SS321 is a type of stainless steel that includes titanium. This addition helps prevent carbide precipitation at high temperatures, making it more resistant to corrosion in harsh exhaust environments.

What does 'mandrel bend' mean for an exhaust tube?

Mandrel bending uses a shaped internal support (a mandrel) to maintain the tube's original diameter and prevent it from collapsing or kinking during the bending process. This ensures smooth exhaust flow.

What is the radius of this elbow?

This elbow has a 1.5D radius. 'D' refers to the diameter of the tube, so the center of the bend is 1.5 times the tube's diameter away from the tube's edge.

About this part

Product Details

If you're building a custom exhaust system, you know how important it is to have the right bends. This 3-inch, 90-degree mandrel bend elbow from Stainless Bros is designed to help you achieve smooth transitions in your tubing.

Made from SS321 stainless steel, this elbow offers good resistance to high temperatures and corrosion, making it a solid choice for exhaust applications. The 1.5D radius means it has a tighter bend than a larger radius elbow, which can be useful when space is limited. The 16-gauge (0.065-inch) wall thickness provides a good balance of strength and weldability for fabrication projects. Mandrel bending ensures the tube maintains its shape and diameter through the bend, preventing kinks and improving exhaust flow.
