What is SS321 stainless steel?

SS321 is a type of stainless steel that includes titanium. This addition makes it more resistant to sensitization and corrosion, especially at high temperatures, which is why it's commonly used in exhaust systems.

What does '1D radius' mean for this bend?

A 1D radius means the center of the bend is one times the tubing's diameter away from the outer wall of the tube. This results in a tighter bend compared to larger radius bends.

Why is a mandrel bend important for exhaust fabrication?

Mandrel bending uses a solid internal mandrel to support the tube during the bending process. This prevents the tube from collapsing or kinking on the inside of the curve, maintaining a smooth, consistent inner diameter for better exhaust flow.

About this part

Product Details

Stainless Bros is known for providing well-built exhaust components, and this 1.625-inch 90-degree mandrel bend elbow is a prime example. If you're fabricating a custom exhaust system, this piece is designed to give you a smooth, consistent bend for optimal flow. It’s made from SS321 stainless steel, which is a popular choice for exhaust applications because it handles high temperatures well and resists corrosion.

This elbow features a 1-diameter (1D) radius, meaning the center of the bend is one times the tubing's diameter away from the tubing's outer wall. This tight radius is useful when you need to make a sharp turn in a tight space. The tubing itself is 16-gauge thick, or .065 inches, which offers a good balance of strength and workability for custom fabrication projects. Because it's a mandrel bend, the inside of the curve stays round and doesn't collapse, ensuring exhaust gases can move through without restriction.
