What is SS321 stainless steel and why is it used for exhausts?

SS321 is a type of stainless steel that contains titanium. This addition makes it more resistant to high temperatures and corrosion, which is ideal for exhaust systems that experience extreme heat and harsh conditions.

What does '1.5D radius' mean for this bend?

The '1.5D radius' refers to the tightness of the bend. It means the center of the bend is 1.5 times the tube's diameter away from the tube's centerline, creating a smooth, gradual curve that helps exhaust gases flow more easily.

What is the advantage of mandrel bending?

Mandrel bending uses a supportive mandrel inside the tube during the bending process. This prevents the tube from collapsing or kinking, ensuring the diameter remains consistent throughout the bend for better exhaust flow.

About this part

Product Details

If you're fabricating a custom exhaust system, getting the bends just right is key to good flow and a clean install. This 45-degree elbow from Stainless Bros is made from SS321 stainless steel, which is a popular choice for exhaust components because it holds up well to high temperatures and resists corrosion.

This particular bend has a 1.5D radius, meaning the center of the bend is 1.5 times the diameter of the tubing away from the tube's centerline. This creates a smoother, less restrictive path for exhaust gases compared to tighter bends. It's a 16-gauge (.065 inch) wall thickness, which is a solid choice for most exhaust applications, offering a good balance of strength and workability. The mandrel bending process ensures the tube's diameter stays consistent throughout the bend, preventing kinks and maintaining optimal flow.
