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 and cracking in demanding exhaust applications.

What is a mandrel bend?

A mandrel bend is created using a flexible internal support (a mandrel) that follows the tubing through the bending process. This prevents the tube from collapsing or kinking, ensuring a smooth, consistent inner diameter throughout the bend for better exhaust flow.

What does '1.5D radius' mean?

The 'D' refers to the outer diameter of the tubing, which is 1.75 inches in this case. A 1.5D radius means the center of the bend is 1.5 times the tubing's outer diameter away from the tube's centerline. This results in a tighter, more compact bend compared to a larger radius.

About this part

Product Details

What you get here is a single 90-degree mandrel bend elbow from Stainless Bros, made from SS321 stainless steel with a 1.75-inch outer diameter and a 1.5D radius. This piece is designed for custom exhaust fabrication, allowing you to create smooth, tight bends without kinking the tubing. The 'no leg' designation means it's a clean 90-degree turn, ready for you to weld into your custom exhaust system.

The SS321 stainless steel is a good choice for exhaust components because it offers improved corrosion resistance and can handle the high temperatures found in exhaust systems. Mandrel bending ensures that the inside diameter of the tubing stays consistent through the bend, which helps maintain good exhaust flow compared to crush bends. This is important for keeping your engine running efficiently and sounding right.
