What is a mandrel bend?

A mandrel bend is created using a flexible internal support (mandrel) that prevents the tubing from collapsing or kinking during the bending process. This maintains the tube's original diameter and shape, which is important for smooth exhaust flow.

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 suitable for high-heat exhaust applications.

What does 1D radius mean?

A 1D radius means the center of the bend is one times the tube's diameter away from the tube's edge. For a 3-inch tube, this results in a tighter, more compact bend compared to larger radii.

About this part

Product Details

This is a 3-inch diameter, 45-degree mandrel bend elbow from Stainless Bros, made from SS321 stainless steel with a 16-gauge wall thickness. It features a 1D radius, meaning the center of the bend is one times the tube diameter away from the tube's edge, creating a tighter curve. This type of component is essential for custom exhaust system fabrication, allowing you to route tubing around obstacles or create specific configurations.

The SS321 stainless steel construction offers good resistance to high temperatures and corrosion, making it a solid choice for exhaust applications where heat and exhaust gases are a concern. The 16-gauge (0.065-inch) wall thickness provides a good balance of strength and weldability for custom exhaust projects. Mandrel bending ensures that the tube maintains its diameter throughout the bend, which helps maintain smooth exhaust flow compared to crush bends.
