What is a 1D radius bend?

A 1D radius bend means the center of the bend is equal to the diameter of the tubing. This results in a tighter bend compared to larger radius bends, which is useful for fitting exhaust systems into tight spaces.

Why is SS321 stainless steel used for exhaust components?

SS321 stainless steel is a popular choice for exhaust systems because it contains titanium, which helps prevent carbide precipitation at high temperatures. This makes it more resistant to corrosion and cracking in demanding exhaust environments.

What is the benefit of mandrel bending?

Mandrel bending uses a "mandrel" inside the tube during the bending process. This prevents the tube from collapsing or kinking, ensuring the diameter remains consistent throughout the bend. This consistency is crucial for maintaining smooth exhaust flow and preventing turbulence.

About this part

Product Details

If you're building a custom exhaust system, a clean 45-degree bend is essential for routing tubing around obstacles. This elbow from Stainless Bros is made from SS321 stainless steel, a material known for its strength and resistance to high temperatures, making it a solid choice for exhaust work.

The 1D radius means the bend is tight, with the center of the bend being only one times the tube's diameter away from the tube's edge. This tight radius is useful when space is limited. The tubing itself is 16 gauge thick, or .065 inches, which offers a good balance of strength for welding and durability without adding excessive weight. The mandrel bending process ensures the tube's diameter stays consistent throughout the bend, preventing kinks and maintaining smooth exhaust flow.
