What is a mandrel bend?

A mandrel bend is created using a flexible internal support (a mandrel) that prevents the tubing from collapsing or kinking during the bending process. This ensures the inside diameter remains consistent throughout the bend, which is important for exhaust flow.

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 stabilize the carbide precipitation at high temperatures. This makes it more resistant to corrosion and cracking in the extreme heat found in exhaust applications.

What does a 1.5D radius mean for this bend?

The '1.5D' refers to the radius of the bend relative to the diameter of the tube. A 1.5D radius indicates a relatively tight bend, which can be useful for fitting exhaust systems into tight spaces or making sharp turns.

About this part

Product Details

When you're fabricating a custom exhaust system, having the right bends is crucial for a clean, efficient build. This 45-degree mandrel bend elbow from Stainless Bros is made from SS321 stainless steel, a material known for its excellent resistance to high temperatures and corrosion, making it a solid choice for exhaust components.

The 1.5D radius means it has a tighter bend, which can be helpful when space is limited or you need to navigate around other components. Its 16-gauge (0.065-inch) wall thickness offers a good balance between strength and weight for exhaust tubing. Mandrel bending ensures the tube maintains its diameter throughout the bend, preventing kinks and improving exhaust flow compared to crush bends.
