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 stronger in extreme heat compared to standard 304 stainless steel.

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

The '1.5D radius' refers to the centerline radius of the bend. It means the radius is 1.5 times the diameter of the pipe. A smaller D-radius like this indicates a tighter, more compact bend, which is often useful in custom exhaust routing where space is limited.

What is the advantage of mandrel bending?

Mandrel bending uses a "biscuit" or mandrel inside the tube during the bending process. This prevents the tube from collapsing or kinking, ensuring the internal diameter remains consistent throughout the bend. This consistency is crucial for optimal exhaust flow and performance in custom systems.

About this part

Product Details

Stainless Bros is known for providing quality exhaust fabrication components. This 3.5-inch 90-degree mandrel bend elbow is crafted from SS321 stainless steel, a material often chosen for its enhanced high-temperature strength and corrosion resistance, making it a solid choice for custom exhaust systems. The 1.5D radius means it has a tighter bend compared to a standard 3D radius, which can be useful when space is limited in custom fabrication projects.

This elbow features a 16-gauge wall thickness, or .065 inches, offering a good balance of durability and weldability for custom exhaust work. The mandrel bending process ensures that the pipe maintains its diameter throughout the bend, preventing kinks and allowing for smoother exhaust flow compared to crush bends. This particular elbow is designed without any legs, meaning it's a clean 90-degree turn ready for your specific welding and fitting needs in a custom exhaust build.
