What is SS321 stainless steel and why is it used for exhaust parts?

SS321 is a type of stainless steel that includes titanium. This addition makes it more resistant to oxidation and corrosion at high temperatures, which is common in exhaust systems. It's a well-built choice for applications where durability under heat is important.

What does 'mandrel bend' mean for this elbow?

Mandrel bending means the tube is supported internally during the bending process. This prevents the tube from collapsing or kinking, ensuring the diameter stays consistent throughout the bend. This is important for maintaining smooth exhaust flow and preventing backpressure.

What is the '1D radius' on this bend?

The '1D radius' refers to the tightness of the bend. A 1D radius means the center of the bend is equal to one times the diameter of the tube. This results in a tighter, more compact bend compared to larger radius bends.

About this part

Product Details

Crafted from SS321 stainless steel with a 16-gauge wall thickness, this 45-degree mandrel bend elbow is built for custom exhaust fabrication. The SS321 alloy offers improved high-temperature strength and oxidation resistance compared to standard 304 stainless steel, making it a solid choice for exhaust systems that see a lot of heat. Its 1.75-inch outer diameter and 1-D radius mean it maintains a smooth, consistent bend without kinking, which is crucial for maintaining exhaust flow and preventing backpressure issues.

This elbow is a simple 45-degree bend with no legs, designed to be welded into a custom exhaust setup. The mandrel bending process ensures the tube's diameter stays consistent throughout the bend, unlike crush bends that can restrict flow. This attention to detail in the bending process helps ensure your custom exhaust system performs as intended, whether you're building a performance system or repairing an existing one.
