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 tube maintains its original round shape and diameter, which is crucial for smooth exhaust flow.

Why use SS321 stainless steel for exhaust?

SS321 stainless steel is an alloy that includes titanium, which helps stabilize the carbide structure at high temperatures. This makes it more resistant to sensitization and intergranular corrosion in the high-heat environment of an exhaust system compared to standard 304 stainless steel.

What does '1.5D radius' mean?

The '1.5D radius' refers to the bend radius being 1.5 times the outer diameter of the tube. For a 1.625-inch tube, this means the center of the bend forms a radius of approximately 2.44 inches. This indicates a relatively tighter bend compared to larger radii.

About this part

Product Details

This is a 45-degree mandrel bend elbow from Stainless Bros, made from SS321 stainless steel. It has an outer diameter of 1.625 inches and a wall thickness of 16 gauge, or .065 inches. The bend radius is 1.5 times the tube diameter, which is a tighter radius suitable for specific fabrication needs where space is limited.

Mandrel bending means the tube maintains its round shape during the bend, unlike crush bends which can deform the tubing. This is important for maintaining consistent exhaust flow and preventing restrictions. SS321 stainless steel is a good choice for exhaust components because it offers improved corrosion resistance and can handle high temperatures well, especially compared to standard 304 stainless steel, due to the addition of titanium.

This elbow is intended for custom exhaust system fabrication or repair. You'll use this when you need to make a precise 45-degree turn in your exhaust piping and want to ensure smooth flow and durability.
