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

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 cracking in demanding exhaust environments. It's a popular choice for custom exhaust components that experience significant heat.

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

The '1.5D radius' refers to the bend's tightness. 'D' represents the tube's outer diameter (1.625 inches in this case). A 1.5D radius means the center of the bend is 1.5 times the tube diameter away from the tube's centerline. This allows for a more compact bend compared to larger radius elbows.

What does 'no leg' mean for this exhaust elbow?

This elbow is a straight 45-degree bend piece without any additional straight sections (legs) attached to either end. It's designed to be cut to your specific length requirements and welded directly into your custom exhaust system.

About this part

Product Details

This 45-degree elbow is made from SS321 stainless steel, a material known for its good resistance to high temperatures and corrosion, making it a solid choice for exhaust fabrication projects. The tubing measures 1.625 inches in outer diameter and has a wall thickness of 16 gauge, or .065 inches, which offers a good balance between strength and weldability for custom exhaust systems.

It features a 1.5D radius bend, meaning the center of the bend is 1.5 times the tube's diameter away from the tube's centerline. This tighter radius is useful when space is limited, allowing you to route exhaust pipes more compactly. The mandrel bending process ensures the tube maintains its round shape and doesn't collapse during the bend, which is crucial for maintaining smooth exhaust flow and preventing restrictions.

This elbow is sold without any legs, meaning it's a straight 45-degree bend piece ready for you to cut and weld into your custom exhaust setup. It's a popular choice for fabricators working on custom headers, downpipes, or any application where precise exhaust routing is needed.
