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

SS321 is a type of stainless steel that contains titanium. This addition makes it more resistant to high temperatures and corrosion, especially in exhaust systems where components are exposed to extreme heat and exhaust gases.

What does '1D radius' mean for this exhaust elbow?

A 1D radius means the center of the bend is one tube diameter away from the outer wall of the tube. This results in a tighter bend compared to larger radii, which can be useful for fitting exhaust components into tight spaces while still allowing for decent exhaust flow.

What is the advantage of mandrel bending?

Mandrel bending ensures the tube maintains its original round shape and diameter throughout the bend. This prevents kinking or flattening, which is important for maintaining smooth exhaust gas flow and preventing performance loss in custom exhaust systems.

About this part

Product Details

This 3-inch 90-degree elbow 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 fabrication projects. The 1D radius means the bend is tight, with the center of the bend being one diameter away from the tube's outer wall, which helps maintain good exhaust flow without excessive restriction. It's constructed with a 16-gauge wall thickness, providing a good balance of strength and weldability for custom exhaust systems.

The mandrel bending process ensures that the tube maintains its round shape and diameter throughout the bend, preventing kinks or flattening that could impede exhaust gas flow. This is crucial for performance applications where smooth flow is important. The 'no leg' design means the ends are cut square, ready for you to weld directly into your custom exhaust setup. This part is ideal for fabricators building custom exhaust headers, downpipes, or cat-back systems where precise bends are needed.
