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

SS321 is a type of stainless steel that includes titanium. This addition helps it resist carbide precipitation at high temperatures, making it more durable and corrosion-resistant in demanding exhaust environments compared to standard stainless steel.

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 edge of the tube. This creates a tighter, more compact bend, which is useful when space is limited in a custom exhaust system.

What is the wall thickness of this tubing?

This exhaust tubing has a 16-gauge wall thickness, which measures 0.065 inches. This provides a good balance of strength for welding and durability without adding excessive weight.

About this part

Product Details

This is a 3.5-inch, 90-degree elbow made from SS321 stainless steel by Stainless Bros. It’s designed for custom exhaust fabrication where you need to make a tight bend. The 1D radius means the center of the bend is one diameter away from the tube's edge, allowing for a compact turn without kinking.

The tubing itself is 16-gauge thick, with a wall thickness of 0.065 inches, which is strong enough for most exhaust applications. SS321 stainless steel is a popular choice for exhaust components because it holds up well to high temperatures and resists corrosion, especially important in the exhaust system where heat and moisture are constant factors. This elbow has no leg, meaning both ends are open for welding into your custom exhaust setup.
