What is SS321 stainless steel good for?

SS321 stainless steel is a popular choice for exhaust components because it offers good resistance to high temperatures and oxidation. This makes it well-suited for applications where exhaust gases can reach significant heat levels.

What does 'mandrel bend' mean for an exhaust tube?

A mandrel bend is created using a flexible mandrel inside the tube during the bending process. This prevents the tube from collapsing or kinking, ensuring the internal diameter stays consistent throughout the bend and doesn't restrict exhaust flow.

What is the '1.5D radius' on this elbow?

The '1.5D radius' refers to the centerline radius of the bend. In this case, it's 1.5 times the diameter of the tube (1.5 inches x 1.5 = 2.25-inch radius). This indicates a relatively gentle curve, which helps maintain smooth airflow compared to tighter bends.

About this part

Product Details

If you're building a custom exhaust system or fabricating a unique intake setup, having the right bends is key. This 45-degree elbow from Stainless Bros is made from SS321 stainless steel, a material known for its good performance in high-temperature environments. The 1.5-inch diameter and 1.5D radius mean it offers a smooth, consistent bend that won't restrict flow.

The mandrel bending process ensures the tube maintains its shape and diameter through the curve, which is crucial for maximizing airflow. This elbow is 16-gauge thick with a .065-inch wall, offering a good balance of strength and weldability for fabrication projects. It's designed without legs, meaning you'll need to weld it directly into your tubing setup.
