Vibrant 321 Stainless Steel 180 Degree Mandrel Bend 2.25in OD x 3.375in CLR 18 Gauge Wall Thickness

This 180-degree mandrel bend is made from 321 stainless steel, featuring an 18-gauge wall thickness and a 2.25-inch outer diameter. The 321 stainless steel alloy is chosen for its ability to handle prolonged, elevated operating temperatures, ranging from 800°F to 1500°F, making it a solid choice for custom exhaust systems, especially in forced induction applications where heat is a significant factor.

Compared to 304 stainless steel, 321 offers improved corrosion resistance and better performance under tensile stress, which helps prevent stress fractures over time. The mandrel bending process ensures that the tube maintains a consistent diameter throughout the bend, preventing kinks and maintaining smooth exhaust flow, which is crucial for performance. This particular bend has a centerline radius of 3.375 inches and 6-inch leg lengths from the tangent point.
