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

SS321 is a type of stainless steel that contains titanium. This addition helps stabilize the steel at high temperatures, making it more resistant to corrosion and preventing issues like intergranular corrosion that can occur in other stainless steels when heated.

What kind of projects is this tubing typically used for?

This tubing is commonly used for custom exhaust system fabrication, including building headers, mid-pipes, or muffler sections. It's also suitable for repairs where a section of existing exhaust needs to be replaced.

Is this tubing easy to bend or weld?

SS321 stainless steel is generally considered weldable with standard methods like TIG or MIG. While it's strong, its 16-gauge wall thickness makes it manageable for bending with appropriate tools for custom exhaust fabrication.

About this part

Product Details

If you're building a custom exhaust system or repairing an existing one, having the right tubing on hand is key. This 48-inch length of straight tubing from Stainless Bros is made from SS321 stainless steel, a popular choice for exhaust components because it holds up well to high temperatures and corrosive exhaust gases. The 16-gauge wall thickness, which is 0.065 inches, offers a good balance between strength and workability for fabrication.

The 1.5-inch outer diameter is a common size for many exhaust applications, making it versatile for various projects. SS321 stainless steel is known for its added titanium content, which helps prevent carbide precipitation at high temperatures, improving its resistance to intergranular corrosion. This makes it a solid option for exhaust systems that see a lot of heat and stress.
