3.000″ 16ga Tight Radius 90° Mandrel Bend 321 Stainless Ace Race Parts

Ace Race Parts 321 Stainless Steel Mandrel Bends are a high quality, cost effective solution automotive headers and exhaust systems, as well as aircraft exhaust manifolds. For high temperature applications, such as turbo manifolds, high horsepower exhaust applications, and even aircraft manifolds, 321 Stainless is a superior choice when compared to 304 Stainless. 321 Stainless has a similar chemical composition to 304 stainless; however, 321 Stainless uses Titanium as a stabilizing element and offers much higher strength and temperature resistance as compared to 304 Stainless material. In the 800°F to 1,562°F temperature range, 321 Stainless is not susceptible to the same level of corrosion as 304 Stainless and is the material grade of choice for applications with temperature ranges up to 1,652°F (intermittent service) and 1,697°F (continuous service).

Our 321 Stainless Mandrel Bends are now available in both 45° and 90° bend options with outside diameters ranging from 1.500″ to 3.500″. Our Mandrel Bends are precision bent using a CNC mandrel bender in an ISO 9001 certified facility to ensure that the degree and centerline radius of each bend is consistent and free of defects. After the bending process is completed each mandrel bend is then de-burred and polished to a 600 grit finish to ensure a clean finish on the ends and surface.

Our mandrel bends are a perfect match for our stainless steel Tube, stainless steel V-Band Clamps and Flanges, Tube Size Fittings, Exhaust Flanges, and Flex Couplings and Flex Bellows.

What is Tube and How is it Different from Pipe?

Tube size material is measured by the actual outside diameter (OD) and wall thickness. Whereas, Nominal Pipe Size (NPS) is an industry designation, or “trade size”, and it is does not reference the actual measured size of the material. Even the most experienced fabricators are sometimes confused by the industry’s terminology and method of sizing. Tube size material is not compatible with pipe size material. Many times the words “pipe” and “tube” are use to describe straight lengths of material (eg: exhaust “piping”); however, the industry standard term for this material is “tube”. 

Note: Please be sure to verify that this tube size material meets the requirements of your project. It is the customer’s responsibility to verify the compatibility of the items in their shopping cart. Ace Race Parts is not responsible for orders with mismatched or incompatible products.
