The Fabricator’s Choice for Building Turbo Manifolds & Merge Collectors!

The Ace Race Parts brand of Schedule 10 321 Stainless Pipe isthe perfect match for our Stainless Weld Els for fabricating turbo manifolds. Our 321 StainlessPipeoffers superior corrosion resistance in high temperature applications especially applications that will see extended periods ofwide open throttle(eg: a track car) or will see repeated high heat cycling (eg: a drag car that sees significant cooling between passes). With a slight addition of Titanium to stabilize the alloy at high temperatures, 321 Stainless is an excellent choice for turbo manifolds that will be exposed to high levels of heat over a prolonged period of time.

304 Stainlessvs 321 Stainless

One major chemical difference between 304 and 321 Stainless is the addition of Titanium (Ti) in 321 stainless to help “stabilize” the alloy and to reduce the risk of corrosion in the heat-affected zone. When 304 Stainless is heated above 1,292F for an extended period of time it may suffer from weld decay. Weld decay is reduced by the addition of titanium, making 321 Stainless ideal for use in turbo exhaust manifolds and other exhaust products that see high levels of heat over prolonged periods of time. Although 304 Stainless is more than suitable for most turbo manifold and other exhaust applications, 321 Stainless is the superior choice for heat-related corrosion resistance.
