SUS321 304 Hot Rolled 5mm Plate ASTM A480 HR Structural Steel Sheet
Type 321 has excellent intergranular corrosion resistance after exposure to this temperature range, and this grade resists oxidation up to 1500˚F and has higher creep and stress rupture properties than 304/304L. It also possesses good low temperature toughness and is non-magnetic in the annealed condition.

321 VS 304:
321 stainless steel is basically from 304 stainless steel. They different by a very very small addition of Titanium. The real difference is their carbon content. The higher the carbon content the greater the yield strength. 321 stainless steel has advantages in high temperature environment due to its excellent mechanical properties. Compared with 304 alloy, 321 stainless steel has better ductility and resistance to stress fracture. In addition, 304L can also be used for anti-sensitization and intergranular corrosion.
The real problem with most headers/upipes is a difference in the coefficient of thermal expansion (CTE) As you block gets hot it expands, as it cools it contracts. What you want is a material that expands and contracts at the same rate as your cast iron block. This allows the seals (gaskets/flanges) to undergo less stress. Most leaks (besides improper installation) are caused by this unmatched CTE. That is why stock exhaust manifold is cast iron, which really meany it has a 2% or more carbon content.
Surface Finish:
