WHAT IS 321 STAINLESS STEEL?
321 Stainless Steel, like 304 Stainless Steel, is a low carbon, chromium nickel alloy with good intergranular corrosion resistance. 304 Stainless has good corrosion resistance up to 1,562°F (850°C); whereas, 321 Stainless allows for a higher temperature limit, including long term exposure to high temperatures, up to 1,652°F (900°C) due to the addition of Titanium, which acts as a stabilizer. 321 Stainless Steel's main advantage over 304 Stainless Steel in high temperature environments is that 321 Stainless offers better resistance to stress fractures. This higher resistance to stress fractures has advantages in automotive applications where differences in the Coefficient of Thermal Expansion (heat-related expansion and contraction which occurs at different rates) are greatest — typically between the engine and the manifold(s). 321 Stainless is better suited to handle this type of heat-related stress, as compared to 304 Stainless. While 304 Stainless is suitable for a wide variety of automotive applications, 321 Stainless is the superior choice for high temperature applications, and especially applications that see long term exposure to high temperatures like race cars, and offers a higher resistance to stress fractures and heat-related corrosion. For welding 321 Stainless Steel (including welding 321 Stainless to 304 Stainless) we recommend ER347 Filler Rod.
