321 is similar to 304, but uses titanium as a stabiliser. They differ in that they are resistant to intergranular corrosion after heating to temperatures in the carbide precipitation range. Applications include aircraft exhaust manifolds, furnace parts, heat exchangers, furnace parts etc.
The Type 321 austenitic stainless steel is susceptible to stress corrosion cracking (SCC) in halides similar to Type 304 stainless steel. This results because of their similarity in nickel content. Conditions which cause SCC are: (1) presence of halide ion (generally chloride), (2) residual tensile stresses, and (3) environmental temperatures in excess of about 120 F (49 C).
The key feature of 321 stainless is its resistance to inter-granular corrosion. It contains titanium, which stabilizes against chromium carbide formation. This material is also stronger than 304 stainless.
The titanium content of 321 stainless steel preserves corrosion resistance around weld points. This material maintains its corrosion resistance in temperatures up to 1500 F. Sheets with a maximum heating-treating temperature of 2000 F are often used as a heat-treating wrap for large and odd-sized parts; they are furnished with a crimping tool.
An austenitic chromium-nickel-titanium stainless steel, Alloy 321 offers outstanding performance at temperatures up to 870C. Whilst retaining good strength and corrosion resistance when exposed to high temperatures, Alloy 321 will also maintain its strength and toughness at sub-zero temperatures.

This grade cannot be hardened by thermal treatment. Cold Working Grade 301 and its low carbon variants are used where a high strength stainless steel is required. The grades work harden at the very
Type 321 is a chromium-nickel stainless steel and with the addition of titanium, type 321 is resistant to intergranular corrosion. Type 321's general corrosion is less than Type 302. Type 321 is used where resistance to intergranular corrosion is required and where the parts are subjected to sustained heating or cooling within the range of 800 ss 321 yield strength
316 / 316L are austenitic stainless steels that contain molybdenum, which increases their resistance to many chemical corrodents and marine environments. 316L is an extra low carbon version of 316 stainless steel. These materials are more resistant to general corrosion and pitting/crevices than conventional austenitic stainless steels.
This titanium addition reduces or prevents carbide precipitation during welding and in 800 1500F service. It also improves the elevated temperature properties of the alloy. Type 321 provides excellent resistance to oxidation and corrosion and possesses good creep strength.
Additionally, 321 stainless resists scaling at higher temperatures. The addition of titanium means that welding is not suggested for this alloy. Typically used in aircraft engines, expansion joints, thermal equipment, refinery equipment, and high temperature chemical processing equipment.
AISI 321 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. 321 is the AISI designation for this material. S32100 is the UNS number. Additionally, the British Standard (BS) designation is 321S12. The properties of AISI 321 stainless steel include two common variations.
numbered stainless steels frequently used for high-temperature service are presented in the tables beginning on page 32.) Creep Over about 900F (482C), deformation under stress is plastic rather than elastic, so the yield point as determined by the short-time tensile test is higher than the creep or stress-rupture strength.
321 stainless is a titanium stabilized grade commonly used for service in the 1000-1600F temperature range. For service temperatures up to about 1600F, a stabilizing treatment at 1550-1650F, air cool, may be used to provide optimum resistance to intergranular corrosion and to polythionic acid stress corrosion cracking.
