With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
Grade 304L is more readily available in most product forms, and so is generally used in preference to 321 if the requirement is simply for resistance to intergranular corrosion after welding. However 304L has lower hot strength than 321 and so is not the best choice if the requirement is resistance to an operating environment over about 500 C.
321 is non-heat treatable and non-magnetic in the annealed condition. This alloy contains chromium, nickel, and titanium. It is used principally for applications involving welding or sustained elevated temperature operations. 321.

Type 321 is a stabilized stainless steel (addition of Titanium) offering excellent resistance to intergranular corrosion attack following exposure to high temperatures. It's often used in aerospace, high temperature and tool wrap applications. Type 321 is available at Sidecuts.com in both COIL and SHEET form.
The annealing temperature range for Type 321 is 1800 to 2000 F (928 to 1093 C). While the primary purpose of annealing is to obtain softness and high ductility, this steel may also be stress relief annealed within the carbide precipitation range 800 to 1500 F (427 to 816 C), without any danger of subsequent intergranular corrosion.
321 has excellent low temperature properties with increased tensile and yield strengths with little loss of toughness in the annealed condition.

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.
This group of materials includes alloys such as 321, 347, Alloy 20 and Alloy 625. Solution annealing these alloys involves heating them to at least 1850 F to place the constituents into solid solution. Stabilize annealing is performed at a lower temperature, usually around 1650 - 1750 F,best ss 321 annealed
The low carbon (304L or 316L) or the stabilised (321 or 347) types should not be at risk from corrosion sensitisation during stress relieving treatments. Stress relieving treatments for austenitic stainless steels. The table shows alternative treatments in order of preference.

You also will not find a good match for 321 SS in the manufacturer's catalogs. The closest thing to it will be the austenitic stainless steels, which is a broad range. The specs also tend to be geared towards forged and/or annealed bar. 321 is more difficult than 316SS. It's been quite a while since I've turned 321.
Stainless steels are generally heat-treated based on the stainless steel type and reasons for carrying out the treatment. Heat treatment methods, such as stress relieving, hardening and annealing, strengthen the ductility and corrosion resistance properties of the metal that is modified during best ss 321 annealed
How to Anneal Stainless Steel to Soften It. A. Hello John! The stainless you have is likely in the cold rolled condition. Annealing is commonly done at 1900 F or so, for roughly an hour. You want to cool it fairly fast, especially through the 1500 F to 800 F temperature range, to avoid 'sensitization'.
Difference Between 304 304L and 321. 304 stainless steel is low carbon chromium nickel stainless and heat resisting steel somewhat superior to Type 302 in corrosion resistance. 321 stainless steel is known as stabilized grades of stainless steel, is Chromium nickel steel containing titanium.
The key feature of 321 stainless is its resistance to inter-granular corrosion. It contains titanium, which stabilizes against chromium carbide formation. 321 Stainless Steel Bar - (annealed condition) | TW Metals
321 Stainless is nasty stuff to drill. I recently had an application to drill 321 SS that was hardened and annealed according to the supplier to RC 32-36 (340Bhn max)We were drilling 2mm (.0787") diameter holes 10mm (.393")deep.
321 stainless aerospace tubing is made from an austenitic stainless steel offering an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500F (427 to 816C).

THE HEAT TREAT DOCTOR: Stainless Steels Part Two: Heat Treatment Techniques by Daniel H. Herring Posted: June 14, 2006 Heat treating of stainless steels depends to a great extent on the type (wrought or cast) and grade of stainless steel, as well as the reason for the treatment, most often to
Type 321 contains titanium for greater resistance to corrosion and pitting. Excellent corrosion resistance and a smooth bore make it suitable for water, gasses, oil, chemicals and processes where particulate build needs to be kept to a minimum. Tubing may be flared and is compatible with conventional compression or flare fittings.

And in this respect 321 SS has a slight advantage over 304 SS. Fatigue or endurance limits (strength in bending) of austenitic stainless steels in the annealed condition are about one-half the tensile strength.Typical tensile and endurance limits for these alloys (annealed) are presented in the table below:
Alloy 321 (UNS S32100) is a titanium stabilized austenitic stainless steel plate with good corrosion resistance. It has great resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 1500F (427 816C).
Soft and Ductile - Type 304 annealed stainless steel (304 ss) or 18/8 chrome-nickel Stainless Steel Strip differs from Type 302 only in its low carbon content and in its slight increase in the chrome and nickel percentages. It has a high degree of ductility, excellent drawing, forming and spinning properties.
