Titanium stabilized chromium nickel austenitic stainless steel
- Type 321 is a titanium stabilized chromium nickel austenitic stainless steel with corrosion resistance similar to 304/304L. This grade is typically used in the 800-1500˚F temperature range where it is stabilized against chromium carbide precipitation by the addition of titanium, which results in the precipitation of titanium carbides.

Oct 23, 2001 · Grade 321H is a modification of 321 with higher carbon content, to provide improved high-temperature strength. A limitation with 321 is that titanium does not transfer well across a high-temperature arc, so it is not recommended as a welding consumable.
Chemical Composition of 321 and 321H Stainless Steel Plate. The difference between 321 and 321H grades lies in the amount of carbon contained within each metal. 321 has at most 0.08% while 321H contains between 0.04% and 0.10% carbon. They both contain at most 2.0% manganese, 0.75% silicon and 0.045% phosphorous.
Grade 321H is a modification of 321 with a controlled higher carbon content, to provide improved high temperature strength. A limitation with 321 is that titanium does not transfer well across a welding arc, so is not usable as a welding consumable.
Nov 23, 2020 · Type 321 contains a minimum of 5 × (C% + N%) titanium, and type 347 a minimum of 8 × C% niobium. Nitrogen must be considered when titanium is used as a stabilizer, not because the precipitation of chromium nitride is a problem in austenitic steels, but because titanium nitride is very stable and it also depletes the titanium added.
Description. Type 321 is a titanium stabilized chromium nickel austenitic stainless steel with corrosion resistance similar to 304/304L. This grade is typically used in the 800-1500˚F temperature range where it is stabilized against chromium carbide precipitation by the addition of titanium, which results in the precipitation of titanium carbides.
Overview. Reinforced with titanium, 321 stainless steel excels in high temperature environments, providing resistance to cracking and corrosion. Additionally, 321 stainless resists scaling at higher temperatures. The addition of titanium means that welding is not suggested for this alloy.
