321 stainless steel sheet has good wear resistance in organic acid and inorganic acid of different concentration and temperature, especially in oxidizing medium. It is used to manufacture wear-resistant acid container and conveying pipeline of wear-resistant equipment.
321 stainless steel plate is Ni-Cr-Mo austenitic stainless steel plate. Its properties are very similar to 304 stainless steel plate. However, due to the addition of titanium metal, it has better grain boundary corrosion resistance and high temperature strength and effectively controls the formation of chromium carbide.
321 stainless steel sheet has excellent high temperature stress breaking performance and high temperature anti-latent property, and its stress mechanical properties are superior to 304 stainless steel sheet.

Surface Characteristics and Application:
| Surface | Characteristics and application |
| 1D - No. 1 | Hot rolled, metallic pure, annealed, pickled and heat treated. The most common hot rolled finish. A non reflective, rough surface. Not normally used for decorative applications |
| 2D | Matt, cold rolled, annealed, pickled. This material is cold rolled followed by softening and de-scaling. The effect of cold rolling the material is to produce a smoother, less pitted surface. The surface is not only smooth but of matt grain appearance. Used where a better surface is required or subsequent processing/ finishing is necessary. |
| 2B | Matt glossy, cold rolled, annealed, pickled, skinpassed. This is the general purpose, cold rolled finish and it is suitable for a wide range of applications where stainless steel is specified. It is also suitable for a wide range of subsequent polishing processes such as satin finishing and grinding.. |
| 2R - BA | Mirror glossy, bright annealed. The effect of annealing without the presence of oxygen is to produce a reflective surface on the stainless steel and it is often used in preference to a 2B finish where reflectivity is important, such as catering equipment. The very smooth surface also makes this surface highly suitable for further finishing processes such as mirror polishing and chrome plating. |
| 2G- 4N | No. 4 Finish is characterized by short, parallel polishing lines, which extend uniformly along the length of the coil. No 4 finish gives low gloss and best apparent flatness of panels. For fabricators, the No 4 finish is directional, allowing easy matching of surfaces and refinishing of welds. For end users, the surface can be repaired to remove any service damage. No 4 finish is duller than the other common finishes, 2B and BA and is generally used where lower reflectivity or gloss is required and where welds and other fabrication marks are to be refinished to match the original surface. This is not possible with 2B and difficult with BA. |
| Mirror - 8K | #8 mirror-polished is the top quality surface finish. Surface blemishes are eliminated by the complete finishing process to achieve a mirrorlike appearance. Such fine quality can be achieved without any extra finishing or coating materials being added. the characteristics of high reflectivity and a lustrous shine allow them to complete any kind of architectural or interior decoration. |
