Stainless Steel Plate Surface Description
| Finish Designation | Method and degree of finish |
| No.1 | After hot rolling, heat treatment, pickling or other equivalent treatment is applied. |
| No.2D | Annealing and pickling are performed after cold rolling; material is soft with surface of silver-white luster; used for general applications and deep drawing. |
| No.2B | After 2D finish, skin pass rolling is performed to obtain a more suitable luster; the surface becomes very exquisite; used for general applications. |
| No.3 | Intermediate 100-120 grit finish; used for applications in which surface polishing is performed after shaping. |
| No.4 | General 150-180 grit finish; used for restaurants and kitchen equipment and tools. |
| #240 | 240 grit finish; used when a finer finish than No. 4 is required; typically for restaurants and kitchen equipment and tools. |
| #320 | 320 grit finish polished product. |
| HL | This finish is performed by continuous linear polishing using an abrasive of appropriate grain size; mainly used for architectural applications. |

General Corrosion
For optimal hot working, the Baosteel 2507 should be processed between 1875°F and 2250°F, followed by a solution anneal at a minimum of 1925°F and a rapid air or water quench.
The Baosteel 2507 is compatible with most stainless steel forming methods. Due to its higher yield strength and lower ductility compared to austenitic steels, fabricators should use greater forming forces, larger bending radii, and higher allowances for springback. Processes like deep drawing and stretch forming are more challenging with 2507. When deformation exceeds 10%, solution annealing and quenching are recommended.
Post hot or cold forming, the Baosteel 2507 should be solution annealed at a minimum of 1925°F, followed by rapid air or water quenching. To maximize corrosion resistance, heat-treated products should be pickled and rinsed.
Renowned for its weldability, the Baosteel 2507 can be joined using various techniques, including SMAW, GTAW, PAW, FCW, or SAW. For optimal duplex weld structures, pairing with 2507/P100 filler metal is recommended.
2507 is not required, except to prevent condensation on cold metal. The Interpass
Our Baosteel 2507 stainless steel sheets are available in various exquisite finishes: brushed, 2B smooth, or 8K mirror, catering to diverse aesthetic and functional needs.
Each stainless steel sheet's finished side is coated with a protective film, which can be easily peeled off post-fabrication or installation, safeguarding the material's surface from damage. The back side remains unfinished.
While the 2205 grade is widely used for its weldability, formability, and good corrosion resistance, the Baosteel 2507 offers superior performance for more demanding applications.
