Surface Description of Stainless Steel Plate
| 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, 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, ensuring structural integrity.
Cold working 2507 aligns with most standard stainless steel forming methods. Due to its higher yield strength and lower ductility compared to austenitic steels, fabricators may require enhanced forming forces, larger bending radii, and greater allowances for springback. Techniques like deep drawing and stretch forming are more challenging than with austenitic stainless steel. For deformations exceeding 10% cold work, a solution anneal and quench is recommended for optimal performance.
Post hot or cold forming, 2507 should undergo solution annealing at a minimum of 1925°F, followed by a rapid air or water quench. To achieve peak corrosion resistance, heat-treated products should be pickled and rinsed thoroughly.
2507 boasts exceptional weldability and can be joined to itself or other materials using methods such as SMAW, GTAW, PAW, FCW, or SAW. For optimal duplex weld structures, employ 2507/P100 filler metal.
2507 insulation is typically unnecessary unless used to prevent condensation on cold surfaces. The Interpass
Our stainless steel sheets come in a variety of stunning finishes: brushed, 2B smooth, and 8K mirror, catering to diverse aesthetic and functional needs.
Each stainless steel sheet features a protective film on the finished side that can be easily removed post-fabrication or installation, safeguarding the surface from damage. The back side remains unfinished.
2205 Grade Stainless Steel Sheet is the industry standard, known for its weldability, formability, and excellent corrosion resistance, making it versatile for numerous applications.
