AI Technical Summary
Existing stainless steel sheets have shortcomings in achieving both high whiteness and high image clarity. Current technologies struggle to achieve both simultaneously, and design evaluations that primarily rely on gloss and whiteness indicators fail to fully reflect image clarity.
By roughening and planarizing the surface of stainless steel plates, the horizontal difference Sk at the center, the height Spk of the protruding peak, and the load area ratio Smr2 that distinguishes the center from the protruding valley are controlled within a specific range. This is combined with different steel grade processes, including the manufacturing methods of austenitic and ferritic-austenitic duplex stainless steel plates, as well as the heat treatment and pickling processes of ferritic and martensitic stainless steel plates.
High whiteness and high image clarity of stainless steel plates were achieved, and surface properties were within the optimized range, meeting design requirements.
