Polished Hot Rolled 430 Steel Sheet SURFACE FINISH
SURFACE FINISH | CHARACTERISTICS | APPLICATION |
BA | Cold rolled, bright annealed and skin-passed, the product have excellent brightness and good reflexivity like mirror. | Kitchen utensil, kitchenware, Cookware, architectural purpose. |
2B | Finished by heat treatment, pickling after cold rolling, followed by skin pass line to more brighter and smooth surface. | General application medical instruments, tableware. |
NO.4 | Polished with abrasive belt of grit#150~#180,have better brightness with discontinuous coarse stria. | Kitchen utensils, kitchen sink, architectural purpose, tableware, |
6K / 8K / Mirror | A mirror-like reflective surface by polishing with finer abrasives over 600 or 800 mesh. | Reflector, mirror, interior- exterior decoration for building. |
Hairline | Polished with abrasive belt of grit#150~#320 on the NO.4 finish and has continuous streaks. | Architecture industries, escalators, elevator, kitchenware, vehicles, |
Etched | Involves using liquid chemicals or etchants to take off the substrate material. | Decorative door or wall surface, interior decoration and architectural purpose. |
Embossed | A moulded or carved decoration or design on the surface so that it is raised above the surface in low relief | Decorative door or wall surface, interior decoration and architectural purpose. |
Type 430 is a ferritic stainless steel with corrosion resistance approaching that of 304/304L stainless steel. This grade does not work harden rapidly and can be formed using both mild stretch forming, bending, or drawing operations. This grade is used in a variety of interior and exterior cosmetic applications where corrosion resistance is more important than strength.
