Stainless Steel Surface Finishes

Surface Finish		Definition	Application
	2B	Those finished, after cold rolling, by heat treatment, pickling, or other equivalent treatment, and lastly by cold rolling to give an appropriate luster.	Medical equipment, food industry, construction material, kitchen utensils
	BA	Those processed with bright heat treatment after cold rolling.	Kitchen utensils, electric equipment, building construction
	No.3	Those with brushed, coarse-grain finishes running in one direction were achieved using 100-120 grit abrasives, resulting in moderate reflectivity.	Kitchen equipment, interior decorative panels
	No.4	Those finished by polishing with No.150 to No.180 abrasives specified in JIS R6001.	Kitchen utensils, building construction, medical equipment
	No.5	Also known as satin or brushed finish, those featuring a matte, non-reflective look with fine parallel lines, achieved by using a series of abrasive materials to develop a uniform and consistent surface texture.	Architectural design, decorative structures
	No.8 (Mirror)	Using very fine abrasive polish and buff to produce a sheet with a bright mirror-like surface.	Building architectural panel, elevator, interior decoration, window frames, curtain walls, kitchen furniture
	HL	Those finished by polishing so as to give continuous polishing streaks by using abrasive of suitable grain size.	Building construction
	Etching	The etched technique is utilized to create unique patterns or designs on metal surfaces. The depth of the grooved surface can be made by machine depending on the different etching.	Building construction panel, elevator, interior decoration
	SB	Scotch Brite finishes feature a unidirectional texture and uniform grain, achieved through brushing with finer abrasives, resulting in a soft matte appearance and low-level reflectivity.	Home appliances, elevator panels, kitchen applications, automotive trim
	Ti-Coating	The Ti-coating technique is a booming technology transferring from aerospace technology and applies the principle of ion exchange to adhere titanium ions onto the material surface under vacuum and high-temperature conditions.	Building decoration, artistry
