Stainless steel is an iron alloy composed primarily of iron and chromium. The chromium in the material reacts with oxygen on the surface to create an oxidized "passive layer", which prevents corrosion and rust. While all stainless steels have at least 10.5% chromium content, alloys with higher percentages demonstrate greater corrosion resistance. 
Stainless steel is often alloyed with other elements, such as nickel, carbon, silicon, manganese, and molybdenum, to enhance certain material characteristics. Manufacturers leverage this ability to increase the material's formability, heat resistance, and durability, depending on the needs of the final product.

Surface Finish		Definition	Application
2B		Finished by heat treatment , picking or equipvalent cold rolling , followed by skin pass to obtain adequate luster surface.	With bright and smooth surface ,easy for further grinding to obtain brighter surface ,suitable for medical instruments ,milk containers ,tableware and so on.
BA		Bright heat treatment after cold rolling.	Structual members .etc.kitchen utensil ,cutlery ,eleltric applicances ,medical instruments ,building decorations ,etc.
NO.3/NO.4		Polished with No.150-240 abrasives.	Milky food processing equipment , medicalinstruments ,building decorations.
HL		Finshed by polishing with abrasives of suitable grain size to obtain continuous streaks.	Building decorations ,such as elevators ,escalators ,door etc.
6K/8K		A mirror-like reflective surface ,which is obtained by polishing with successively finer abrasives and buffing extensively with all gritlines are removed.	Buliding entrances,bulkding column casting ,elevator's wall doors ,counters,sculptures etc.
