Now the most common finish of 304L stainless steel plate is bright and matte. Matt surface stainless steel plate after brushing treatment than the general bright surface stainless steel plate more wear-resistant and looks more upscale, which many consumers like.
But after the brushed treatment of 304L stainless steel plate corrosion resistance and rust resistance will be relatively lower, if the usual maintenance is not appropriate, maybe the bright surface stainless steel plate early rust.
304L stainless steel is one of the many steel grades of austenitic stainless steel, the main content is carbon, nickel, chromium, and other elements, chromium elements can form a layer of chromium-rich protective film on the surface of 304L stainless steel plate, thus preventing further oxidation of 304L stainless steel plate and corrosion rust.
304L stainless steel plate after the brushing treatment on the surface of the chromium-rich protective film will be destroyed, 304L stainless steel plate corrosion resistance and rust resistance will follow the reduction if the wind, sun, and rain in the harsh environment are very easy to corrosion and rust phenomenon.
If you must do brushing on a 304L stainless steel plate, then please do a good job in the usual use of maintenance and maintenance, avoid direct contact with corrosive substances (such as chemicals).
