The main factors influencing the 304 stainless steel plate surface roughness
304 stainless steel manufactured by cold rolling, heat treatment, pickling, then through rough roller leveling, called a 2 d surface processing, 2 d can be pickling surface, can also be a rough surface.
Again after pickling with large diameter and high precision polishing roll small reduction of flat (this only a small amount of lower roughness, but can improve the gloss peace straight degrees). 304 stainless steel plate 2b surface processing.
Many factors affect the surface roughness of 304 stainless steel plate, but cold rolling play a leading role, the total quantity of cold rolling surface roughness determines the range of 0.1 ~ 1.0 microns. Due to the different performance requirements (such as pay to prevent scratches and paint, etc.). Need to the rough surface, choose 2 d, the surface roughness is 0.5 ~ 3.0 microns. Rolling steel plate surface processing of high reflectivity is in reduction of dry nitrogen/hydrogen atmosphere through bright annealing, do not need to pickling and passivation.
