Surface quality inspection methods and precautions of 304 stainless steel pipe

Number of Views: 212Release time: August 18, 2020

304 stainless steel pipeQuality inspection overview: the black and white quality of 304 stainless steel pipe is mainly determined by the pickling process after heat treatment. If the oxide scale formed by the previous heat treatment process is thick or the structure is uneven, pickling cannot improve the surface finish and evenness. Therefore, we should fully face the heating of heat treatment or the general cleaning before heat treatment.
