304 stainless steel surface quality inspection

304 stainless steel surface quality is good or bad, mainly determined by the heat treatment after the pickling process, if the previous heat treatment process formed by the surface oxide thickness, or uneven organization, then pickling can not improve the surface finish and uniformity. So should pay full attention to heat treatment before heating or heat treatment surface cleaning.

If the thickness of the surface of the stainless steel plate is not uniform, the thickness of the surface of the base metal below the thin surface and the lower surface of the base metal is also different, and the surface oxide of the surface oxide is dissolved and oxidized Different, so the steel surface is not uniform. Therefore, when the heat treatment is heated, it is necessary to uniformly form the scale.
