We offer a wide range of surface finishes for enhanced product appeal and functional applications. Whether straight from the mill or further processed by our service centres, our products come with industry-leading quality.

Surface finishes count for more than just aesthetic considerations, as surface quality or surface finish also affects the material´s sensitivity to corrosion and its cleanability.

Cold rolled surface finishes

By means of further rolling of the steel in a cold state, both its surface smoothness and thickness accuracy are improved. Since stainless steel is cold hardened, that is, it is hardened by the cold-working process, it has to be annealed after the rolling so as to regain its softness and working characteristics. This is most often carried out in an ordinary air atmosphere, which again results in an oxide that has to be removed by pickling in an acid bath.

Most surfaces can be temporarily protected by a removable plastic film which is applied before delivery.

Further finishing actions are outlined in the chart below:

Hot rolled plate and sheet surface finishes

All steel plate and sheet is hot-rolled as a first rolling step, after which it is annealed in order to attain homogeneous material characteristics. Annealing produces an oxide on the steel, which is removed by shot blasting and by pickling in an acid bath.

As a result of these manufacturing operations, the steel acquires a relatively coarse, matt grey surface denoted 1D, with an Ra value in the order of 2-8 µm; depending on steel grade and some process parameters. Localised grinding marks may appear on plate material, but have no practical implications for the use of the steel. Hot rolled plate of this finish is mostly used for heavy process equipment and in thickness from around 5 mm and upward.
