Mill Finish Stainless Steel Sheet

The most common stainless steel finish is 2b.

Mill finish stainless steel sheet.

Although not regarded as commercially aesthetic it is generally a consistent dull finish with very few if any surface imperfections on the a side of the sheet. Mill finishes guide to stainless steel finishes 3 1d hot rolled and annealed and with the mill scale removed this surface condition is classified as a 1d finish. It then receives a final light pass on polished rolls known as a pinch pass. Typical ra would be 3 50 7 50 µm 140 300 µin.

From mill finishes to applied finishes the stainless steel finishes that are applied to the surface of your stainless steel can play a bigger role than you may realize. Our 316l stainless steel sheet 2b finish will not have a protective film to prevent scratching so the 316l stainless steel will commonly have scratching not gouging from when it is cut to size fabricated shipped etc. 316l stainless steel sheet 2b finish has a mill finish which is smooth and not the brushed finish commonly seen on kitchen appliances. This surface which is found on thicker sheets and plate is slightly coarse with very low reflectivity.

Unpolished stainless steel textures mill finishhas a dull gray matte appearance that is produced by cold rolling to a specified thickness annealing and descaling. This makes it more ductile and workable. Stainless steel stainless steel sheet mill finish is a dull grey finish. It resembles a very hazy mirror with some reflection evident.

Hot rolled softened annealed with the surface de scaled. While some products may only require standard stainless steel finishes others may need something extra in order to enhance surface appearances improve environmental performance or even reduce safety concerns. Stainless steel is polished by mills in a range of forms e g. 2b mill finishis a bright defect free finish that is produced by a final light cold roll pass on polished rolls.

The 2b mill finish is achieved with an additional light cold roll pass and is the standard finish for 201 301 304 304l and 316l stainless steel. Annealing consists of heating the steel and letting it cool down slowly to remove internal stress and reduce hardness. It is primarily used for non decorative purposes. It is important therefore to check that the finish is available in the form required.

1d stainless steel finish hot rolled annealed pickled after the steel is hot rolled in the mill it is then put through a heat treatment called annealing. 1d 1e hot rolled plate. 2b mill finish the stainless steel is cold rolled softened and descaled similar to the process of a 2d finish. The steel remains gray in appearance but the final pass on polished rolls produces a smoother brighter surface than 2d finish.

A bright cold rolled finish is the most commonly mill finish for light gauge stainless steel sheet.
