2b Finish Stainless Steel Sheet

2d this finish is also achieved by cold rolling heat treating and pickling but unlike 2b does not receive the light rolling.

2b finish stainless steel sheet. The steel remains gray in appearance but the final pass on polished rolls produces a smoother brighter surface than 2d finish. 2b is the most widely used stainless steel surface finish. It then receives a final light pass on polished rolls known as a pinch pass. It is also used in some architectural applications that will not be closely examined for uniformity of finish such as downpipes and gutters.

2b bright cold rolled a bright cold rolled finish is the most commonly mill finish for light gauge stainless steel sheet. 2b mill finish the stainless steel is cold rolled softened and descaled similar to the process of a 2d finish. It is primarily used for non. This method is cold rolled heat treated pickled and pinch passed resulting a slightly reflective surface similar to a cloudy mirror.

Such common stainless steel grades as 201 304 304l and 316l come in a standard 2b finish. 2b finish similar to 2d see below but has a comparatively shinier finish often compared to a cloudy mirror. Stainless steel is polished by mills in a range of forms e g. Sheet plate bar tube but all finishes may not be available on all forms.

It resembles a very hazy mirror with some reflection evident. This surface which is found on thicker sheets and plate is slightly coarse with very low reflectivity. 316 stainless sheet is widely used in marine and highly acidic environments underwater equipment surgical tools food and pharmaceutical applications the addition of molybdenum increases the corrosion resistance of 316 stainless over the more economical 304 grade. 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.

It is especially common in industrial chemical and food processing applications such as process vessels and tanks. 316 316l stainless steel sheet is a popular grade of stainless where superior corrosion resistance is of primary importance. 304 stainless steel 2b finish is a mill finish which is smooth and not the brushed finish commonly seen on kitchen appliances. 2b can be more easily polished to a high luster than a no.

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 is important therefore to check that the finish is available in the form required. 304 stainless steel 2b finish is light gray in color. Considered the most widely used surface finish 2b is the basis for most polished and brushed finishes.

It is obtained by a final light roll pass of the sheet through polished rolls.
