Stainless Steel Sheet Finish Types

Type 316 is a high corrosion resistance alloy providing greater resistance to pitting type corrosion.

Stainless steel sheet finish types.

Great care should be taken in removing the surface defects in the metal like pits that could allow bacteria to grow. Such common stainless steel grades as 201 304 304l and 316l come in a standard 2b finish. This type of stainless sheet thickness provides excellent corrosion resistance for both industrial and marine applications. The cold rolling produces a smoother less pitted surface.

Type 304 can be easily roll formed or bent and its excellent corrosion resistance and weldability make it one of the most popular grades. 2d this finish is also achieved by cold rolling heat treating and pickling but unlike 2b does not receive the light rolling. The 304 stainless steel sheet 4 finish has a pvc film on one side to help protect against scratching during fabrication and installation. Each formulation of stainless steel alloy has its own unique properties for tensile strength melting point oxidation resistance and corrosion resistance.

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. Here s a brief round up of 10 types of stainless steel surface finishes. Surface imperfections are sometimes erased by grinding which can leave behind shiny spots. Next it is softened and de scaled in acid solution.

This finish is produced by polishing with a 180 240 grit belt. This finish is mainly used for industrial applications such as furnace arch supports furnace conveyors furnace linings air heaters boiler baffles incinerators kiln liners and industrial oven liners among. Picking the right grade of stainless steel requires knowing what your options are. It is obtained by a final light roll pass of the sheet through polished rolls.

This surface which is found on thicker sheets and plate is slightly coarse with very low reflectivity. Considered the most widely used surface finish 2b is the basis for most polished and brushed finishes. It resembles a very hazy mirror with some reflection evident. Ryerson stocks many varieties of stainless steel sheet including 304 stainless steel the most popular of the stainless steels.

There are countless variations of stainless steel that you could potentially use for a custom wire basket or tray. 304 stainless steel sheet 4 finish is the brushed finish commonly seen on kitchen appliances and backsplashes. Our 304 stainless steel sheet 4 finish meets the criteria for both the 3 and 4 finish. It is primarily used for non decorative purposes.

Stainless steel sheet is available in type 304 and type 316. A bright cold rolled finish is the most commonly mill finish for light gauge stainless steel sheet. 2b matte finishes are the least expensive of the stainless steel finishing options. 1 finish has a dull rough uneven appearance.

4 dairy or sanitary finish this finish is commonly used for the medical and food industry almost exclusively used on stainless steel. The finish is produced by cold rolling stainless steel through special rolls or dies.
