Stainless Steel Sheet Finish Types

There are countless variations of stainless steel that you could potentially use for a custom wire basket or tray.

Stainless steel sheet finish types. Picking the right grade of stainless steel requires knowing what your options are. 30 ra 20 ra. 2b matte finishes are the least expensive of the stainless steel finishing options. It resembles a very hazy mirror with some reflection evident.

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. 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. 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.

Our 304 stainless steel sheet 4 finish meets the criteria for both the 3 and 4 finish. It is obtained by a final light roll pass of the sheet through polished rolls. Here s a brief round up of 10 types of stainless steel surface finishes. This surface which is found on thicker sheets and plate is slightly coarse with very low reflectivity.

304 stainless steel sheet 4 finish is the brushed finish commonly seen on kitchen appliances and backsplashes. Surface imperfections are sometimes erased by grinding which can leave behind shiny spots. Great care should be taken in removing the surface defects in the metal like pits that could allow bacteria to grow. The finish is produced by cold rolling stainless steel through special rolls or dies.

Such common stainless steel grades as 201 304 304l and 316l come in a standard 2b finish. Ryerson stocks many varieties of stainless steel sheet including 304 stainless steel the most popular of the stainless steels. 4 dairy or sanitary finish this finish is commonly used for the medical and food industry almost exclusively used on stainless steel. Another popular grade is 316 stainless steel which is used in applications where additional corrosion resistance is required.

Next it is softened and de scaled in acid solution. The 304 stainless steel sheet 4 finish has a pvc film on one side to help protect against scratching during fabrication and installation. Type 316 is a high corrosion resistance alloy providing greater resistance to pitting type corrosion. This finish is produced by polishing with a 180 240 grit belt.

Stainless steel sheet is available in type 304 and type 316. There are a number of basic types of stainless steel finishes. It is primarily used for non decorative purposes. 2d this finish is also achieved by cold rolling heat treating and pickling but unlike 2b does not receive the light rolling.

Each formulation of stainless steel alloy has its own unique properties for tensile strength melting point oxidation resistance and corrosion resistance. Considered the most widely used surface finish 2b is the basis for most polished and brushed finishes.
