Stainless steel sheet mill finish.

316 316l stainless steel sheet is a popular grade of stainless where superior corrosion resistance is of primary importance. Annealing consists of heating the steel and letting it cool down slowly to remove internal stress and reduce hardness. 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. 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.

Also known as duplex stainless steel it has twice the strength of 316 stainless steel. Use it for high pressure applications in caustic environments. Our 430 stainless steel sheet metal meets the criteria for both the 3 and 4 finish. Stainless steel sheet mill finish is a dull grey finish.

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. Stainless steel with a 2b finish is generally used for bakeware and flatware plumbing fixtures solar panels industrial equipment and wheel covers. Let s review two of the more common mill finishes. Whether we are talking hot rolled or cold rolled all stainless steel flat products are treated with a standard mill finish.

The reverse side of the sheet is not controlled and because of the nature of the production process is. 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. 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. 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.

430 stainless steel sheet 4 finish has a pvc film on one side to help protect against scratching during fabrication and installation. It has become popular in kitchens due to its low maintenance cleanliness appearance and corrosion resistance to food acids and water. 2205 stainless steel resists cracking even when faced with a combination of tensile stress corrosive chemicals and heat. 430 stainless steel sheet 4 finish is the brushed finish commonly seen on kitchen appliances and backsplashes.

This surface which is found on thicker sheets and plate is slightly coarse with very low reflectivity. It is primarily used for non decorative purposes.
