Stainless Steel Sheet Finish Grades

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.

Stainless steel sheet finish grades.

2d this finish is also achieved by cold rolling heat treating and pickling but unlike 2b does not receive the light rolling. There are a number of basic types of stainless steel finishes. It has good malleability and applied in forming products. Stainless steel sheet is produced in many types of finishes due to the various uses and applications that stainless steel can be used in.

It can also be quickly hardened by machining. Such common stainless steel grades as 201 304 304l and 316l come in a standard 2b finish. Most watches that are made of stainless steel are made of this grade. 1 finish has a dull rough uneven appearance.

Rolex is an exception in that they use type 904l. This finish is commonly used for the medical and food industry almost exclusively used on stainless steel. 300 series stainless steel. 316 stainless is made up of at least 16 chromium and 10 nickel.

It is very smooth and less likely to harbour airborne contaminants and moisture compared to any other mill finishes. 2 molybdenum is also added to 316 stainless to increase its corrosion resistance. Grade 316 is most suited to outdoor and marine applications. 200 series stainless steel.

Here s a brief round up of 10 types of stainless steel surface finishes. 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. Grades of stainless steel the grades of metal most used in fabrication include 304 316 430. The resulting stainless steel finish is capable of reflecting clear images.

This easy to clean finish has a typical ra between 0 05 0 1 micrometers. Stainless steel sheet finishes. Stainless steel sheet can vary in grades and finishes all of which will affect the properties of the metal and so to fabricate highly precise durable components that use the material s advantages many factors need to be considered. Contain chrome nickel manganese belongs to austenitic stainless steel.

This finish is produced by polishing with a 180 240 grit belt. 18 10 stainless often corresponds to this grade. Surface imperfections are sometimes erased by grinding which can leave behind shiny spots. This surface which is found on thicker sheets and plate is slightly coarse with very low reflectivity.

Great care should be taken in removing the surface defects in the metal like pits that could allow bacteria to grow. Grade 316 offers the best corrosion resistance among standard stainless steel and is often refered to as marine grade. It has become popular in kitchens due to its low maintenance cleanliness appearance and corrosion resistance to food acids and water. Considered the most widely used surface finish 2b is the basis for most polished and brushed finishes.

Also referred to as a4 in accordance with international organization for standardization iso 3506.
