Surfaces

In principle the surface of stainless steel sheets is shiny metallic. Depending on manufacturing the state varies. Hot-rolled products have a rougher surface than cold-rolled products. The surface treatment can be important for the corrosion resistance. You can find an overview of the possible versions according to DIN EN 10088 on this homepage.

The stainless steel finishes consist of an alphanumeric abbreviation. The number 1 represents hot-rolled products and the number 2 represents cold-rolled products.

Commercial standard finishes are e.g.:

1D – (hot-formed, heat-treated, pickled – free from scaling)

2B – (cold-rolled, heat-treated, pickled, cold rerolled)
