Properties of Stainless Steel Alloys

There are more than 60 grades of stainless steel and over 150 grades of stainless steel finishes. Stainless steel alloy can be milled into; coils, sheets, plates, bars, wire & tubing.

Stainless Steel Grades

Stainless Steel Finishes

With over 150 grades of stainless steel finishes, the categories are basically standard and special.

“Standard” stainless steel finishes are categorized as either “Mill” or “Polished”. “Mill” finishes can be dull to mirror-like and are the least expensive of the finish options. “Polished” finishes can produce a mirror-like appearance. Surface finish designations like #4, #8 refer to the grit of the polishing media used to create the finish. "Mirror" finishes are sometimes called "super #8 or #10.

“Special” stainless steel finishes can include swirls, circles, embossing, coloring and other types of aesthetic requirements. A "Bright Annealed" finish is a highly reflective finish that is retained by final annealing in a controlled atmosphere furnace that does not affect the surface condition.
