Stainless steel refers to alloyed or unalloyed steels that contain at least 10.5% chromium and less than 1.2% carbon. Colloquially, stainless steel is also referred to as stainless steel (NiRo), although not all stainless steel is the same as "stainless".

The term plain indicates a completely untreated, merely oiled, smooth surface for all DIN and ISO screws such as wood screws, hexagon head screws, threaded rods, nuts and many types of washers.

The types of steel differ in their chemical composition, their areas of application and their resistance to corrosion. The most commonly used types of steel are A2 and A4 steels, whereas A1 is used less due to its lower corrosion resistance. The steel type A5 has its predecessor (A4) as the starting material, but is hardened by alloying elements such as titanium, niobium or tantalum and exhibits very good behavior against intergranular corrosion.
