Mandatory for all steel work in P&G / mandatory for taxis in Germany since 1971, although in limited states only in recent years. RAL 1016: Sulfur yellow: Standard European ambulance colour in accordance with CEN 1789. [2] RAL 1017: Saffron yellow: RAL 1018: Zinc yellow: RAL 1019: Grey beige: RAL 1020: Olive yellow: RAL 1021: Colza yellow
In order to clearly distinguish the steel grade, tubing, casing and its coupling should be painted with color codes respectively. Color bands should be painted on tubing and casing body longer than 600mm to either end. The whole outer-body of the coupling needs to be painted color and then color codes
Chemical coloring of metals is the process of changing the color of metal surfaces with different chemical solutions. The chemical coloring of metals can be split into three types: electroplating – coating the metal surface with another metal using electrolysis. patination – chemically reacting the metal surface to form a colored oxide or ...
Steel that has been heated above its upper critical temperature and then cooled in standing air is called normalized steel. Normalized steel consists of pearlite, martensite, and sometimes bainite grains, mixed together within the microstructure. This produces steel that is much stronger than full-annealed steel, and much tougher than tempered ...

Electrochemical coloring of metals is a process in which the surface color of metal is changed by electrochemical techniques, i.e. cathodic or anodic polarization. The first method of electrochemical coloring of metals are certainly Nobili's colored rings, discovered by Leopoldo Nobili , an Italian physicist in 1826.
Steel blue is a shade of blue color that resembles blue steel, i.e., steel which has been subjected to bluing for protection from rust. It is one of the less vibrant shades of blue, and is usually identified as a blue-gray color. The first recorded use of steel blue as a color name in English was in 1817. [2] Blue steel
The SAE steel grades system is a standard alloy numbering system (SAE J1086 – Numbering Metals and Alloys) for steel grades maintained by SAE International. In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.
