ASTM A242. ASTM A242 is a high strength low-alloy structural steel specification with improved atmospheric corrosion resistance. This specification is normally applicable to steel plates through one-half inch in thickness. The atmospheric corrosion resistance of A242 is substantially better than that of carbon steels such as A36 and A572-50 with or without copper addition.ATMOSPHERIC CORROSION DATA OF WEATHERING to USS CorTen B steel. This steel possesses less resistance to atmospheric corrosion due to its lower P content, but for this same reason it has better weldability.

Overall,Corrosion Protection American Galvanizers AssociationSteel is an abundant, efficient building material that provides specifiers design freedom. However, for projects exposed to the atmosphere and other harsh environments, it is critical to coat the steel for corrosion protection. Often large construction projects target a 50-100 year design life, highlighting the need for durable, long lasting corrosion protection.Corrosion Protection of Steel Structuresto carbon steel can reduce the rate of rusting to a greater extent. The elements Cu, P, Cr and Ni have all been shown to improve resistance to atmospheric corrosion. Formation of a dense, tightly adhering rust scale is responsible in lowering the corrosion rate leading to use without protection and can also extend paint life by
Type 316L has its corrosion resistance improved by adding molybdenum and reducing carbon. Type 316L is the most popular form of stainless steel used in medical application due to its high corrosion resistance.

For bare steel applications, when the weld is required to have strength, corrosion resistance and weathered appearance similar to that of the base metal, special electrodes must be used. When matching strength is required, and color match and corrosion resistance are not important, E70, E80, E90, E100 or E110 low-hydrogen electrodes may be used.Weathering steel - SteelConstructionfoWeathering steel is a high strength low alloy steel that was originally developed by United States Steel in the 1930s to resist corrosion and abrasion in their ore wagons.
