Composition of Corten Steel

As a low carbon steel, corten steel usually has less than 0.3% carbon by weight. This small
amount of carbon keeps it tough and tough. Weatherproof steel also includes other alloying
elements, which help to improve strength, but more importantly, corrosion resistance. Many
different alloying elements are used, but the three key elements in weathering steel are nickel,
copper and chromium.

Classification of Corten Steel

Corten steel is a series of low carbon alloy steel, which is composed of many brands. Certain
grades are proprietary, such as COR-TEN A or COR-TEN B.Patinax weathering steels, which are
another group of proprietary grades. All these proprietary levels are similar to ASTM
classifications A 242 and A 588.
