Weathering Steel Plate

Weathering Steel Plate

Weathering-resistant structural steel plate, i.e., atmospheric corrosion-resistant steel plate, belongs to low alloy high-strength structural steel plate, which is categorized into high-weathering-resistant structural steel and weathering-resistant steel for welded structures according to its main characteristics.

Weathering steel, that is, atmospheric corrosion-resistant steel, is between ordinary steel and stainless steel series of low alloy steel, weathering plate from plain carbon steel to add a small amount of copper, nickel and other corrosion-resistant elements and become, weathering for the plain carbon steel 2 ~ 8 times, coating for the plain carbon steel 1.5 ~ 10 times.

Weathering steel with "Corrosion resistance" (Corrosion resistance) and "Tensile strength" (Tensile strength) for the abbreviation of the trade name "COR-TEN" is the most well-known. "The most well-known, so the English often "Corten Steel" instead of weathering steel. Unlike stainless steel, which does not rust at all, weathering steel only oxidizes on the surface and does not oxidize deep inside, and has corrosion-resistant characteristics like copper or aluminum.

Corten steel sheet is generally used in concentrate into the furnace - smelting (converter, electric furnace - micro-alloying treatment - blowing argon - LF refining - low-superheat continuous casting (feeding rare earth wire) - controlled rolling and cooling and other process routes. In the smelting, scrap with the charge together with the furnace, smelting according to the conventional process, after the steel to add deoxidizer and alloy, steel by blowing argon treatment, followed by casting, blowing argon tempering steel cast into slabs by continuous casting machine. Due to the addition of rare earth elements to the steel, weathering steel plate is purified, the content of inclusions is greatly reduced.

Weathering-resistant steel is mainly used for steel structures used in railroads, vehicles, bridges, pylons, photovoltaic, high-speed engineering and other long-term exposure to the atmosphere. It can also be used to manufacture structural parts such as containers, railway vehicles, oil derricks, harbor buildings, oil extraction platforms and containers for sulfur-containing corrosive media in chemical and petroleum equipment. In addition, due to the unique appearance of weathering steel, it is also often used for public art, outdoor sculpture and building facade decoration.
