Is Corten / Weathering Steel Eco Friendly?

1.What Is Corten /weathering Steel?

Corten/Weathering steel is a kind of steel that is resistant to oxidation, corrosion, wear and high temperature. Its main components are iron, carbon, silicon, manganese, chromium, nickel, molybdenum and other elements, which contain a large amount of chromium elements, which makes it have good corrosion resistance.

2.What Are The Characteristics Of corten/Weathering Steel?

Weathering steel is a special type of steel whose main feature is its ability to maintain long-term stable chemical and physical properties under harsh environmental conditions. Weathering steel is usually used for structural parts that need to be exposed to oxidation, corrosion, ultraviolet rays, acid rain and other environments for a long time. It has the characteristics of high strength, corrosion resistance, climate change resistance, heat resistance, weather resistance, good toughness, etc., and can be adapted to use in various extreme environments.

The main components of weathering steel are iron, chromium, nickel, silicon and other elements, of which chromium has the highest content, which can reach 10-12%. The main function of chromium is to prevent corrosion. In steel exposed to the air for a long time, chromium will produce a dense oxide layer, thereby preventing oxidation from further corroding the steel.

In addition to chromium, weathering steel also contains many other elements, such as cobalt, copper, vanadium, manganese, phosphorus, etc. The function of these elements is to increase the strength, toughness and plasticity of steel and provide better load capacity.

3.Is Corten/weathering Steel Eco Friendly?

• From the perspective of production, the production process of corten steel is relatively simple, and the components used are relatively common, so its production process is relatively environmentally friendly.

In some steel industries, the production of weathering steel is also seen as a more environmentally friendly production method.

• From the perspective of the use effect, the characteristics of weathering steel make it have superior corrosion resistance and oxidation resistance, which greatly reduces the maintenance and maintenance costs in its service life. At the same time, because it does not require additional anti-corrosion coatings, it reduces the pollution caused by the anti-corrosion process to the environment.

Therefore, from the perspective of the use effect, weathering steel can also be regarded as an environmentally friendly material.

• The recycling value of weathering steel is also worthy of affirmation. Even after use, the properties of weathering steel remain and can be reused in manufacturing.

Therefore, weathering steel can also be considered a sustainable material.
