Weathering steel (Corten steel)
has been continuously developed and innovated after incorporating modern metallurgical new mechanisms, new technologies and new processes, and is widely used in weathering steel landscaping
. It belongs to one of the series of steels of the world's leading level of super steel technology.
Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of toughness, plastic extension, forming, welding, abrasion, high temperature, fatigue, etc. of high-quality steel. 8 times, the coating is 1.5-10 times that of ordinary carbon steel, which can be used thinner, bare or simplified.
The weathering steel has the characteristics of rust resistance, corrosion resistance and life extension, thinning and consumption reduction, labor saving and energy saving, which benefit the component manufacturers and users. Weathering steel products are used to manufacture structural components such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, and containers containing hydrogen sulfide corrosive media in chemical and petroleum equipment.
The specific role of weathering steel is as follows:
1. High-performance weathering steel and refractory steel can reduce the maintenance cost of steel structures, and provide a new solution to the problem of fire protection and corrosion protection of exposed and unprotected steel structures, such as high-voltage electrical towers.
2. The manufacturing and installation process of fire-resistant and weather-resistant steel is basically the same as that of conventional steel, and the design method is also the same as that of ordinary steel structure, but more tests are required for verification.
3. High-strength weathering steel has been widely used in bridge engineering, and design theory and methods need to be researched.
4, fire-resistant and weather-resistant steel can also be used for floor plates.
