Features and application of weather resistant steel

Weather resistant steel is a series of low-alloy steels located between ordinary steel and stainless steel. It is composed of ordinary carbon steel plus a little copper, nickel and other anti-corrosion elements, and has the characteristics of high-quality steel such as toughness, forming, abrasion, high temperature and fatigue resistance. .

The weather resistance is 2 to 8 times that of ordinary carbon steel, and the paintability is 1.5 to 10 times that of ordinary carbon steel. And it has the advantages of rust resistance, corrosion resistance, consumption reduction and energy saving of components.

Weather resistant steel is mainly used in steel structures that are exposed to the atmoSPHEre for a long time, such as railways, bridges and towers. It is used to make structural parts such as containers, oil derricks, oil production platforms and containers containing corrosive media in chemical and petroleum installations.

Features of weather resistant steel:

1. Rust and corrosion resistance, 4 to 8 times higher than ordinary steel in atmospheric corrosion resistance.

2. Materials can be recycled, very low-carbon and environmentally friendly

3. Steel parts have corrosion resistance, life extension, thinning, consumption reduction, labor saving and energy saving.

4. It is green and environmentally friendly, and does not require initial coating, which can reduce the use of fireproof materials and coatings, thereby reducing pollution, construction period, cost and maintenance.

Application of weather resistant steel

1. High-performance: weather resistant steel and refractory steel can reduce the maintenance cost of steel structures, and a new solution has been proposed to deal with the fire and corrosion phenomena of exposed unprotected steel structures, such as high-voltage electrical towers.

2. The manufacturing and installation steps of refractory and weather resistant steel are almost the same as those of conventional steel, and the design method should be the same as that of ordinary steel, but it must be verified by multiple tests.

3. High-strength: weather resistant steel has been popularized and used in bridges, so the design concept and method should be discussed.

4. Refractory: weather resistant steel can also be used for floor decks.
