Weathering Steel Plates Features and Projects
which is resistant to atmospheric corrosion steel
, is a series of low-alloy steels
between ordinary steel and stainless steel
. Weathering steel is made of ordinary carbon steel and a small amount of corrosion-resistant elements such as copper and nickel. It has the toughness and plasticity of high-quality steel. Characteristics such as extension, molding, welding, abrasion, high temperature and fatigue resistance; weather resistance is 2 to 8 times that of ordinary carbon steel, and coating performance is 1.5 to 10 times that of ordinary carbon steel. At the same time, it has the characteristics of rust resistance, anti-corrosion and life extension, thinning and reducing consumption, saving labor and energy. Weathering steel is mainly used for steel structures such as railways, vehicles, bridges, and towers that have been exposed to the atmosphere for a long time. It is used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms and containers containing hydrogen sulfide corrosion medium in chemical petroleum equipment.
It refers to a low-alloy structural steel with a protective rust layer that is resistant to atmospheric corrosion and can be used to manufacture steel structures such as vehicles, bridges, towers, and containers. Compared with plain carbon steel, weathering steel has better corrosion resistance in the atmosphere. Compared with stainless steel, weathering steel has only a small amount of alloying elements, such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium, etc., the total amount of alloying elements is only a few percent, not like stainless steel, reaching 100 More than a dozen, so the price is relatively low.
Weathering steel application
Weathering Steel Plate Projects
1. High-performance weathering steel and fire-resistant steel can reduce the maintenance cost of steel structure, and provide new solutions to solve the fire and corrosion problem of exposed unshielded steel structure, such as high-voltage electric tower.
2. the production and installation process of fire-resistant weathering steel is basically the same as that of conventional steel, and the design method is the same as ordinary steel structure, but more test verification is needed.
3. High-strength weathering steel has been promoted and applied in bridge engineering, and it is necessary to study design theory and method.
4. Fire resistant weathering steel can also be used in the floor board.
