Weathering steel plate for welding structure is made by adding metal materials such as chromium, molybdenum, titanium and vanadium to ordinary molten steel. The addition of these materials can form a protective film on the steel surface, which can resist weathering corrosion for a long time. The advantages of weathering steel plate for welding structure: It has very good welding performance and weather resistance, and is widely used in railways, bridges and other areas that need to be exposed to the atmosphere for a long time. Disadvantages of weathering steel plate for welded structure: It has very high requirements on the production process, and the poorer technology can not produce good weathering steel plate, astm a242 atmospheric corrosion resistant steel.
In the process of astm a242 atmospheric corrosion resistant steel steel transportation, enterprises often use railway transportation, highway transportation, water transportation and other ways to transport. According to the cargo owner's requirements on the timeliness of the goods and the different transportation routes, our company will choose astm a242 atmospheric corrosion resistant steel different modes of transportation. According to the specific needs of customers, or specify the mode of transportation.
astm a242 atmospheric corrosion resistant steel Weldability refers to the performance of the weld joint with the expected quality requirements obtained by common welding methods under specific structure and process conditions. Weldability is generally judged by the crack sensitivity and the change of mechanical properties of weld zone. The ability of steel materials to withstand bending without cracking at room temperature is called cold bending. The greater the bending capacity before crack, the better the cold bending performance of the steel material.
