S690QL1 american equivalent, Q345B low alloy plate performance:
1) High strength: Generally its yield strength is above 300MPa;
2) High toughness: The elongation is required to be 15% to 20%, and the room temperature impact toughness is greater than 600kJ/m to 800kJ/m. For large welded components, higher fracture toughness is also required;
3) Good welding performance and cold forming performance;
4) Low cold brittle transition temperature;
5) Good corrosion resistance.

As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's S690QL1 american equivalent steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole S690QL1 american equivalent steel transportation industry.

The alloy wear-resistant layer of S690QL1 american equivalent, wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is fibrous distribution, and the fiber direction is vertical to the surface. The alloy carbide has strong stability at high temperature, maintains high hardness, and has good oxidation resistance. It can be used normally within 500℃.
