Alloy steel is divided into low alloy steel, medium alloy steel, and high alloy steel. As the name suggests, it is distinguished by the total amount of alloy elements. If the total amount is less than 3.5%, it is called low alloy steel, 5 ~ 10% is medium alloy steel, and more than 10% is high alloy steel. In China, it is customary to call special quality carbon steel and alloy steel special steel. Low alloy structural steel plate is made of low alloy structural steel by hot rolling. Low alloy steel plates are killed and semi-killed steel plates. The utility model has the advantages of high strength, better performance, saving a large amount of steel, reducing the weight of the structure, etc.
1.High strength;
2.Good welding performance and cold forming performance;
3.Low cold brittle transition temperature;
4.Good corrosion resistance
It is mainly used for manufacturing bridges, ships, vehicles, boilers, high-pressure vessels, oil and gas pipelines, large steel structures, etc
