低合金高强度钢板广泛用于制造厂房、一般建筑及各类工程机械,如矿山和各类工程施工用的钻机、电铲、电动轮翻斗车、矿用汽车、挖掘机、装载机、推土机、工业鼓风机、各类起重机、煤矿液压支架等机械设备,如今社会又是工业化发展,所以成就了低合金高强度钢板。低合金高强度钢板的特性：

High strength low alloy steel plate is widely used in the manufacturing workshop, general construction and all kinds of engineering machinery, such as various types of mines and construction projects for the drilling rig, excavator, electric wheel dump truck, truck, excavators, loaders, bulldozers, industrial blowers, all types of cranes, hydraulic support of coal mine machinery equipment, now the society is industrialized. So the achievements of high strength low alloy steel plate. Characteristics of low alloy and high strength steel plate:

(1)高强度:一般其的屈服强度在300MPa以上。

(1) high strength: generally its yield strength is above 300MPa.

(2)高韧性:要求延伸率为15%~20%,室温冲击韧性大于600kJ/m~800kJ/m. 对于大型焊接构件,还要求有较高的断裂韧性。

(2) high toughness: the requirement of extensibility is 15%~20%, and the impact toughness at room temperature is greater than 600kJ/m~800kJ/m. for large welded components, and higher fracture toughness is required.

(3)良好的焊接性能和冷成型性能。

(3) good welding performance and cold forming performance.

(4)低的冷脆转变温度。

(4) low cold brittle transition temperature.

(5)良好的耐蚀性。

(5) good corrosion resistance.
