低合金高強度鋼板廣泛用于制造廠房、一般建筑及各類工程機械,如礦山和各類工程施工用的鉆機、電鏟、電動輪翻斗車、礦用汽車、挖掘機、裝載機、推土機、工業鼓風機、各類起重機、煤礦液壓支架等機械設備,如今社會又是工業化發展,所以成就了低合金高強度鋼板。低合金高強度鋼板的特性：

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)高強度:一般其的屈服強度在300MPa以上。

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

(2)高韌性:要求延伸率為15%~20%,室溫沖擊韌性大于600kJ/m~800kJ/m. 對于大型焊接構件,還要求有較高的斷裂韌性。

(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)低的冷脆轉變溫度。

(4) low cold brittle transition temperature.

(5)良好的耐蝕性。

(5) good corrosion resistance.
