8、WQ690D钢板运用：

8. Application of wq690d steel plate:

WQ690D可称为屈服强度690Mpa的耐低温高强钢，具有较高的屈服强度和抗拉强度，广泛运用于煤矿机械、工程机械，如液压支架、港口起重机、平板运输车。重型机械、海洋工程、金属结构等制造企业已联合舞钢协作出产WQ690D用于其企业出产建设项目中。

Wq690d can be called low temperature resistant high-strength steel with yield strength of 690mpa. It has high yield strength and tensile strength. It is widely used in coal mining machinery and engineering machinery, such as hydraulic support, port crane and flat transport vehicle. Manufacturing enterprises such as heavy machinery, offshore engineering and metal structure have cooperated with Wugang to produce wq690d for their enterprise production and construction projects.
