ASTM A514 Grade Q Boiler steel plate application :
A514 GrQ steel which has good weldability, often used in offshore drilling platforms gear, rack steel. In the course of their work offshore drilling platform, the gear - rack mechanism responsible elevating work across platforms. Therefore, in the construction of offshore platforms, rack welded and precision control has occupied a very important position.
