A517Gr.Q manufacturing process and delivery status
1. Smelting method: The molten steel must be vacuum treated.
2, the delivery status of the steel plate: hot rolling delivery, sample quenching and tempering treatment, and according to the sample issued material report.
At present, A517Gr.Q is less in stock and needs to be fixed. A517Gr.Q can be used up to 8-120mm thick and width up to 3900mm.
