Our quality control department will do inspection for details of the steel materials A588 Gr A structural steel plate before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.
SA517GrQ material is a high-strength quenched and tempered alloy steel plate, which belongs to the steel for offshore oil drilling racks. The upper limit of SA517GrQ steel plate thickness is 150mm, and the upper limit of rack steel is 177.8mm. BBN STEEL has opened up a new heat treatment process route for the 177.8mm thick offshore platform rack steel A517GrQ, and strives to improve the production capacity of this product.
The wear-resistant layer of A588 Gr A structural steel plate wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy A588 Gr A structural steel plate carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.
Non-destructive flaw detection of steel plates is a test method for inspecting the A588 Gr A structural steel plate surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used A588 Gr A structural steel plate steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.
Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar.
