What causes the rust phenomenon of API 5L L485 PSL1 steel material

Our quality control department will do inspection for details of the steel materials API 5L L485 PSL1 steel material 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.
