Precautions for A572 grade 50 carbon steel plate sheet welding
Steel strip is a branch of steel plate. Steel strip is a kind of narrow and long steel plate, also known as strip steel, A572 grade 50 carbon steel plate sheet produced by various steel rolling enterprises to meet the needs of different industrial departments and industrial production of various metal or mechanical products. The width of steel strip is within 1300mm, and the length is slightly different according to the size of each roll. Generally, A572 grade 50 carbon steel plate sheet steel strip is supplied in coils, with the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. The steel strip is a kind of steel with large output, wide use and many varieties.
S690QL steel plate delivery status: quenched and tempered.Note: Quenching and then tempering directly after hot rolling is considered equivalent to conventional quenching and tempering.A572 grade 50 carbon steel plate sheet, S690QL steel plate characteristics:S690QL uses controlled rolling technology. It can be seen from the chemical composition of the steel that the content of harmful elements S and P is relatively low, indicating that S690QL steel is pure and has good welding performance.
Our quality control department will do inspection for details of the steel materials A572 grade 50 carbon steel plate sheet 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.
How to distinguish the inferior steel plate? 1. The surface of the fake and inferior steel plate is easy to produce scab. 2. The material of fake and inferior steel plate is not uniform and there are many impurities. The surface of fake and inferior steel plate is often pitted. Pitting is an irregular and uneven defect on the surface of A572 grade 50 carbon steel plate sheet, steel plate caused by serious wear of rolling groove. Due to the pursuit of profit by the manufacturers of fake and inferior steel plates, the groove rolling often exceeds the standard.
