Requirements for chemical composition of SA633 Gr D carbon steel plate sheet

Every customer who has visit us and witness the steel materials before delievry will be impressed by our quality control departemnt. Even not come to inspect the steel materials before delievry, our quality control departemnt will also send inspection report to the customer. For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.Pipeline steel plate API 5L Gr.B, SA633 Gr D carbon steel plate sheet, X42, X46, X52, X56, X60, X65, X70, X80 is a key steel material for manufacturing straight-seam submerged arc welded pipe for high-pressure long-distance natural gas pipeline. X80 pipeline steel is currently the highest-grade pipeline steel in engineering application in the world. The our company produced X80 pipeline steel plates are successfully used in natural gas pipeline project with the largest wall thickness and diameter.Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while SA633 Gr D carbon steel plate sheet steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of SA633 Gr D carbon steel plate sheet steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.EN 10025-2 steel includes S235 steel (S235JR, S235J0, S235J2), S275 steel (S275JR, S275J0, S275J2), S355 steel (S355JR, S355J0, S355J2, S355K2), S450 steel (S450J0). According to EN 10025-2, the thickness of S450J0 plate is within 3-150mm. The SA633 Gr D carbon steel plate sheet, S235 steel, S275 steel and S355 steel plate thickness is ≤250mm. However, the S235J2, S275J2, S355J2 and S355K2 plates limitation is ≤400mm.The company has our own truck fleet, and can transfer products flexibly and quickly.
