Cold-forming high-strength steel for automobile beams and other structural parts: B510L, B320L, B420L, B510L, B510DL, B550L, B600L, B650L, B700L, B750L, S355MC, S420MC, S460MC, S500MC, S550MC,DD11, DD12, SPHC, SPHD, SPHE, QStE340TM, QStE380TM, QStE420TM, QStE460TM, QStE500TM automotive structural steel coil, QStE600TM, QStE650TM, QStE700TM (340XLF, ZSTE420, 410XLF) BR1500HS.

Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled q355nh weather resistant steel machinability products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the q355nh weather resistant steel machinability rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.

JIS g3101:2004 ss540 structural steel angle contains 0.30% carbon and 1.60% manganese, which greatly improves the strength of steel. Compared with q355nh weather resistant steel machinability SS400 and ss490, ss540 has higher strength with yield strength of 400MPa and tensile strength of 540Mpa. High strength makes it popular in applications that require strength but weight is a problem.

Accept the inquiry from the owner of the goods and the inquiry by sea: master the port and price from the port of shipment to all continents and routes, and the port and price that the owner often needs to serve; the shipping schedule information of the main shipping companies; when necessary, ask the owner of the inquiry for some category information, such as the name of the goods, the level of danger, etc. (water hazard code).

As leading EN10025-6 S460QL structural steel plates supplier in China, our company has supplied hundreds of thousands tons S460QL steel plates to clients to assist them finish one after another q355nh weather resistant steel machinability magnificent projects.
