Chinese famous manufacturer and supplier of S550QL1 EN 10025-6 high strength steel

Material common grades: Q235B,Q345B, AB EH32, AB DH36, AB EH36, S550QL1 EN 10025-6 high strength steel, CCS-A, CCS-B,CCSA, CCSB, CCS,CCSD, CCSE. Carbon structural steel plates and sheets are mainly used in the manufacturing of mechanical parts with complex shapes and high requirements for mechanical properties, but it is difficult to shape them by forging and pressing in the process, such as the gearbox shell of the automobile, the coupler and coupling of the locomotive and vehicle.

Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, S550QL1 EN 10025-6 high strength steel quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the S550QL1 EN 10025-6 high strength steel International leading steel materials supplier.

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 S550QL1 EN 10025-6 high strength steel 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 S550QL1 EN 10025-6 high strength steel steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.

Chromium element (Cr element) can improve the strength and hardness of S550QL1 EN 10025-6 high strength steel, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.

The company's after-sales service tenet is "customer first, timely guarantee, enthusiastic service and effective work". In order to establish a set of perfect after-sales service system and strict management system, so that the after-sales service can be effectively guaranteed. The company has set up after-sales service department to ensure timely, unique and effective response to every user's request, coordinate internal resources internally, and put an end to all evasion and delay.
