The business department is mainly responsible for communicating with customers, from the manufacturing of steel plates, steel pipes and other products, knowing customers' needs and processing conditions, etc. within the time agreed with customers, the delivery time is short, the price is the most competitive, and the service is the best. Their responsibilities are to deal with customer consultation, solve customer problems, update production plans, and instruct the logistics department to deliver products to customers.yield strength of NM400 wear resistance
, European standard high strength EN10025-6 S690QL steel plates are mainly used for manufacturing construction machinery, mining machinery, all kinds of engineering machinery, such as the drilling rig, the electric shovel, the electric wheel dump, the mine motor, the excavator, and the loader for all kinds of engineering construction., etc.
Yield strength of NM400 wear resistance,The carbon content of medium carbon steel plate is 0.25% - 0.60%. In addition to carbon, it can also contain a small amount of manganese (0.70% - 1.20%). The medium carbon steel plate after quenching and tempering has good comprehensive mechanical properties. The highest hardness is about HRC55 (hb538) and σ B is 600-1100mpa.
Bridge steel plate is specially used for erecting railway or highway bridges. , bridge steel plate is required to have high strength and toughness to bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance The bridge steel plate used for bolt welding bridge should also have good welding performance and low notch sensitivity,yield strength of NM400 wear resistance.
