800tons EN steel grade S235J0 plates exported to Thailand

Wear resistant steel plate EN steel grade S235J0 plates is an important material for industrial application. The traditional wear resistant steel is the high manganese steel which hardens under the impact load. The premise of its function must be subjected to enough impact load. With the development of wear resistant steel technology, NM series steel plate breaks through the limitation of traditional high manganese steel and realizes the application space of wear-resistant steel. The main EN steel grade S235J0 plates grades of NM series wear resistant steel plates are NM360, NM400, NM450, NM500, NM550, NM600.

With the development of China's EN steel grade S235J0 plates market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes group operation, intensive development and lean management, and builds the company into a company with scientific development concept, continuous innovation vitality, excellent corporate culture and strong sense of social responsibility through rich series of EN steel grade S235J0 plates products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the EN steel grade S235J0 plates quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After EN steel grade S235J0 plates quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.

After extrusion, the EN steel grade S235J0 plates tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.

The company conducts periodic and targeted training and guidance for after-sales service personnel. As the saying goes, "no one is perfect, no gold is red", to help after-sales service personnel improve service skills and correct service attitude. Carry out relevant technical training for after-sales service personnel, so that after-sales service practitioners have professional product knowledge.
