The higher quality EN10025-4 S275ML steel supplier manufacturer

EN10025-4 S275ML steel supplier seamless pipe belongs to high strength medium carbon steel, with certain plasticity and toughness, high strength and good machinability. Good comprehensive mechanical properties can be obtained by quenching and tempering treatment. In addition, the hardenability of 45# seamless pipe is poor, and the water quenching is easy to produce cracks. After quenching and tempering, the small and medium-sized parts can obtain better toughness and higher hardness. For large parts (the section size is more than 80mm), normalizing treatment is appropriate. But the weldability of No.45 steel is poor. The weldment should be preheated before welding and annealed after welding to eliminate welding stress.

EN10025-4 S275ML steel supplier and so on medium and heavy plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on fields. The surface quality problems of medium and heavy plates not only affect the appearance of the products, but also reduce the corrosion resistance, wear resistance, fatigue limit and other properties of the steel plate. Therefore, the medium and heavy plates manufacturers and users attach great importance to it. The surface quality of medium and heavy plate mainly refers to the surface smoothness, surface defects, etc., which is one of the main quality indexes of medium and heavy plates.
