What is minimum yield strength of Q355NH steel distributor?

Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional Q355NH steel distributor production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of Q355NH steel distributor leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.

Q355NH steel distributor, No.45 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 No.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.

The yield strength of Q690D steel plate is 690 Mpa and the impact temperature is - 20℃. Q355NH steel distributor, Q690D steel plate has high strength, good plasticity and toughness, good weldability and good cold and hot performance. Q690D steel plate is mainly used to manufacture various large engineering structural components and construction machinery. Because of its high strength and good toughness, Q690D steel plate can reduce the self weight of components and meet the requirements of large-scale and lightweight engineering components and equipment under the condition of ensuring strength, stiffness and reliability.

The purpose of alloying Q345B steel is to use the interaction of alloy elements with iron and carbon and the effect on iron-carbon phase diagram and the heat treatment of steel to improve the structure and properties of steel. Interaction of alloying elements with iron and carbon: After alloying elements are added to steel, they mainly exist in steel in three forms. That is: forming a solid solution with iron; forming carbides with carbon; and possibly forming intermetallic compounds in high alloy steels, Q355NH steel distributor.

EN10025-6 S960QL structural steel plates are quenched and tempered high strength steel with yield strength of 590Mpa ~ 960MPa. Q355NH steel distributor, S960QL steel plates have technical requirement of flaw detection, Z15 Z35 thickness direction performance requirements, high strength and high toughness requirements and so on.
