The company adopts the international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety management system, and has realized the comprehensive integration of the three systems In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group,A514 Gr Q quenched and tempered steel.
A514 Gr Q quenched and tempered steel,The capital letter H in S355J0H and S355J2H stands for ""Hollow section"", which respectively represents the pipe of S355J0 and S355J2.The Executive Standards of S355J0 steel and S355J2 steel are both EN 10025-2, the difference is that they have different temperature requirements for impact energy: S355J0 - impact energy at 0 ℃ is required to be ≥ 27J. S355J2: impact energy at - 20 ℃ is required to be ≥ 27J.
Pressure vessel plates are used to manufacture pressure vessel equipment in petrochemical, gas separation and gas storage and transportation equipment It is required to have sufficient strength and toughness, good welding performance and hot and cold processing performance The general heat treatment of Q345R plate is hot rolling, controlled rolling, normalizing The impact temperature is normal temperature, 0 ° C, -20,A514 Gr Q quenched and tempered steel.
A514 Gr Q quenched and tempered steel,Welding is mainly used for manufacturing metal structure parts, and also for manufacturing machine parts. The welding connection performance is good, and it is convenient to weld steel plates, profiles or castings and forgings according to the needs. At the same time, welding can also connect different shapes and sizes (plate thickness, pipe diameter) or even different materials, so as to reduce weight, save materials, optimize resources and other purposes. The welding structure has high rigidity, good integrity, and easy to ensure air tightness and water tightness, so it is especially suitable for manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).
A514 Gr Q quenched and tempered steel,P235GH steel material number under EN10028-2:2003 standard is 10345 This steel is a European pressure vessel steel P235GH Mechanical properties: Tensile strength σb (350 ~ 480 MPa); Yield strength σs(215 MPa min); Elongation ≥25%; Brinell hardness ≤105 ~ 140 P235GH steel chemical composition (mass fraction,%): ≤016 C; ≤035 Si; 060 ~ 120 Mn; ≤0025 P; ≤0010 S; ≤030 Cr; ≤030 Ni; ≤030 Cu; ≤008 Mo; ≤002 V; ≤002 Nb; ≤0012 N; ≤0020 Al; ≤003 Ti,A514 Gr Q quenched and tempered steel.
The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.A514 Gr Q quenched and tempered steel
