Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of A514 grade P quenched and tempered steel circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and A514 grade P quenched and tempered steel management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.
According to different strength levels, the ASTM A516 plates are available in four grades: Grades 55, 60, 65, and 70. The most common is Grade 70 or called out A516-70. The maximum thickness of {keyword plates is limited only by the capacity of the composition to meet the specified mechanical property requirements. The mechanical properties such as tensile strength, yield strength, and elongation shall be determined by a tension test for the plates.
EN10083-3 27MnCrB5-2 steel plates usually need quenching and tempering are special application. Up to now, EN10083-3 27MnCrB5-2 steel plates are mainly applied in airplane, guided missile, weapons, railway, bridges, ships, vehicles, pressure vessel, machine tools, mechanical components with a bigger sectional size and so on fields.
The effect of nitrogen (N) on the properties of A514 grade P quenched and tempered steel and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in A514 grade P quenched and tempered steel and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
EN 10025-2 is standard for hot rolled products of structural steels. EN 10025-2 steel grades are A514 grade P quenched and tempered steel, S235JR, S235J0, S235J2 (S235 series); S275JR, S275J0, S275J2 (S275 series); S355JR, S355J0, S355J2, S355K2 (S355 series); and S450J0. The numbers 235, 275, 355, 450 indicates the min. yield strength for thickness ≤16mm. For example, when the thickness ≤16mm, the min. yield strength for S235 series steel is 235Mpa, S275 series steel is 275Mpa, S355 series steel is 355Mpa, and S450J0 steel is 450Mpa.
