The S355 steel material itself is divided into many grades, so it cannot be said that S355 is equivalent to which grade of the national standard Q345, EN10025-4 S275M steel. In engineering, usually S355JR steel is equivalent to Q345B steel, S355J0 steel is equivalent to Q345C steel, S355J2 steel is equivalent to Q345D steel, S355N steel is equivalent to Q345D steel, and S355NL steel is equivalent to Q345E steel.
20 to 26mm thick EN10025-4 S275M steel product BBN steel supply: 20*3000*5000, 20.5*2370*7000, 21*1960*7950, 22*1800*8000, 22*1500*6000, 22*1500*6050, 22.5*1680*8450, 22*1300*4000, 22*2600*9000, 22*1800*9000, 22.5*2560*7150, 23.5*2560*7150, 25*1460*4000, 23*3000*11980, 23*2480*8450, 23*2650*6000, 24*1560*6200, 25.5*2330*8300, 23*3000*12000, 23.5*2080*8100, 23*2650*6550, 26*3010*8100.
In October, steel production decreased month-on-month, port inventories continued to rise, iron ore demand intensity weakened slightly, and iron ore prices continued to fall. According to the monitoring of the China Iron and Steel Industry Association, at the end of October, the China Iron Ore Price Index (CIOPI) was 421.41 points, down 11.06 points month-on-month, or 2.56%. The month-on-month decline continued, with a decrease of 0.08 percentage points higher than in September.
EN10025-4 S275M steel plate weight: 1) Theoretical weight of EN10025-4 S275M steel plate: The theoretical weight of a steel plate is the weight calculated based on the nominal size and density of the steel plate (previously called specific gravity). It is closely related to the length, size, and cross-sectional area of the steel plate. 2) The actual weight of EN10025-4 S275M steel plate: The actual weight of the steel plate refers to the weight obtained through actual weighing, which is more accurate than the theoretical weight.
