It is typically noted that steel components produced using English standards are available with certain designations. For instance, components manufactured from grade S355JO chronicles several aspects via the letter S, the term JO as well as the number 355. Firstly, the term S is an indication that the EN 10025 S355JO Steel Plate is structural steel. The alloy is preferred across multiple industrial sectors because not only can it be readily surface treated, but the tests conducted on the EN 10025 S355JO Pipe is done by using the most accurately calibrated and latest technology.
Speaking of tests, EN 10025 is a standard that takes into account impact testing at various temperatures. Which brings us to the term JO. Basically, the specified EN 10025 S355JO material is impact tested at 0 °C. However, if the grade were termed as JR or J2, the impact tests were to be conducted at either 20 °C or -20 °C respectively. Lastly, the numerical value is a testament of its minimum yield strength, which in this instance is 355 N/mm² and is highly valued by engineers across all fields. Along with good cold forming properties, this fully killed EN 10025-2 S355J0 high strength structural steel plate has no porosity, and no free gaseous molecules present on its surface. The absence of both which drastically reduces corrosion in these products. Hence, the performance, as well as the longevity of EN 10025-2 Grade S355J0 / 1.0553 Steel Plates in combination with high tensile strength, makes them an investment, particularly in industries involving construction. The machinability of S355JO Structural and Offshore Steel Plates is similar to mild steels and they also demonstrate superior weldability along with good impact resistance.
