Grade S355 is a low carbon manganese-containing steel alloy. This medium tensile carbon steel possesses both good weldable properties as well as good impact resistance. Steel grade S355 is also well suited to be employed in sub-zero temperature applications. There are several designations allocated under specification EN 10210. For instance, the symbol J in combination with either numerical i.e. 0 or 2, would mean that the specific impact properties ofEN 10210 S355J2H Steel Pipeat specific temperature points of 0℃ and - 20℃ apiece.

The letter H is a designation intended for hollow sectioned products like theS355J2H Pipe. The other designation that touches the base with regards to its application is the letter S, which is a typical feature of structural steels. There are several reasons as to why theEN 10210 S355J2H Seamless Pipeexhibits good impact strength. Firstly, the chemistry of the carbon steel group contains manganese, which not only improves its strength but also improves the hardness properties of theS355J2H EN 10210 Pipes. Secondly, in comparison to regular pipes, hollow sections have thicker walls. A thicker cross-section also makesEN 10210 Grade S355J2H Hot Finished CHSsturdy and very durable.
