S550QL steel is a kind of excessive yield strength quenched and tempered structural metal materials. S550QL metal plates also have -forty diploma low temperature impact check. These requirements relate to the supply circumstances for alloy and non-alloy steels supplied in chilly rolled strips of as much as 600mm width for heat remedy The metal names in these requirements are allotted in accordance with BS EN and CR and the steel numbers are allotted in accordance with BS EN 10025-6.
Grade s235jr is a type of non-alloy metal, supposed for use for structural functions. This specific metal grade categorized in Part 2 of the Euronorm specification EN 10025. The letter capital S in the term EN S235JR Pipe signifies a structural steel that displays a minimum yield strength properties of round 235 MPa. On the other hand, the letters with a designation JR confirms that the supply has been administered a Charpy V-notch impact take a look at.
