N, Q); the elevated temperature quality (P . NH, QH); the low temperature quality (P . NL1, QL, QL1); the special low temperature quality (P . NL2, QL2).5.1.2In accordance with the classification system in EN 10020, the steel grades P275NL1, P355N,P355NH and P355NL1 are classified as alloy quality steels and the other steel grades are classified as alloyspecial steels.5.2 Designation5.2.1For the tubes covered by this Part of EN 10216 steel the designation consists of: the number of this Part of EN 10216;plus either: the steel name in accordance with EN 10027-1 and CR 10260;or : the steel number allocated in accordance with EN 10027-2.5.2.2The steel name is designated by: the capital letter P for pressure purposes; the indication of the specified minimum yield strength for the lowest applicable wall thickness groupexpressed in megapascals, (Table 4); one of the additional symbols N, NH, NL1, NL2, Q, QH, QL, QL1 or QL2 (see 5.1.1, Tables 2 and 4).SIST EN 10216-3:2003
