P460NH pressure vessels steel plate, special low temperature pressure vessel steel plate, the implementation of standard EN10028-3:2003, instead of the old EN10028-3:1992 implementation standard, under this standard, the grade steel grade is divided into 4 quality levels:
1, room temperature quality grade (P460N)
2, high temperature quality grade (P460NH)
3, low temperature quality grade (P460NL1)
4. Special low temperature quality grade (P460NL2)
EN10028-3 P460NH pressure vessels steel plate chemical composition and mechanical properties are slightly, the relevant technical requirements can be agreed upon at the time of ordering and inquiry, if there is no special requirements (for example: high temperature drawing, carbon equivalent value CEV, elongation, flaw detection, steel plate sampling position, S/P limit, etc.), according to EN10028 standard.
The main grades of this steel grade are: P275NH, P355N, P355NH, P460NH, P275NL1, P355NL1, P460NL1, P355NL2, P275NL2, P460NL2.
