P460NL1 -- high-strength normalized pressure vessel steel. Re>=460 MPa. For offshore process vessels, LNG storage and high-pressure chemical plant requiring high-strength weldable steel to -50 C.
P460NL1 per EN 10028-3 (1.8916). Fine-grain normalized HSLA steel with guaranteed impact properties at -50 C (NL1 sub-grade). Re>=460 MPa with good weldability (CE~0.43). Standard for offshore process vessel shells, LNG storage vessel inner tanks and chemical plant pressure vessels at low temperatures where P355GH/P265GH are insufficient in strength and standard S460N lacks pressure vessel qualification.
