It is reported that the technical requirements of P690QL2 ultra-high strength and low temperature steel developed this time are extremely strict, which are mainly reflected in three aspects: first, the strength level reaches the highest level of 690MPa in the global shipbuilding and marine steel standards; Second, the low temperature toughness reaches the highest quality grade of the global shipbuilding and marine engineering steel standard – 60 ℃; Third, the anti-cracking performance (CTOD performance) reached – 35 ℃, far lower than the existing international standard of – 10 ℃. In general, P690QL2 ultra-high strength and low temperature steel meets the safe and stable operation of cargo tanks under high pressure, low temperature and inertia loads.
