. Ship course criteria D36, E36, grade F, EQ collection are primarily high toughness thick steel plate; ASTM A517 Q, A514 Q are often made use of for jack-up overseas system stacks; EN 10225 steel is extensively used in offshore structures as well as offshore wind power jobs. API 2W, 2Y, 2Z steels can be made use of to develop offshore systems. The thickness of these steel plates is 6mm up to 178mm, the yield toughness is 40KG ~ 70KG, the impact strength gets to -60 C high stamina thick plate steel, usually normalizing, TMCP, solidifying and other warm treatment procedures are needed to your specific requirements.
