For plates the thickness limitations are: S355G2+N, S355G5+M, - up to and including 20 mm S355G3+N, S355G6+M - up to and including 40 mm S355G7+N, S355G8+N, S355G9+N, S355G10+N - up to and including 150 mm S355G7+M, S355G8+M up to and including 100 mm S420G1+Q, S420G1+M, S420G2+Q, S420G2+M - up to and including 100 mm S460G1+Q, S460G1+M, S460G2+Q, S460G2+M - up to and including 100 mm.
One person familiar with the situation said Germany's ailing ThyssenKrupp Group was in talks with its international counterparts to merge its loss making ASTM A242 weathering steel plate steel business. The talks will be announced Monday as part of a strategic reform that could include closing or selling assets. Previously, ThyssenKrupp steel Europe, Germany's largest steelmaker, announced a loss in the first half of the group three point seven two 100 million euros four point zero two Billion US dollars). ThyssenKrupp has continued to advocate the benefits of ASTM A242 weathering steel plate steel integration since it abandoned its joint venture with Tata Steel a year ago to sell its precious elevator division.
After adding a small amount of niobium, vanadium and titanium to ASTM A242 weathering steel plate etc. steel, it is combined with the controlled rolling process to control the precipitation behavior of microalloying elements to achieve the purpose of improving the comprehensive properties of the steel, whether it is strength, toughness, ductile-brittle transition temperature, or Steel's process formability, welding performance, corrosion resistance and crack resistance have been significantly improved, while reducing production costs. Such steel products are widely used in oil and gas pipelines, vehicles, building structures, oil production platforms, pressure vessels, ship shells and many other fields.
This 2800-passenger cruise-type ro-ro passenger ship will be one of the most adaptable to climate change and one of the most intelligent and environmentally friendly ships. Compared with its smaller sister ship "Viking Grace", fuel consumption will be reduced by 10%. The ship cost 194 million euros, has a length of 218 meters, 13 decks, a lane length of 1,500 meters, and a maximum speed of 22.1 knots.
