Application areas | Steel for shipbuilding can be used for the entire range of shipbuilding applications e.g. for the hull and interior of ships | |
Chemical composition | For D grade, the carbon + 1/6 of the manganese content should not exceed 0.40%. The steel should contain aluminium, niobium, vanadium or other suitable grain-refining elements, either singly or in any combination. When these elements are used singly, the steel should contain the specified minimum content of the grain-refining element (0.02% ≤ Nb ≤ 0.05%, 0.05% ≤ V ≤ 0.10%, Ti ≤ 0.02%). When used in combination, the specified minimum content of each element is not applicable. | |
Delivery condtion | For the dimensions available please visit Dimension tables (see Table A). | |
Other | Agreements The maximum thickness approved in shipbuilding specifications can be communicated on request by your sales agent. Available options Options available (after prior agreement): Mechanical properties Charpy V notch impact test specimens should be taken in the longitudinal direction. Transverse test specimens are not usually required. Transverse test results for plates and wide flats should be guaranteed by the supplier. |
