abs steels are types of structural steel which are standardized by the american bureau of shipping for use in shipbuilding 1 abs steels include many grades in ordinary strength and two levels of higher strength specifications all of these steels have been engineered to be optimal long lived shipbuilding steels abs does permit the use of other steels in shipbuilding but discourages it and requires more detailed engineering analysis basic properties edit all abs steels are standard carbon steels as with other grades of steel they have a specific gravity of 7 8 citation needed material
