An aluminum hull structure, built to the same standards, weighs roughly 35% to 45% less than the same hull in steel. As a result, if high strength is of the highest priority, the alloy boat can be built to the same structural weight as the steel vessel, and then be considerably stronger.Approval of consumables for welding normal and higher nva hr ordinary strength hull structural- higher strength filler metals for welding normal and higher strength hull structural steels with minimum yield strength up to 390 N/mm2.
