NV E690 shipbuilding steel plate is an extra higher strength shipbuilding plate which is mainly used for built hull of vessels,ship body construction and oil offshaore platform.Normally when rolling,quenched and tempered would improve steel strength in yield and tensile points.Generally before using these ship plates DNV Grade E690,steel plate pretreatment is necessary.Pre-treatment including shot blasting and painting with shop primer.
