Shipyards use shipbuilding steel plate NK Grade AH40 to construct tanks and vessels in ships cause NK Grade AH40 ship plate owned the higher yield strength and tensile strength. Xinsteel group owned tens of stock warehouses in port cities in China,there are thousands tons of shipbuilding steel plate and sheet and angles and buld flats in stock which are ready to ship on board.Different thicknesses,width mainly in 2000-2500mm,length mainly in 6000-12000mm for steel plate NK Grade AH40.
Our normal rolling period for ship plate NK Grade AH40 shall be about 15 days for hundreds tons,and then NK agency would come to our mill for sample inspection before shipment,and finally our mill issue the mill test certificates for each plate and NK agency stamped and endorsed on our Mill test certificates.So this systerm can gurantee all our plates are properity and quality.Else,our mill had cooperated with other eight classification societies,such as ABS,LR,GL,DNV,BV,CCS,RINA,KR.
