High strength A131 Grade AH40 steel plate and A131 Grade AH36 steel plate

High strength steel materials A131 Grade AH40 steel plate and A131 Grade AH36 steel plate are mainly used for ship buildings and oil platform buildings.A131 Grade AH40 takes minimum 390 Mpa yield strength and tensile strength within 510-650Mpa,however,A131 Grade AH36 steel plate takes minimum 355 Mpa yield strength and tensile strength above 490 Mpa.For direct usage in shipyard,Xinsteel industrial offer A131 Grade AH36 steel pate and A131 Grade AH40 steel plate with shot basting and painting with prime.The prime treatment standard would follow customers’ requirements such as SA 2.5,SSPC.

ABS class certificate A131 Grade AH36 steel plate and A131 Grade AH40 steel plate stock in our warehouses,these shipbuilding steel plates would be along with EN 10204 3.2 ABS certificate,ABS officers stamped and signed on our oringial mill certificates after inspection.
