marine steel grades AH36, DH36, EH36 and FH36 have same chemical composition and tensile requirement. So what are the differences among Grades AH36, DH36, EH36 and FH36. Do you have any idea?
Marine steel grades AH36, DH36, EH36 and FH36 all are higher strength structural shipbuilding steel. The main difference among Grades AH36, DH36, EH36 and FH36 is the impact temperature.
The test temperature of Grade AH36 Shipbuilding Steel plate in Charp V-notch impact requirements is 0°C.
The test temperature of Grade DH36 shipbuilding steel plate in Charp V-notch impact requirements is -20°C.
The test temperature of Grade EH36 shipbuilding steel plate in Charp V-notch impact requirements is -40°C.
The test temperature of Grade FH36 shipbuilding steel plate in Charp V-notch impact requirements is -60°C.
The 36 series marine steel plates have high strength, tensile strength 490-630MPa. The yield strength is 355MPa.
Grades AH36, DH36, EH36 and FH36 steel plates can be produced by national classification societies: ABS, BV, CCS, DNV, GL, KR, LR, NK, RINA. Our certified ABS-AH36, BV AH36, CCS-AH36, DNV-AH36, GL-AH36, KR -AH36, LR-AH36, NK-AH36, RINA-AH36 shipbuilding steel are all available in October.
