FH420 Low Temperature Performance Steel Plate FH420 Offshore Engineering Steel.
Introduction of FH420 low temperature performance steel plate, FH420 marine engineering steel.
FH420 steel plate is an ultra-high-strength steel plate for ship and offshore platform structure, and the low temperature resistance of the steel plate is also very good, and it can work in a low temperature environment of -60°C. CCS/ABS/NK/GLFH420 is a structural steel for ships and offshore engineering, which is divided into four quality grades: A, D, E, F, that is, AH420, DH420, EH420, FH420, H means high strength, and 420 is the lower yield strength of steel plate.

GB/T222 Wugang steel plate FH420 steel plate can produce different specifications of marine steel according to user needs, such as the United States, Norway, Japan, Germany, France, etc., and its classification society certification is as follows: China CCS USA ABS Germany GL France BV Norway DNV Japan NK United Kingdom LR Italy RINA South Korea's KR (Norway's DNV merged with Germany's: VL, certified by nine major classification societies. 8. FH420 steel plate flaw detection A and Z steel plates should be ultrasonic flaw detection, and the flaw detection grade should be indicated in the contract. Elongation: 19%
B, according to the requirements of the buyer, by the agreement of the supply and demand parties, other steel plates can also be non-destructively inspected. 9. AH420, DH420, EH420, FH420 ship plate practical application: AH420, DH420, EH420, FH420 ship plate is high-strength hull structural steel. Shipbuilding steel generally refers to the steel used for the hull structure, which refers to the steel used to make the hull structure produced according to the requirements of the production specifications of the classification society.
