Introduction of 08Ni3DR steel plate:
08Ni3DR steel plate is a steel plate for ultra-low temperature container, which is specially developed to get rid of domestic long-term dependence on imports and meet the increasing domestic demand. 08Ni3DR steel plate is used to manufacture LNG storage tanks for storing and transporting liquefied natural gas and ultra-low temperature container steel plates for LNG ships. Among them, 08 means that the nominal carbon content in the steel plate is 0.08%, and Ni3 means that the nominal content of Ni in the steel plate is 3%.
Chemical composition of 08Ni3DR steel plate (melting analysis %):
| C | Si | Mn | P | S | Ni | Mo | V | Al |
| ≤0.10 | 0.15~0.35 | 0.30~0.80 | ≤0.012 | ≤0.005 | 3.25~3.70 | ≤0.12 | ≤0.05 | ≥0.020 |
Delivery status of 08Ni3DR steel plate:
Delivery status: Quenched and tempered, in order to improve the toughness of the steel, intermediate heat treatment (secondary quenching) can be carried out, and the steel plate with a thickness of not more than 12mm can also be delivered in two normalized + tempered states.
