Supply of 08Ni3DR cryogenic pressure vessel plate 08Ni3DR steel plate is a steel plate for ultra-low temperature vessels. It is specially developed to get rid of China's long-term dependence on imports and meet the increasing domestic demand. It is used to manufacture LNG storage tanks and ultra-low temperature vessel steel plates for LNG ships that store and transport liquefied natural gas. The invention discloses a large-thickness Ni-based steel plate for cryogenic vessels and a production method thereof, which is smelted from the following mass percentage components:: C 0.07%～0.10%, Si 0.15%～0.30%, Mn 0.68%～0.80%, P≤0.008%, S≤0.003%, Ni 3.60%～3.70%, Cr 0.18%～0.25%, Mo 0.09%～0.12%, Nb 0.010%～0.020%, Ti 0.010%～0.020%, Alt 0.020%～0.050%, the balance is Fe and trace amounts of inevitable impurities ； The thickness of the steel plate is 100mm～150mm. This steel plate uses Ni-Cr-Mo-Nb-Ti ferrite steel to produce a 100mm~150mm thick 08Ni3DR (3.5Ni) steel plate that meets the requirements of low-temperature pressure vessels. It is used in the production of low-temperature equipment such as methanol scrubbers, methanol mist catchers, H2S concentration towers, etc. It has good welding performance and low-temperature impact performance. This steel plate has good low-temperature impact toughness, especially the -101℃ impact energy of the weak part of the steel plate at 1/2 of the plate thickness is >80J ； Low C content and therefore good weldability ； The thickness of the steel plate can reach 150mm, and the structure is uniform and fine, with minimal non-metallic inclusions. 08Ni3DR steel plate delivery status delivery status: Quenching and tempering, in order to improve the toughness of steel, intermediate heat treatment (secondary quenching) can be performed. Steel plates with a thickness of no more than 12mm can also be delivered in two normalizing + tempering states. Wugang Company successfully trial-produced the ultra-low temperature 08Ni3DR steel plate with a thickness of 150mm in China. The product’s flaw detection meets the national standard level one and has excellent performance. At this point, all localization of ultra-low temperature 08Ni3DR steel plate production has become a reality in Wugang, which can provide all specifications of ultra-low temperature steel plates used in the manufacturing of a complete set of cryogenic equipment for the chemical industry. 08Ni3DR steel plates are mainly used in the manufacturing of ultra-low temperature equipment such as large cryogenic storage tanks and pressure vessels in the chemical industry. The maximum thickness of the steel plates required currently is 130mm. Previously, the 08Ni3DR steel plate developed by Wugang with an impact temperature of -100°C has passed the * * In the review organized by the Boiler Vessel Standards Committee, the maximum thickness of the review was 100mm, which is at the leading level in the country. However, 08Ni3DR steel plates with a thickness of 100mm to 130mm are necessary for manufacturing low-temperature equipment. No domestic steel mill can supply them, and they can only be imported from abroad. In addition, in order to ensure the consistency of the performance of the entire set of low-temperature equipment, equipment users usually also import 08Ni3DR steel plates below 100mm, which makes domestic 08Ni3DR steel face severe challenges. In order to meet the domestic market demand and increase the product's share in the high-end market, Wugang has developed ultra-thick 08Ni3DR steel plates. The 150mm thick 08Ni3DR steel plate successfully trial-produced this time has fully qualified after comprehensive performance inspection by a professional authoritative organization.
