These plates are available both in spot and futures forms for custom rolling. Provided by Henan Sante Steel Co., Ltd.; for custom rolling, contact 13083668868; same number for WeChat. ※Ni-based ultra-low temperature steels: I. Concept: Low-temperature steels refer to alloy steels suitable for use at temperatures below 0°C. Steel that can be used at temperatures below -196°C is called cryogenic steel or ultra-low temperature steel. II. Properties of low-temperature steel: ① The toughness-to-fracture transition temperature is lower than the operating temperature ； ②Strength meeting the design requirements ； ③The tissue structure remains stable at the operating temperature ； ④Good weldability and formability ； ⑤Certain special applications also require extremely low magnetic permeability, cold shrinkage rate, and so on. III. Product Overview: The 08Ni3DR (3.5% nickel)/07Ni5DR (5% nickel)/06Ni9DR (9% nickel) steel plate series is used in equipment for the production, storage, and transportation of liquefied petroleum gas, ethylene, and liquid natural gas. This material exhibits good low-temperature toughness in environments ranging from -60°C to -170°C. 06ni9DR (9% nickel) is used in above-ground and floating LNG storage tanks, cryogenic vessels, and cryogenic transmission pipelines; the material exhibits good low-temperature impact resistance at -170°C. 07Ni5DR (5% nickel) is used in the manufacture of ethylene transport and storage tanks, and the material exhibits good low-temperature impact resistance at -110°C. 08Ni3DR (3.5% nickel) is used in the manufacture of compressors, containers for nuclear wastewater, and storage tanks for coal-to-oil reactors; its products exhibit good low-temperature impact resistance at -101°C. IV. Comparison of grades between domestic and international standards: Domestic standard grade European standard grade American standard grade 06ni9DR X7Ni9, X8Ni9 SA553 07Ni5DR X12Ni5 SA645 08Ni3DR 12Ni14 SA203 V.
