I. 08Ni3DR is a steel plate used for low-temperature pressure vessels. The nominal carbon content is 0.08%, with the actual content not exceeding 0.10%. The nominal nickel content is 3%, while the actual content ranges from 3.25% to 3.70%. 08Ni3DR is widely used in the manufacture of reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, pressure vessels for nuclear reactors, liquefied petroleum gas cylinders, and turbine casings. II. Chemical composition of 08Ni3DR: 08Ni3DR can be ordered from Wuhan Yicheng Steel; delivery is fast. The values for CSiMnPSNiMoV are ≤0.10, 0.15–0.35, 0.3–0.8; ≤0.015, ≤0.005; 3.25–3.7, ≤0.12, ≤0.05 respectively. III. Mechanical properties of 08Ni3DR: Yield strength, tensile strength, elongation after fracture, bending diameter, impact temperature, and minimum impact energy – ≥300 Mpa, 480–610 Mpa, ≥21%, d=3a–10, 44°C, 48 J. IV. Delivery condition of 08Ni3DR: The 08Ni3DR steel plates are delivered in a quenched and tempered state. To improve the toughness of steel, intermediate heat treatment (secondary quenching) can also be carried out. Steel plates with a thickness of no more than 12 mm can also be delivered in a condition of two normalizations followed by tempering, with the tempering temperature being no less than 540°C. V. Application prospects of 08Ni3DR The mechanical properties of 08Ni3DR. With the development of modern industry, the world’s energy consumption is increasingly focused on gaseous fuels, especially natural gas. Natural gas is a clean, convenient, and efficient high-quality energy source. The world has abundant natural gas resources, with estimates suggesting reserves of 400–600 trillion cubic meters. At the current annual production level, it can be utilized for another two to three hundred years. However, natural gas is generally stored far from major consumption areas, which makes the storage of large quantities of natural gas and its long-distance transportation urgent issues that need to be addressed. If natural gas can be turned into a liquid state, its volume can be reduced by 600 times, which **lowers the costs of transporting and storing it**. The typical liquefaction temperature for natural gas is -162°C; therefore, LNG ships used for transporting liquid natural gas, as well as storage tanks for holding it, require the use of large amounts of low-temperature steel such as 06Ni9DR. As a green energy source, liquefied natural gas (LNG) is seeing increasing demand in China. There are over 20 LNG projects under construction along China’s coast and those that will be built in the next decade; these projects will make extensive use of 08Ni3DR steel plates for manufacturing LNG storage tanks. At present, most of these steel plates rely on imports.
