EN10028-4.5Ni5Ni9Ni12Ni14X7Ni9X8Ni9 nickel-based low temperature structural steel Application
EN10028-4 5Ni, 9Ni, 12Ni14, X7Ni9, and X8Ni9 nickel-based low-temperature structural steels are extensively utilized in applications requiring exceptional performance at cryogenic temperatures across various industries. In the liquefied natural gas (LNG) sector, these steels are ideal for fabricating storage tanks, cryogenic pipelines, and terminals due to their superior toughness and resistance to brittle fracture at low temperatures. In the chemical industry, particularly for ammonia and hydrogen processing, 9Ni and X8Ni9 steels excel in pressure vessels and reactors exposed to extreme cold and corrosive environments. The power generation sector employs these materials in cryogenic heat exchangers and gas processing units, leveraging their high strength and weldability. Additionally, 12Ni14 and X7Ni9 are trusted in aerospace and industrial gas storage systems, ensuring reliability under severe thermal and mechanical stresses. Their ability to maintain structural integrity in sub-zero conditions makes them a preferred choice for EPC contractors and cryogenic equipment manufacturers worldwide.
