Low-temperature nickel steel is a type of alloy steel specifically designed to maintain toughness and ductility in extremely cold environments. By adding nickel—typically between 3.5% to 9%—the steel’s ductile-to-brittle transition temperature is significantly lowered. This prevents catastrophic brittle fracture, which is a major risk for carbon steels at low temperatures.
These steels exhibit excellent impact strength and are relatively easy to fabricate and weld. Due to these properties, they are the preferred material for critical applications exposed to cryogenic temperatures, such as storage tanks for liquefied gases (like LNG), components in the cryogenic industry, and structures in arctic environments. Their reliability ensures safety and integrity where thermal stress is a primary concern.
Low-temperature Nickel steel is used for storage, treatment and transportation of liquid ethylene
and methane, liquefied natural gas, liquid oxygen, liquid nitrogen and other liquid gas storage tank devices and pipelines, among which 06Ni9DR steel plate has passed the ABS classification society certification.
