Nickel Steels in Arctic Service (14004)
This paper presents an overview of nickel bearing steels used for arctic service in the oil and gas industry. The beneficial effects of nickel on fracture toughness at low temperatures, mechanical properties of thick section forgins and enhanced weldability of steels are discussed. Comment is also made regarding the limitation on the use of nickel steels with 1 percent nickel or higher in sour service, imposed by NACE Standard MR-01-75.
Materials to be examined include nickel steels for structural applicaitons (off-shore structures, storage facilities, etc.) and those specific to oil and gas production.
In addition, the emerging use of highly alloyed nickel-containing materials, such as duplex stainless steels for enhanced corrosion resistance, is addressed.
