For safe operations under cryogenic conditions, LNG storage tanks are generally made of 9% Ni steel plates. Recently, however, 7% Ni TMCP steel plate has been developed, which reduces the content of expensive Ni by nearly 20%. 7% Ni TMCP steel was standardized as SL7N590 in JIS G3127, "Nickel steel plates for pressure vessels for low temperature services," in March 2013, when application of
#TITLE# |KOBELCO - KOBE STEEL, LTD.In 1960, a destructive test involving a large-sized pressure vessel made of 9% Ni steel was carried out in the USA that proved that 9% Ni steel could be used safely without postweld heat treatment for stress relief. Since then, large capacity tanks made of 9% Ni steel have been constructed widely. (4G) along the bottom plate of an LNG tank

Development of 7%Ni-TMCP Steel Plate for LNG Storage These events led to the increase of constructions of Liquefied Natural Gas (LNG) storage tanks worldwide. The inner tank material for above ground LNG storage tanks have mostly been made of a 9% nickel steel plate over the last 50 years as it has excellent mechanical properties under the cryogenic temperature of 160deg-C.
Especially, this is the first time POSCOs 9% nickel steel was applied to fuel tanks. The worlds first LNG-powered bulk carrier, HL Green, in test operation. The oval tank surrounded by a yellow structure is the first LNG fuel tank to adopt POSCO 9% nickel steel. l With Fuel Tanks for LNG-powered Vessels, POSCO Is Ready to Set Sail!

The 5% Ni and 9% Ni alloys are conventionally welded using a nickel based filler metal. 6.5% Ni MMA electrodes are available but these are not capable of consistently providing adequate toughness much below -110°C. Consumables for welding the 9% Ni alloy have been developed; these typically contain 12% to 14% nickel.Masteel Supply 9% Nickel Alloy Steel PlatesMar 14, 2018 · Due to the resistance to low-temperature brittle fracture, 9% nickel steel plate can also be used in various other pressure vessels. 9% Nickel from Masteel Masteel has a global reputation for the supply of high quality cryogenic and pressure vessel steel and now adds 9% nickel
