What is the material of X7Ni9, X7Ni9 low temperature plate, X7Ni9 steel plate fixed rolling, X7Ni9 c

X7Ni9 belongs to low-temperature performance nickel alloy steel, which is widely used in chemical industry, such as chemical petroleum, chemical equipment de-ethanization tower, CO2 absorption tower, medium-pressure flash tower, cooler, de-ethethanization tower, reabsorption tower, compressor casing, propane cryogenic storage tank manufacturing and other chemical industries. Liquefied natural gas (LNG) storage tanks and transport vessels, the minimum use temperature can reach -196 °C

(X7Ni9) corresponding to the national standard 06Ni9DR Introduction: 06Ni9DR (9%Ni) steel plate is a special cryogenic pressure vessel plate for LNG storage tanks, and 06Ni9DR is a -196°C grade cryogenic pressure vessel steel plate. With its good low-temperature impact resistance and extremely low thermal deformation coefficient, it is widely used in LNG ships and LNG storage and transportation projects. The same series of grades include 08Ni***R (3.5 nickel), 08Ni5DR (5 nickel), and 06ni9dr (commonly known as 9 nickel steel)

X7Ni9 implementation standard European standard EN10028-4-2009 standard.

X7Ni9 delivery condition is generally Q+T (quenching + tempering).

With the increase of tempering temperature, the content of reversed austenite in the steel increases, the low-temperature impact toughness increases, and the matrix structure is purified, and the strength first increases and then decreases. When 580C tempering, with the decrease of holding time, the strength of the steel increases, the plasticity and toughness decrease, and the plasticity is lower than the standard value; QLT Thermal: The tempering process of the treatment is 580°C×60min.

X7Ni9 belongs to low-temperature steel, which is also a very common material in steel plates. X7Ni9 indicates that this material belongs to a steel plate with a nickel content of 9%, and nickel is also a frequent element added to steel plates.

X7Ni9 uses: mainly used in the production of pressure vessels, cryogenic equipment, cryogenic LNG storage tanks and other petrochemical equipment.
