9% Nickel Steel For use at cryogenic temperatures

Heat Treatment ArcelorMittal USA 9% Nickel steel is heat treated either by double normalizing and tempering (NNT) or quenching and tempering (QT).The tempering is conducted within a restricted range,that results in the formation of a small amount (5-15%) of metallurgically stable retained austenite,which is very important in developing the9% Nickel Steel for LNG and Cryogenic Applications·By reducing the carbon content of steel and increasing the proportion of Nickel,the crystal structure of the alloy is altered so that it can behave in a ductile manner at very low temperatures.After heat treatment,9% Nickel steel can meet requirements for ductility at temperatures as low as -196°C.1 Incidentally,LNG can be stored at temperatures below -162°C.9.ASTM A553 / A553M - 17e1 Standard Specification for The plates shall be tempered and hardened by heat treatment.The specimens shall be subjected to tension and Charpy V-notch impact tests. 1.1 This specification 2 covers 7,8,and 9 % nickel alloy steel plates for use in the water quenched and tempered condition intended for the fabrication of welded pressure vessels.
