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.
When no heat treatment is required,the manufacturer or processor at his option may heat treat the plates by normalizing and then stress relieving to meet the material specification.If approved by the purchaser,cooling rates faster than those obtained by cooling in air are permissible for improvement of the toughness,provided the plates are subsequently tempered in the temperature range from 595 toAlloy 17-4 PH Precipitation Hardening - Sandmeyer SteelGeneral PropertiesCorrosion ResistanceMechanical PropertiesAlloy 17-4PH (UNS S17400),Type 630,is a chromium-nickel-steel precipitation-hardening martensitic stainless steel with an addition of niobium.17-4PH combines high strength and hardness with good corrosion resistance.The alloy is furnished in the solution annealed condition (Condition A).It should not be used at temperatures above 572°F (300°C) or for cryogenic service.Optimal mechanical properties can be obtained by subjecting the alloy to age hardening heat treatments.Heat treatment in the 900°F (See more on sandmeyersteelASTM A844/A844M-09 - Standard Specification for Steel 1.1 This specification covers 9 % nickel-alloy steel plates produced by the direct-quenching process.The plates are intended primarily for use in welded pressure vessels.1.2 The direct-quenching process consists of quenching the plates directly after rolling,without permitting the plates to cool below the critical temperature prior to Alloy 600 Heat Resistant Nickel Alloy Plate - Sandmeyer SteelSandmeyer Steel Company stocks Alloy 600 nickel alloy plate in thicknesses from 3/16 (4.8mm) through 2 (50.8mm) for applications in chemical and food processing equipment,paper mills,heat exchangers,and heat treating mufflers and retorts.
