In order to achieve the correct phase balance it is important that duplex stainless steels are annealed within a fairly narrow temperature window, typically 950-1120 °C.Ferritic grades show ferritic solidification and are annealed at lower temperature, typically 750-1000 °C, to avoid ferrite grain growth. 21 4n cr stainless steelElgin 21-4N Stainless Steel Valve Set +.100 .

- IntroductionKey PropertiesCompositionMechanical PropertiesPhysical PropertiesGrade Specification ComparisonPossible Alternative GradesCorrosion ResistanceHeat ResistanceHeat TreatmentGrade 420 stainless steel is a high-carbon steel with a minimum chromium content of 12%. Like any other stainless steel, grade 420 can also be hardened through heat treatment. It offers good ductility in its annealed state and excellent corrosion resistance properties when the metal is polished, surface grounded or hardened. This grade has the highest hardness - 50HRC - among all the stainless steel grades with 12% chromium. Stainless steel grades that are similar to grade 420 stainless steels inclSS420 Grade AISI 420 Stainless Steel Properties, Heat AISI 420 steel (SS420) is very brittle under just hardened conditions and usually must be tempered to achieve useful toughness. The tempering temperature for 420 grade stainless steel after austenitizing:205-370 °C (400-700 °F). The corresponding tensile strength and Rockwell hardness are 1550-1930 MPa (225-280 ksi) and 48-56 HRC.
