SS420 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.

Speedy Metals Information for 420 Stainless SteelSpeedy Metals items. 420 stainless steel is a martensitic higher carbon version of types 410 and 416 stainless that can be hardened by heat treatment. It contains a minimum of 12 percent chromium, sufficient to give 420 corrosion resistance properties. It has good ductility in the annealed condition but is capable of being hardened up to 50 RHC. Stainless Steel - Grade 410 (UNS S41000)

  • IntroductionKey PropertiesCompositionMechanical PropertiesPhysical PropertiesGrade Specification ComparisonPossible Alternative GradesCorrosion ResistanceHeat ResistanceHeat TreatmentGrade 410 stainless steels are general-purpose martensitic stainless steels containing 11.5% chromium, which provide good corrosion resistance properties. However, the corrosion resistance of grade 410 steels can be further enhanced by a series of processes such as hardening, tempering and polishing. Quenching and tempering can harden grade 410 steels. They are generally used for applications involving mild corrosion, heat resistance and high strength. Martensitic stainless steels are AISI 4140 Chrome-Molybdenum High Tensile Steel
    • IntroductionChemical CompositionMachiningWeldabilityHeat TreatmentForgingStress RelievingAnnealingNormalizingNitridingAISI 4140 is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. AISI 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness. The desirable properties of the AISI 4140 include superior toughness, good ductility and good wear resistance in the quenched and tempered condition.
