Nitrogen ion implantation on the mechanical properties of AISI 420

Nitrogen ions at various energy and dose have been implanted into the surface of AISI 420 martensitic stainless steel. • Nanohardness was improved by a factor of 2.3 when the implant energy and dose were 50 keV and 5 × 10 16 cm − 2.. 5 × 10 17 cm − 2 should be the suitable dose for the improvement of wear resistance.. Chromium nitrides …

AISI 420 martensitic stainless steel corrosion

A more noble corrosion behavior was observed for AISI 420 steel treated at 440 and 480 °C when compared to nitrided at 520 °C, due to the formation of a layer composed by α′ N, ε and γ′ phases. Corrosion resistance reduction is due to the chromium nitrides phases precipitation [14] AISI 420: 0.1 M NaCl: −260 to −230 mV a – Pitting

AISI 420 Stainless Steel (UNS S42000) | Forging Materials

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.
