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

INTRODUCTION. 420 stainless steel is one of the basic martensitic stainless steels with a composition of Cr 12.0-14.0% and C 0.15% min with Fe balance. The carbon level is not limited in the specification but generally does not exceed 0.4%. Typically carbon is controlled in the range 0.20-0.30% depending on the desired hardness.
Anil untuk ASTM AISI 420 terbuat dari baja tahan karat. Temperatur anil subkritis (Direkomendasikan) untuk baja tahan karat AISI 420: dari 675-760 ° C (1245-1400 ° F); Udara dingin dari kisaran suhu, gunakan rentang suhu pemanasan atas untuk meminimalkan kekerasan. Kekerasan Rockwell yang sesuai adalah 94-97 HRB.
This type of AISI 420 stainless steel type contains 0.16% carbon, 13% chromium, and less nickel. It is more corrosion-resistant than AISI 420A because it contains more chromium. Applications that call for moderate hardness and corrosion resistance, such as knife blades and cooking utensils, frequently use AISI 420J1.
