What Is the Carbon Content of 410 Stainless Steel? 410 stainless steels have around 0.1% carbon content. It has a higher carbon content than some mild steels, contributing to higher strength and reduced ductility. The general range of 0.08–0.15% is much less than that of medium-carbon steels which have 0.30-0.60% carbon.

The characterization of corrosion behavior of AISI 420 steel, in 0.5M NaCl aqueous solution, was made in an electrochemical cell with 3 electrodes, connected at PG STAT 302N Autolab Potentiostat, at laboratory temperature. The medium used was a NaCl 0.5M solution with a pH of 6.26 and an electro-conductivity by 49.9 mS/cm. 1.
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
