WebOct 23, 2001 · Grade 420 stainless steels are welded using welding rods, coated with grade 420 metals, to achieve high-strength joints. During the process, steels are pre-heated at 150 to 320°C and post-heated to 610 to 760°C. In the “as welded” condition, parts are welded using grade 309 filler rods to achieve ductile joints. WebSep 10, 2024 · 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
