Powder metallurgy (PM) AISI 430L (UNS S43000) sintered in a nitrogen-hydrogen atmosphere was investigated to obtain an acceptable balance of mechanical properties and corrosion resistance. High-temperature solution annealing (1,150°C, 60 min) and some post-sintered aging heat treatments (100, 200, 300, 375, 675, and 850°C) for different times (90 min, 4, 6, 8, and 48 h) were performed. The effects of nitrogen and temperature/time aging on localized corrosion were analyzed by using an exposure method (ferric chloride test, ASTM G48) and anodic polarization measurements (ASTM G5). Experimental results showed that high-temperature solution annealing provides even better corrosion resistance than the material sintered in vacuum. Also, aging at low temperatures shows a positive effect on mechanical reinforcement without losing significant levels of corrosion resistance. 6 Corrosion 65 ARTICULO García, C. 46195 Martín, F. 46196 De Tiedra, P. 46197 175702 175702 0 0 0 0 243521 BAAB BAAB 2026-03-05 200047603 0 200047603 2026-03-05 18:56:05 2026-03-05 ARTICULO
