Admisce 904L (UNS N08904) est ferrum super austeniticum immaculatum, quod moderatum ad altitudinem corrosionis resistentiae destinatur in amplis ambitus processuum. Coniunctio magni chromii et nickel contenti, additamentis molybdaeni et cupri copulata, optimae corrosioni resistentiae bonum confirmat.
Cum chemistry - 25% nickel et 4.5% molybdaeno, 904L bonam vim praebet corrosio chloridi resistendi crepuit, pitting et corrosio generalis resistentiae superior 316L et 317L molybdaeno ferro incorrupta auctus est.
Admisce 904L principio elaboratum est ut ambitus cum acido sulphurico diluto sustinerent. Etiam bonam resistentiam praebet aliis acida inorganica, sicut acidi phosphorici calidi ac acida organici maxime.
Admisce 904L facillime iuncta et discursum a norma taberna fabricationis practices.
