SS904L AISI 904L uamea uamea (UNS N08904)
Folasaga o oloa
AISI 904L uamea u'amea (UNS N08904) o se u'amea maualuga austenitic uamea. Pe a faatusatusa i le 316L, o le SS904L e maualalo le kaponi (C), maualuga le chromium (Cr), ma pe tusa ma le faaluaina o le nickel (Ni) ma le molybdenum (Mo)316L, lea e maua ai le maualuga maualuga o le vevela o le faʻamaʻiina o le faʻamaʻiina, faʻafefeteina o le pitting, ma le teteʻe i le faʻaitiitia o le acid (faʻataʻitaʻiga, sulfuric acid). Nitrogen (N) e mafai ona faʻaitiitia ai le fua o le chromium carbide precipitation, ma faʻaitiitia ai le lagona o le faʻalogo, e faʻaleleia ai foi le teteʻe i pitting ma crevice corrosion e mafua mai i chlorides. Ae maise o lona fa'aopoopoina o le kopa (Cu) e fa'aoga ai mo fa'atonuga uma o le sulfuric acid.
Alloy 904L e sili atu le lelei nai lo isi austenitic u'amea u'amea ona o le maualuga fa'afefiloi o nickel ma molybdenum. O le togi e le fa'amaneta i tulaga uma ma e sili ona lelei le fa'atulagaina ma le fa'alelei. O le fausaga austenitic e maua ai foi e lenei vasega le malosi sili, e o'o lava i le vevela o le cryogenic O le maualuga o le chromium e fa'aolaina ma fa'atumauina se ata pa'u e puipuia ai mea i le tele o si'osi'omaga pala. E leai se tulaga lamatia o le intercrystalline corrosion i luga o le malulu poʻo le uʻamea ona o le maualalo o le carbon content. Ole maualuga ole vevela ole tautua ile 450°C. O lenei vasega e sili ona aoga ile fa'atonuga ma meafaigāluega tubing applications e le talafeagai le 316 ma le 317L.
Alloy 904L na muamua fausia e tetee atu i siosiomaga o loʻo i ai le sulfuric acid faʻafefe. E ofoina atu foi le tetee lelei i isi acids inorganic e pei o le vevela phosphoric acid faapea foi ma le tele o meaola.
Alloy 904L e faigofie ona faʻapipiʻiina ma faʻatautaia e faiga masani faʻatau faleoloa.
904L u'amea u'amea (SS904L) o lo'o fa'aaogaina i le suau'u, vaila'au, fetilaisa, olo tau atina'e o le gataifale, tane, paipa ma paipa ma fa'afesuia'i vevela. E fa'aogaina fo'i e Rolex ma isi tagata gaosi uati e fai ai uati
