O u'amea lamolemole o u'amea maualuga ia e maualuga atu le fa'afefeteina pe a fa'atusatusa i isi u'amea ona o le tele o le chromium. Faʻavae i luga o latou fausaga tioata, ua vaevaeina atili i uʻamea ferritic, austenitic, ma martensitic.
Vasega 309 u'amea u'amea maualuga tete'e ma malosi fa'atusatusa i le 304 u'amea u'amea. O fa'amaumauga o lo'o i lalo o lo'o tu'uina mai ai se fa'amatalaga lautele o le sila u'amea 309 vasega.
Meatotino Lautele
Alloy 309 (UNS S30900) o se austenitic u'amea u'amea ua atiina ae mo le faaaogaina i le vevela maualuga talosaga tetee tetee. O le u'amea e tete'e i fa'ama'i e o'o atu i le 1900°F (1038°C) i lalo ole tulaga e le fa'ata'amilo. O le uila fa'aavela faifai pea e fa'aitiitia ai le fa'ama'iina i le 1850°F (1010°C).
Ona o le maualuga o le chromium ma le maualalo o le nickel content, Alloy 309 e mafai ona faʻaaogaina i le sulfur o loʻo i ai le ea e oʻo atu i le 1832 ° F (1000 ° C). E le fautuaina le u'amea mo le fa'aogaina i le maualuga o le atemosifia carburizing aua e fa'aalia ai na'o le fa'afefeteina o le carbon absorption. Alloy 309 e mafai ona faʻaaogaina i ni faʻamaʻi faʻamaʻi, nitriding, sima ma le uila uila, e ui lava, e tatau ona faʻaitiitia le maualuga o le vevela o le auaunaga.
A fa'avevela i le va o le 1202 - 1742°F (650 - 950°C) o le u'amea e fa'atatau i le sigma phase precipitation. O se vaifofo su'ega togafitiga i le 2012 - 2102 ° F (1100 - 1150 ° C) o le a toe fa'afoisia se tikeri o le faigata.
309S (UNS S30908) o le kaponi maualalo o le u'amea. E faʻaaogaina mo le faigofie o le fausiaina. 309H (UNS S30909) o se suiga maualuga kaponi ua atiaʻe mo le faʻaleleia atili o le fetolofi. O le tele o taimi o le tele o le saito ma le carbon content o le ipu e mafai ona ausia uma le 309S ma le 309H manaoga.
Alloy 309 e mafai ona faigofie ona faʻapipiʻiina ma faʻatautaia e faiga masani faʻatau oloa.
