8. 321 uamea uamea. Titanium-stabilized austenitic uʻamea uʻamea, faaopoopo titanium e faaleleia intergranular corrosion teteʻe, ma e lelei maualuga-vevela mea tau masini, e mafai ona suia e ultra-maualalo carbon austenitic uamea. Se'i vagana ai taimi fa'apitoa e pei o le maualuga o le vevela po'o le fa'afefe o le hydrogen, e masani lava e le fautuaina mo le fa'aoga.

9. 347 uamea uamea. Niobium-stabilized austenitic uʻamea uʻamea, faʻaopoopo le niobium e faʻaleleia ai le faʻaogaina o le corrosion intergranular, o le faʻamaʻiina o le corrosion i le acid, alkali, masima ma isi faʻasalalauga e tutusa ma le 321 uʻamea uʻamea, lelei le faʻaogaina o le faʻaogaina, e mafai ona faʻaaogaina e pei o mea e faʻafefeteina ma anti. -corrosion O le uamea vevela e masani ona faʻaaogaina i le mana vevela ma fanua petrochemical, e pei o le faia o koneteina, paipa, faʻafefe vevela, oʻa, faʻagogo ogaumu. i totonu o ogaumu falegaosimea, ma ogaumu faagaau vevela.

10. 904L uamea stainless. Super atoatoa austenitic uamea u'amea o se ituaiga super austenitic uamea uamea na fatuina e OUTOKUMPU i Finelani. , O loʻo i ai le lelei o le faʻamaʻiina i mea e le faʻamaʻiina e pei o le sulfuric acid, acetic acid, formic acid ma le phosphoric acid, ma e iai foʻi le teteʻe lelei i le faʻamaʻi ma le faʻalavelave faʻafefe. E talafeagai mo concentrations eseese o le sulfuric acid i lalo ifo o le 70 °C, ma e lelei le corrosion teteʻe i acetic acid ma fefiloi acid o formic acid ma acetic acid i soʻo se faʻatonuga ma le vevela i lalo o le mamafa masani. O le uluai tulaga ASMESB-625 faʻavasegaina o ni uʻamea faʻavae nickel, ma o le tulaga fou faʻavasegaina e pei o le uamea. E na o togi tutusa o 015Cr19Ni26Mo5Cu2 sila i Saina. O nai tagata gaosi meafaifa'aili a Europa latou te fa'aogaina le sila 904L e fai ma mea autu. Mo se faʻataʻitaʻiga, o le paipa fua o le mita faʻafefe tele a E + H e faia i le 904L uamea, ma le pusa o Rolex uati e faia foi i le 904L uamea.

11. 440C uamea stainless. Martensitic u'amea u'amea e sili ona ma'a'a i u'amea fa'ama'a'a ma u'amea u'amea, ma le maaa o le HRC57. E masani ona faʻaaogaina e fai ai nozzles, bearings, valve cores, valve seats, lima, valve stems, etc.

12. 17-4PH uamea u'amea. Martensitic precipitation faʻamaʻaina uʻamea uʻamea ma le maaa o le HRC44 e maualuga le malosi, maʻaʻa ma e le mafai ona faʻaaogaina i le vevela i luga atu o le 300°C. E lelei le fa'afefeteina i le ea ma fa'afefeteina le suka po'o le masima. O lona tete'e corrosion e tutusa ma le 304 stainless sila ma 430 stainless steel. E fa'aaogaina e gaosia ai fa'alava i fafo, lau o le turbine, 'au o le valve, nofoa va'a, lima, fa'a'au o le valve Fa'atali.
