O le 253Ma alloy e iai uiga nei:
253MA o se u'amea austenitic fa'afefe vevela ua fuafuaina mo talosaga e mana'omia ai le malosi o le fetolofi maualuga ma le lelei o le pala.O lona fa'aogaina o le vevela o le 850-1100 °C.
O le vailaʻau vailaʻau o le 253MA e paleni, lea e maua ai e le uamea le sili ona talafeagai o mea faʻapitoa i le vevela o le 850 °C-1100 °C, maualuga le maualuga o le faʻamaʻiina, ma le fua o le vevela e oʻo atu i le 1150 °C;e matua'i maualuga le tete'e o le fetolo Gafatia ma le malosi o le malepelepe;lelei tete'e i le vevela vevela ma tetee i le pulumu pala i le tele o ala o faasalalauga gaseous;maualuga le maua o le malosi ma le malosi faʻamalosi i le maualuga o le vevela;lelei formability ma weldability Ma lava machinability.
I le faaopoopo atu i elemene faʻafefiloi chromium ma nickel, 253MA uʻamea uʻamea o loʻo i ai foʻi se vaega itiiti o le uʻamea eleele (Rare Earth Metals, REM), lea e faʻaleleia atili ai lona malosi antioxidant.Ua fa'aopoopoina le nitrogen e fa'aleleia atili ai mea fetolofi ma fai ai lenei sila ma austenite atoatoa.E ui lava o le chromium ma le nickel i totonu e fai si maualalo, o lenei u'amea u'amea e tele uiga tutusa maualuga vevela e pei o le u'amea u'amea maualuga uamea ma nickel-faavae.
253Ma talosaga:
253MA o loʻo faʻaaogaina lautele i masini faʻapipiʻi, mea faʻapipiʻi afi, faʻafefeteina uʻamea, ogaumu ma faʻaauau mea faʻapipiʻi, masini taʻavale (ogāumu faʻavevela), ogaumu vevela vevela ma mea faʻaoga, masini minerale ma masini sima.
