Alloy 420 o se u'amea fa'ama'a'a, martensitic o se suiga o le Alloy 410. E tutusa ma le 410, o lo'o i ai le la'ititi o le 12% chromium, na'o le lava e tu'uina atu ai mea e fa'asa'o. Alloy 420 e maualuga atu le carbon content nai lo Alloy 410 lea ua mamanuina e sili ona lelei le malosi ma uiga ma'a'a. O lo'o i ai le fa'alelei lelei o le tulaga fa'amauina ae e mafai ona fa'ama'a'a e o'o atu i le Rockwell hardness 50 HRC, o le maualuga maualuga o le 12% chromium grades. Ona o ona mea faʻamaʻa, Alloy 420 e le masani ona faʻapipiʻiina, e ui lava e mafai. Martensitic u'amea uamea ua fuafuaina mo le maaa maualuga ma o nisi taimi o isi meatotino e i sina tikeri fetuunai. E maualalo le tete'e o le a'a nai lo togi masani austenitic ma e fa'atapula'aina le tele o le fa'aogaina i le leiloa o le ductility i lalo-zero vevela ma leiloa le malosi e ala i le soona ita i le vevela maualuga. O lona malosi sili ona leaga e maua pe a fa'ama'a'a le u'amea ma fa'aeleele i luga pe fa'aiila.
