347: ƙara ƙarfin niobium mai karko, wanda ya dace da sassan kayan aikin jirgin sama da kayan aikin sinadarai.
Jerin 400: Ferritic da martensitic bakin karfe, manganese kyauta, na iya maye gurbin bakin karfe 304 zuwa wani matsayi
408: kyakkyawan juriya mai zafi, raunin lalata lalata, 11% Cr, 8% Ni.
409: samfurin mafi arha (Burtaniya da Ba'amurke), galibi ana amfani da shi azaman bututun ƙarewar mota, na ƙarfe ne na baƙin ƙarfe (ƙarfe chromium).
410: martensite (ƙarfe mai ƙarfi na chromium), juriya mai kyau, juriya ta lalata lalata.
416: kari na sulfur yana inganta aiwatar da kayan.
420: “kayan aikin yankan” martensitic karfe, kwatankwacin Brinell high chromium steel, farkon bakin karfe. Hakanan ana amfani dashi don wuƙaƙan tiyata. Yana da haske sosai.
430: bakin ƙarfe mai ƙarfi, mai ado, misali, kayan aikin mota. Kyakkyawan tsari, amma ƙarancin zafin jiki da ƙwarin lalata.
440: steelarfin kayan ƙarfe mai ƙarfi, tare da ɗan ƙaramin abun cikin carbon, na iya samun ƙarfin yawan amfanin ƙasa bayan ingantaccen maganin zafi, kuma taurin zai iya kaiwa 58hrc, wanda yana daga cikin baƙin ƙarfe marasa ƙarfi. Misali mafi yawa na aikace-aikace shine "reza ruwa". Akwai samfuran gama gari guda uku: 440A, 440b, 440C, da 440f (sauƙin aiwatarwa).
Jerin 500: ƙarfe mai ƙarƙan karfe mai haɗari na chromium.
Jerin 600: Martensite Hazowa Hardening Bakin karfe.
