Adkeynta roobabka birta ah, oo loo yaqaan PH Steel, waxaa loola jeedaa noocabir aan lahaynkaas oo ku daraya noocyo kala duwan iyo qiyaaso kala duwan oo ah walxaha xoojinta, iyo noocyada kala duwan iyo tirada karbides, nitrides, carbonitrides iyo xeryahooda intermetallic ayaa ku soo daadaya iyada oo loo marayo habka adag ee roobka. Adkeynta roobabka birta aan lahayni ma leh oo kaliya xoog sare, laakiin sidoo kale waxay leedahay adayg wanaagsan iyo iska caabin daxalka. Roobka adkeynaya birta aan fiicnayn waxaa lagu tuuri karaa annagaFoundry kabka maalgashigasida ku cad sawiradaada, shuruudaha iyo xaalada isticmaalka.
Marka loo eego nuxurka walxaha alloy-ga ugu muhiimsan ee roobka ee adkeynaya birta aan fiicnayn iyo walxaha adag ee lagu daray, adkaynta birta dabaysha waxaa loo qaybin karaa afar qaybood oo soo socda:
(1)Roobabka Martensitic Adkeynta Birta Aanay Lahayn. Waxay guud ahaan ka kooban tahay kaarboon in ka yar 0.1%. Ku xooji adoo ku daraya walxo qallafsan (naxaas, aluminium, titanium iyo aluminium, iwm.) si aad u buuxiso awood la'aanta. Waxa ku jira chromium guud ahaan wuu ka sarreeyaa 17%, iyo qadar ku habboon oo nikel ah ayaa lagu daraa si loo hagaajiyo caabbinta daxalka.
(2)Maaraynta Roobka Adkeynta Birta Aanay Lahayn, oo leh kaarboonka aan ka sarreyn 0.03% si loo hubiyo adkaanta, caabbinta daxalka, alxanka iyo shaqeynta matrixka martensite, iyo 12% chromium si loo hubiyo caabbinta daxalka. Intaa waxaa dheer, cobalt element alloy ayaa lagu daraa si loo sii wanaajiyo saameynta daaweynta kulaylka ee birta.
(3)Roobab-Semi-Austenitic ah Oo adkeynaya Birta Aanaylahayn, taas oo ah, roobka ku meel gaadhka ah ee adkaynaya birta aan fiicnayn, oo ka kooban wax aan ka yarayn 12% chromium. Waxay leedahay kaarboon yar, iyo aluminium oo ah cunsurkeeda ugu weyn ee adkeynta roobabka. Roobabka noocan oo kale ah adkaynta birta aan lahayn ayaa leh waxqabad guud oo ka wanaagsan marka loo eego roobabka martensitic ee adkaynaya birta aan-suuxdinta lahayn.
(4)Roobab Austenitic ah oo adkeynaya Birta Aan Lahaynwaa bir bir ah oo leh qaab dhismeed austenite ah oo deggan labada dawladood ee la demiyey iyo kuwa gabowga. Waxyaabaha ku jira nikkel iyo manganese-ka ayaa aad u sarreeya, iyo waxa ku jira chromium ayaa ka sarreeya 13% si loo hubiyo caabbinta daxalka iyo caabbinta oksaydhka. Isla mar ahaantaana, roobka austenitic-ka ee adkeynaya birta birta ah waxay badanaa ku daraa titanium, aluminium, vanadium ama fosfooraska sida walxaha adkeynaya roobabka, waxayna ku daraan qadar yar oo boron, vanadium, nitrogen iyo walxo kale si loo helo sifooyin dhammaystiran oo heer sare ah.
Adkeynta roobabka birta aan fiicnayn ayaa si weyn looga isticmaalaa warshadaha horumarsan. Tusaale ahaan, roobabka caadiga ah ee adkeynaya birta aan fiicnayn ee 17-4PH waxaa loo isticmaali karaa in lagu sameeyo dhismayaal ka hooseeya 370 ° C kuwaas oo u baahan iska caabin daxalka, xirashada caabbinta, iyo xoog sare.
