Bir kulul

Heat-resistant steel refers to the steel with high temperature oxidation resistance and high temperature strength. High temperature oxidation resistance is an important condition to ensure the lasting work of the piece at high temperature. Steel parts in the high temperature air and other oxidation environment, oxygen and steel surface chemical reaction to form a variety of iron oxide layer, the oxide layer is very loose, lost the original characteristics of steel, easy to fall off . si loo wanaajiyo heerkulka ee heerkulka safka sare ee birta, walxaha loo yaqaan 'alfon', silikon, aluminium iyo lakabka oksium-ka, ama lakabka nasashada ee xasilloon, ama Al2o3, si looga ilaaliyo birta oksides dheeraad ah {{11 {11 {11} inta lagu daro, iyo aluminium-ka ee loo yaqaan 'ogmidinum' iyo aluminium-ka ayaa ka sii dari doona {{12} Sidaas oo kale, sidaa darteed birta sicir-bararka leh oo leh elemium-ka ugu weyn, silikon, aluminium-ga aluxiliary, oo gaagaaban, heerkulka sare ee heerkulka u caabbinta birta ayaa kaliya laxiriira kaliya isku-darka kiimikada {14}
Awoodda heerkulka sare waxaa loola jeedaa awoodda birta si ay ugu hor istaagto culayska farsamada muddo dheer heerkulka farsamada, taasina waa, taasina waxay ku sii kordhayaan kordhinta waqtiga, iyo cirifka caagga ah ee birta heerkulka sare ah waxaa sababa Tilmaamaha 'Crystal' iyo warhdinta xuduudaha ee {{2} ee loo adeegsado in lagu wanaajiyo awoodaha heerkulka ee ugu badan ee birta, TITADEM, TITANDEM, TITADIUM, ECT {{5}, wuu xoojin karaa Matrix ee birta, hagaajinta heerkulka dib-u-eegista, laakiin sidoo kale waxay sameyn kartaa wajiga kor u qaadida xargaha '' '', sida CR23C6, iwm {{8}, iwm {{8}, iwm {{8}, {}}, oo aan lagu darin}, badiyaa si loo helo Austite {{10} Austitite ayaa aad u dhow oo ku saabsan atom-ka Ferrite, iyo xoogga iskudhafka ah ee is-dhexgalka ah, sidaa darteed xoojinta heerkulka ugu badan ee birta u adkaysta ah, laakiin sidoo kale waxay la xiriirtaa unugyada {{14}
