Ka soo horjeedka asalka horumarka warshadaha ee deg-degga ah, kuleylka - bir weyn ayaa noqday shey muhiim ah oo ku yaal beeraha tamarta, warshadaha kiimikada, iwm, sababtuna tahay heerkulka heerkulka heerkulka ah. Iyada oo horusocodka tikniyoolajiyadda, baaxadda dalabka kuleylka {{4 {4 {4 {4 {4 {4 {4 {4 {4 {4 {4 {4 {4 {4 {4 {4 {4 {4 {4 {4} {{4 {4 {4- birta iska caabbinta ayaa sii ballaaranaysa, iyo astaamaha waxqabadka ayaa sidoo kale soo jiidatay feejignaan badan.
The core advantage of heat-resistant steel lies in its excellent high-temperature strength and oxidation resistance. Deegaanka hoose ee hoostiisa, birta caadiga ah waxay u nugul tahay jilcida ama nadiifinta, taasoo dhalisay fashil qaab dhismeedka. Kuleyl {{5} birta u adkaysata ayaa sameeya filim oxide ah oo cufnaanta ah iyadoo la adeegsanayo walxaha loo yaqaan 'oxide' oo ku daraya walxaha loo yaqaan 'chroy walxaha sida chromium, nikkel, iyo molybdenum, oo si wax ku ool ah u sahlaysa heerkulka iyo huxan. Tusaale ahaan, kuleylka {{8 {8- bir koromsium ah oo ka badan 12% waxay ilaalin karaan deganaanshaha deegaan ka sarreeya 800 darajo waxaana si weyn loogu isticmaalaa kuleyliyeyaasha, kuleylka kuleylka iyo qalabka kale.
Intaa waxaa sii dheer, sareeya {0 0}}} qaab dhismeedka heerkulka kuleylka {{1} {{1} {1} {{1}- bir bir ah waa muuqaal kale. Creep waxaa loola jeedaa ifafaale in shey si tartiib tartiib ah u yaraanaya waqti dheer {{3-3} erey heer sare ah- xamuul heerkul ah. Iyaga oo la kaxeysanayo halabuurka daaweyn iyo hanaanka kuleylka, kuleylka casriga ah {{6 {6 {6 {6 {6} ah bir bir adag ayaa si weyn u yareyn kara heerka gurguurta ee heerkulka ka hooseeya heerkulka hoostiisa heerkulka iyo sareeya {{} {}} ah. Muuqaalkaani wuxuu ka dhigayaa in waxyaabaha la doorbido ee loogu talagalay qalabka ugu sarreeya sida qalabka dhamaadkooda sida marawaxadaha gaaska iyo matoorrada diyaaradaha.
Waxaa jira noocyo badan oo kuleyl ah -} bir bir ah, iyo moodooyin kala duwan ayaa ku habboon heerka heerkulka kala duwan. Tusaale ahaan, kuleylka ferritic - bir u adkaysta ah ayaa leh qiime jaban oo ku habboon jawiga dhexe iyo heerkulka hoose ee hoose; In kasta oo kuleylka aurantatic - bir u adkaysta ah ay leedahay nusl weyn oo ku jira oo ku noolaan kara awood heerkulka sareeya, waxaana badanaa loo isticmaalaa xaaladaha shaqada ee adag sida dib-u-celinta patrochemical. Iyada oo loo dallacsiinayo Ultra {{5}- tikniyoolajiyadda qarniga sare ee awooda, cilmi baarista iyo horumarka sareysa - kuleylka waxqabadka - bir kulul - bir bir ah oo iska cafiska ah ayaa noqday hotspot-ka.
Mustaqbalka, hormarinta tacliinta cusub ee tamarta iyo teknolojiyadda ilaalinta deegaanka, kuleylka - salka ugu adkaysta ayaa wajihi doona shuruudaha waxqabadka adag. Iyada oo loo marayo hal-abuurnimo iyo hagaajinta hanaanka, kuleylka - bir bir ah oo iska caabbiyayaasha ah ee ku saabsan astaanta tamarta dibada, iwm.
