Halabuurka SM520saxan bir ahwuxuu inta badan ka kooban yahay kaarboon (C), Silicon (Si), manganese (Mn), fosfooraska (P), baaruud (S), chromium (Cr), nikkel (Ni), molybdenum (Mo) iyo walxo kale. Waxaa ka mid ah, kaarboonku waa curiyaha qalfoofka birta, kaas oo wanaajin kara xoogga iyo adkaanta birta, laakiin sidoo kale hoos u dhigta caagga iyo adkaanta birta. Silikoon iyo manganese waxay samayn karaan xalal adag oo leh kaarboon, kordhinta xoogga iyo adkaanta birta iyadoo la ilaalinayo caagnimada iyo adkaanta. Fosfooraska iyo baaruuddu waxay hagaajin karaan waxqabadka goynta birta waxayna hagaajin karaan caabbinta daxalka ee birta. Chromium iyo nikkel waxay hagaajiyaan iska caabinta daxalka ee birta, gaar ahaan meelaha badda. Molybdenum waxay sifeyn kartaa miraha birta waxayna hagaajin kartaa waxqabadka guud ee birta. Waa in la ogaadaa in sifooyinka halabuurka ay yihiin arrimo muhiim ah oo saameeya sifooyinka farsamada iyo iska caabinta daxalkaSM520 saxan bir ahs, markaa waxay u baahan yihiin in lagu hagaajiyo iyadoo loo eegayo isticmaalka kala duwan iyo xaaladaha deegaanka si loo daboolo baahiyaha xaaladaha kala duwan ee codsiga.

SM520 saxan bir ahwuxuu leeyahay xoog wax-soo-saar sare iyo xoog cufan wuxuuna buuxin karaa shuruudaha dhismayaasha waaweyn ee qaadidda.

Halabuurka kiimikada SM520:

C: ≤0.2 Si: ≤0.55 Mn: ≤1.65 P: ≤0.035 S: ≤0.035

Qalabka makaanikada ee SM520:

Saxanka birta ah ee SM520 waxa uu leeyahay adayg wanaagsan, waxa uu u adkeysan karaa culaysyada waaweyn ee saamaynta leh, mana u nugul in uu jabo.

SM520saxan bir ahinta badan loo isticmaalo Buundooyinka, wiishashka, mishiinada macdanta, maraakiibta, saldhigyada tamarta, baabuurta, haamaha kaydinta batroolka, weelasha iyo walxaha kale ee alxanka ah ee qaab dhismeedka leh ee xambaarsan culaysyo firfircoon.

saxan bir SM520 leeyahay waxqabadka processing wanaagsan oo loo isticmaali karaa goynta, foorarsiga, qodista iyo hawlaha kale ee processing.

Saxanka birta SM520 wuxuu leeyahay waxqabadka alxanka wanaagsan wuxuuna buuxin karaa shuruudaha hababka alxanka ee kala duwan

Saxan bir ah SM520 waxay leedahay iska caabin daxalka wanaagsan waxayna u adkeysan kartaa daxalka meelo kala duwan oo adag muddo dheer. Iska caabbinta daxalka waa awooda shay uu uga hortagayo daxalka deegaanka daxalka waana tilmaame muhiim u ah nolosha adeegga maaddada. Saxanka birta ah ee SM520 wuxuu muujinayaa iska caabbinta daxalka wanaagsan ee deegaanka daxalka ah sida deegaanka badda iyo jawiga warshadaha, waxayna si wax ku ool ah u kordhin kartaa nolosha adeeggeeda.
