Aloyi chubu ndi mtundu wa chubu zitsulo zopanda msokonezo, zogawika mu chubu chosasunthika chokhazikika komanso kuthamanga kwamphamvu kosagwirizana ndi aloyi chubu. Zosiyana kwambiri ndi miyezo yopanga ndi mafakitale a machubu a aloyi, machubu a alloy alloy alloy amasintha mawonekedwe amawotchi. Kukwaniritsa zofunika processing zinthu. Kuchita kwake ndikwapamwamba kuposa chitoliro chachitsulo chosasunthika, mawonekedwe ake amapangidwa ndi Cr ambiri, motero amakhala ndi kukana kutentha kwambiri, kukana kutentha pang'ono komanso kukana dzimbiri. Machubu wamba a carbon seamless alibe aloyi kapena aloyi pang'ono. Aloyi chubu chimagwiritsidwa ntchito mafuta, zakuthambo, mankhwala, mphamvu yamagetsi, boiler, asilikali ndi mafakitale ena, chifukwa makina katundu aloyi chubu ndi zosiyanasiyana, zosavuta kusintha.

Chitoliro chachitsulo cha aloyi chimagwiritsidwa ntchito kwambiri pamagetsi, malo opangira magetsi a nyukiliya, boiler yothamanga kwambiri, kutentha kwapamwamba kwambiri, reheater ndi kuthamanga kwina kwakukulu komanso mapaipi ndi zida zotentha kwambiri. Zimapangidwa ndi chitsulo chamtengo wapatali cha carbon, alloy structural chitsulo ndi zitsulo zosapanga dzimbiri zosagwira kutentha ndi kugudubuza kotentha (extrusion, extrusion) kapena kupukuta kozizira (chojambula).
