Chitoliro chachitsulo cha aloyi chimagwiritsidwa ntchito makamaka mu malo opangira magetsi, mphamvu ya nyukiliya, boiler yothamanga kwambiri, superheater yotentha kwambiri komanso chotenthetsera madzi ndi mapaipi ena okwera kwambiri komanso otentha kwambiri, chimapangidwa ndi chitsulo cha kaboni chapamwamba kwambiri, chitsulo chopangidwa ndi aloyi ndi chitsulo chosapanga dzimbiri chosagwira kutentha, pogwiritsa ntchito kutentha kotentha (extrusion, expansion) kapena kuzizira (kukoka).

Ubwino waukulu wa chitoliro cha Alloy Steel ndikuti chimatha kubwezeretsedwanso 100%, zomwe zikugwirizana ndi njira yadziko lonse yotetezera chilengedwe, kusunga mphamvu komanso kusunga chuma. Ndondomeko yadziko lonse imalimbikitsa kukulitsa gawo logwiritsira ntchito chitoliro cha Alloy champhamvu kwambiri. Pakadali pano, kugwiritsa ntchito chubu cha alloy ku China kumawerengera theka lokha la kugwiritsa ntchito chitsulo chonse m'maiko otukuka. Kukula kwa gawo logwiritsa ntchito chubu cha alloy kumapereka malo okulirapo pakukula kwa makampani. Malinga ndi kafukufuku wa gulu la akatswiri a alloy Pipe Branch of China Special Steel Association, kufunikira kwa chitoliro cha alloy champhamvu kwambiri ku China kudzawonjezeka ndi 10-12% pachaka mtsogolo. Chitoliro cha alloy ndi chitoliro chachitsulo malinga ndi kupanga zinthu (ndiko kuti, zinthu) kuti zifotokozedwe, monga momwe dzinalo likusonyezera ndi chitoliro cha alloy; Ndipo chitoliro chopanda msoko ndi chitoliro chachitsulo malinga ndi njira yopangira (msoko wopanda msoko) kuti zifotokozedwe, chosiyana ndi chitoliro chopanda msoko ndi chitoliro cha msoko, kuphatikiza chitoliro chowongoka cha welding ndi chitoliro chozungulira.

Zipangizo za chubu cha alloy zili motere:

16-50Mn, 27SiMn, 40Cr, 12-42CrMo, 16Mn, 12Cr1MoV, T91, 27SiMn, 30CrMo, 15CrMo, 20G, Cr9Mo, 10CrMo910, 15Mo3, 15CrMoV, 35CrMoV, 45CrMo, 15CrMoG, 12CrMoV, 45Cr, 50Cr, 45CrNiMo, ndi zina zotero.
