Odatda kulrang quyma temirda ishlatiladigan qotishma elementlar

Kulrang quyma temirga qo'shilgan qotishma elementlarni taxminan to'rt toifaga bo'lish mumkin, ya'ni grafitizatsiya elementlari, karbürizatsiya elementlari, boncuk stabillashadigan elementlar va tozalangan elementlar.
Quyma temirning qattiqlashishi jarayonida uglerod, kremniy, alyuminiy, oltingugurt, mis va nikel elementlari grafitlangan elementlar sifatida qaralishi mumkin bo'lgan grafitning shakllanishiga yordam berishda rol o'ynaydi. Biroq, elementlarning samaradorligi juda farq qiladi, masalan, mis kremniyning taxminan 20 foizini tashkil qiladi. Nikel va mis ham ikki tomonlama rolga ega: kokristal o'tish davrida grafitlanishni rag'batlantirish; kokristal o'tish davrida grafitizatsiyani inhibe qiladi, bu ko'proq nozik boncuklar hosil bo'lishiga yordam beradi, shuning uchun uni barqaror element sifatida ham ko'rib chiqish mumkin.
Titanning ta'siri ham murakkab. Umuman olganda, titan kuchli karbid hosil qiluvchi elementdir, ammo uning tarkibi juda kichik bo'lsa (masalan, 2000 m.).<0.08%), its fine compounds can be used as the core of graphite, has the role of promoting graphitization.
Qalay, surma, marganets, molibden, xrom, vanadiy va niobiy grafitning yog'ishi va o'sishiga to'sqinlik qilishi mumkin, uglevodlarning hosil bo'lish tendentsiyasini kuchaytiradi va barchasi uglerodning barqaror elementlariga tegishli. Molibdenning ta'siri uning qo'shilgan miqdori bilan bog'liq. Cho'yandagi molibden miqdori,<0.8%, the effect of molybdenum is mild, which is to make the pearlite refinement, the content is the carburization stable element. It is generally believed that the role of manganese is to increase the amount of cast iron beads and improve the strength of cast iron. In fact, manganese is also multifaceted, when the content is high, it will make the graphite thick, thus reducing the strength of cast iron.
