Alloy elements ni gaw grey cast iron hta lang ai .

Gray cast iron hta jat bang da ai alloy elements ni hpe , graphitization elements, carburizing elements, bead stabilizing elements hte refined elements ni ngu ai daw mali hku garan mai ai.
N-gun ja ai lam hta, carbon, silicon, aluminum, sulfur, copper hte nickel elements ni gaw graphitized elements hku nna sawn la mai ai graphite hpe n-gun jaw ai hta lit nga ai. Raitim, elements ni a akyu gaw grai shai ai, ga shadawn, magri gaw silicon 20% daram rai nga ai. Nickel hte magri mang ni hta mung lahkawng lang lit nga ai: cocrystal galai shai ai aten hta graphitization hpe n-gun jaw ai; cocrystal galai shai ai aten hta graphitization hpe pat shingdang ya ai, dai gaw grau kaja ai n-gang ni hpe hpaw ya lu ai majaw, ngang grin ai element langai hku nna mung sawn la mai ai.
Titanium a akyu ni mung grai sawng nga ai. Madung hku tsun ga nga yang, titanium gaw n-gun ja ai carbide byin ai lam rai nga ai, raitim, shi a rawng ai lam gaw grai kaji ai aten (eg.<0.08%), its fine compounds can be used as the core of graphite, has the role of promoting graphitization.
Tin, antimony, manganese, molybdenum, chromium, vandium hte niobium ni yawng gaw graphite a marang hte rawt jat galu kaba wa ai lam hpe pat shingdang lu ai, carburn ni hpe hpaw ai a myit jasat hpe jat ya lu ai, yawng gaw carburns ni hta lawm ai. Molybdenum a akyu gaw shi a jat bang ai gumhpraw hte seng ai. Molybden gaw cast iron hta lawm ai,<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.
