SG Iron Round Bar Mai Inganci | Sandan ƙarfe na Ductile Cast
Gabatarwar Samfuri
SG Iron Round Bar, wanda kuma aka sani da Spheroidal Graphite Iron ko Ductile Cast Iron Bar, kayan injiniya ne mai inganci wanda ake amfani da shi sosai a aikace-aikacen injiniya da tsarin gini. Ba kamar ƙarfen simintin launin toka na gargajiya ba, SG Iron yana ɗauke da spheroidal graphite, wanda ke ba shi ƙarfi, tauri, da juriya yayin da yake kiyaye ingantaccen injin da juriyar lalacewa.
Sandunan ƙarfe na SG sun dace da sassan da ke buƙatar ƙarfin gajiya mai yawa da juriya ga tasiri, kamar sassan silinda na hydraulic, sassan motoci, bearings, gears, da injunan gabaɗaya. Ana samun su a cikin matakai daban-daban kamar GGG40 (EN-GJS-400-15), GGG50 (EN-GJS-500-7), da ASTM A536 65-45-12, suna tabbatar da aiki a cikin aikace-aikace daban-daban.
- ana ƙera sandunan ƙarfe masu ductile bisa ga ƙa'idodin duniya. Ana bayyana nau'ikan ƙarfe masu ductile da ake amfani da su ta hanyoyi daban-daban bisa ga ƙasashe da ƙa'idodi daban-daban.
