Ductile Wesi Sand Casting Centrifugal Pump Housing sakaPengecoran Chinakaro Layanan OEM Custom lan CNC Machining.
Wesi tuang minangka paduan tuang wesi-karbon karo unsur liyane sing digawe kanthi leleh maneh wesi babi, kethokan, lan tambahan liyane. Kanggo diferensiasi saka baja lan baja tuang, wesi tuang ditetepake minangka paduan tuang kanthi kandungan karbon (min 2.03%) sing njamin solidifikasi fase pungkasan kanthi transformasi eutektik.
Gumantung ing spesifikasi kimia, wesi cor bisa non-alloyed utawa alloyed. Wesi campuran luwih akeh, lan ngemot komponen umum sing luwih dhuwur, kayata silikon lan mangan, utawa tambahan khusus, kayata nikel, kromium, aluminium, molybdenum, tungsten, tembaga, vanadium, titanium, plus liyane. Umumé, wesi tuang bisa dipérang dadi wesi abu-abu, wesi ulet (wesi nodular), wesi tuang putih, wesi grafit kompak lan wesi tuang sing gampang dibentuk.

wesi cast ductile, kang uga disebut wesi cast nodular, grafit spheriodal cast wesi utawa mung wesi SG kanggo short, makili klompok wesi cast. wesi cast nodular entuk grafit nodular liwat spheroidization lan perawatan inokulasi, kang èfèktif mbenakake mechanical saka wesi cast, utamané plasticity lan kateguhan, supaya diwenehi kekuatan luwih saka baja karbon.
Casting wesi ulet duwe kinerja panyerepan kejut luwih saka baja karbon, nalika casting baja karbon duwe weldability luwih. Lan kanggo sawetara ombone, ing casting iorn ductile bisa duwe sawetara pagelaran saka nyandhang resistanting lan teyeng. Dadi casting wesi ductile bisa digunakake kanggo sawetara omah pompa utawa sistem sumber banyu. Nanging, kita isih kudu nggawe pancegahan kanggo nglindhungi saka nyandhang lan karat.
Wesi ulet dudu bahan tunggal nanging minangka bagean saka klompok bahan sing bisa diprodhuksi kanthi macem-macem sifat liwat kontrol struktur mikro. Karakteristik umum saka klompok bahan iki yaiku wangun grafit. Ing wesi ulet, grafit ana ing wangun nodul tinimbang serpihan kaya ing wesi abu-abu. Wangun sing cetha saka flakes grafit nggawe titik konsentrasi stres ing matriks logam lan wangun bunder saka nodules kurang, saéngga nyandhet nggawe retak lan nyediakake ductility meningkat sing menehi jeneng paduan. Dadi umume, yen wesi ductile bisa nyukupi syarat sampeyan, wesi ductile bisa dadi pilihan pertama, tinimbang baja karbon kanggo casting sampeyan.
