Gabatarwar Samfuri
EN-GJS 400-15 / 500-7 Ductile Iron Sandunan ƙarfe ne masu inganci waɗanda aka ƙera bisa ga ƙa'idodin Turai, waɗanda aka ƙera musamman don aikace-aikacen da ke buƙatar ƙarfi mai yawa, kyakkyawan sassauci, da ingantaccen injin aiki. Ana samar da waɗannan sandunan da ƙaramin tsari na graphite na spheroidal, wanda ke ba da kyawawan halaye na taurin kai da juriya ga tasiri, wanda hakan ya sa suka zama zaɓi mai amfani don aikace-aikacen gine-gine da na inji.
Ana yaba wa jerin EN-GJS musamman a Turai saboda bayar da nau'ikan haɗin ƙarfi da tsawaitawa. EN-GJS 400-15 yana da kyakkyawan sassauci da tauri, yayin da EN-GJS 500-7 yana ba da ƙarfi mafi girma yayin da yake kiyaye isasshen sassauci. Waɗannan sandunan ƙarfe masu ductile sun dace da abubuwan da ke fuskantar matsin lamba mai maimaitawa, girgiza, ko matsakaicin tasiri. Ingancin injin su yana sa su dace da duka aikin roughing da kuma aikin kammalawa daidai.
- 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.
Ga waɗannan maki na ƙarfe mai ƙarfi (maki) da ake amfani da su a ƙarƙashin tsarin yau da kullun da yawa:
