一、球墨铸铁的性能球铁铸件差不多已在所有主要工业部门中得到应用,这些部门要求高的强度、塑性、韧性、耐磨性、耐严重的热和机械冲击、耐高温或低温、耐腐蚀以及尺寸稳定性等。为了满足使用条件的这些变化、球墨铸铁现有许多牌号,提供了机械性能和物理性能的一个很宽的范围。 Ductile iron performance Ductile iron castings have been applied in almost all major industrial sectors, which require high strength, ductility, toughness, abrasion resistance, severe thermal and mechanical shock, high temperature or low temperature, corrosion resistance As well as dimensional stability and so on. To meet these variations in service conditions, many grades of nodular cast iron offer a wide range of mechanical and physical properties.
