Chinese Cast Material ZG230-450

ZG230-450 material is a Chinese cast carbon steel underGB/T 11352-2009 standard. Character Z means cast in Chinese "Zhu”, G character means steel in Chinese "Gang”. 230 indicates the min. Yield strength value of the casting. 450 means the the min. Tensile strength value of the casting. ZG230-450 carbon steel castings are mainly used for general engineering, various mechanical parts, such as base, gearbox shell.
