KS D4301 - 1985  Standard for Gray Cast Iron

This is a Korea standard for stipulating the physical properties of gray cast iron, or called as grey iron. This standard is similar with the other standards for gray iron such as ASTM A48 in USA, DIN 1691 in Germany and ISO 185. The following is the main content of KS D4301-1985 standard for your reference.
