ASTM a536 65-45-12 is an American Standard ductile iron.
The yield strength shall not be less than 448mpa, the tensile strength shall not be less than 310mpa, and the elongation (L0 = 50mm tensile test bar) shall not be less than 12%. I guess it's equivalent to QT450-10 in China.
malleable iron. Obtained from annealed white cast iron, graphite is distributed in flocculent form, which is called ductile iron for short. It has uniform microstructure and properties, wear resistance, good plasticity and toughness. It is used to manufacture parts with complex shape and can bear strong dynamic load.
Iron carbon alloy with carbon content of more than 2%. The carbon content of industrial cast iron is generally 2% ~ 4%. Carbon in cast iron exists mostly in the form of graphite and sometimes in the form of cementite.
White cast iron. The content of carbon and silicon is low, carbon mainly exists in the form of cementite, and the fracture is silver white. During solidification, shrinkage is large, and shrinkage cavities and cracks are easy to occur. High hardness and brittleness, unable to bear impact load. It is mainly used as a blank of malleable cast iron and for making wear-resistant parts.
