Malleable Iron Casting Malleable iron castings have been widely accepted in American industry for more than 150 years. They possess ductility and strength on par with low carbon steels, making malleable castings suitable for a wide range of applications.
Typical Applications for Malleable Casting: Malleable casting is particularly well suited for Automotive Parts, Agricultural Equipment, Pipe Fittings, Electrical Fittings, Valve Components, Hardware Items, Tools, Pneumatic Fittings and Couplers, Railroad Hardware, Conveying, Ordinance Parts, Ornamental Items. Advantages of Malleable Casting: Malleable casting provides excellent surface finish. Good dimensional control, Good machinability, Better tool life. Allows freedom of design, Good detail. | Malleable Casting Specifications | Class | Tensile | Yield | Elong. | BHN | | ASTM A47 | 32510 | 50,000 | 32,500 | 10 | 156 max. | | SAE J158 | M3210 | 50,000 | 32,000 | 10 | 156 max. | | GM11M | | 50,000 | 32,625 | 10 | 156 max. | | ASTM A220 | 50005 | 70,000 | 50,000 | 5 | 179-228 | | SAE J158 | M4504 | 65,000 | 45,000 | 4 | 163-217 | | GM86M | | 69,600 | 47,850 | 5 | 163-207 | | ASTM A220 | 50004 | 80,000 | 60,000 | 4 | 197-241 | | SAE J158 | M5503 | 75,000 | 55,000 | 3 | 187-241 | | GM85M | | 79,750 | 59,450 | 3 | 197-241 | | ASTM A220 | 70003 | 85,000 | 70,000 | 3 | 217-269 | | SAE J158 | M7002 | 90,000 | 70,000 | 2 | 229-269 | | GM84M | | 100,000 | 79,750 | 2 | 241-269 | | ASTM A220 | 80002 | 95,000 | 80,000 | 2 | 241-285 | | SAE J158 | M8501 | 105,000 | 85,000 | 1 | 269-302 | | GM88M | | 104,400 | 84,825 | 2 | 269-302 | |
