B22C 9/00
B22C 7/02

US Classification:

420 8, 164131, 164 34, 164349

Abstract:

A method of casting a low alloy steel using a mold is disclosed. The method includes receiving the mold having a foam pattern disposed within a sand casing. The received foam pattern is coated with a permeable refractory coating and is disposed between compacted sand and the sand casing. The method further includes pouring a molten metal comprising a low alloy steel having a carbon content in a range from about 0.1 to about 0.4 percent into the mold so as to vaporize the foam pattern and remove gasification products through the permeable refractory coating, to form a low alloy steel casting. Further, the method includes removing the low alloy steel casting from the mold.
