Abstract

A steel foam component includes a steel body having a plurality of pores. The plurality of pores forms a generally uniform pattern throughout the body and occupies at least 20 percent of a volume of the body.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A steel foam component comprising:
 a steel body having a plurality of pores, the plurality of pores forming a generally uniform pattern throughout the body and occupying at least 20 percent of a volume of the body.   
     
     
         2 . The steel foam component of  claim 1 , wherein each of the plurality of pores has a similar geometric shape. 
     
     
         3 . The steel foam component of  claim 1 , wherein each of the plurality of pores is in fluid communication with at least one other pore of the plurality of pores. 
     
     
         4 . The steel foam component of  claim 1 , wherein the plurality of pores occupies between about 20 percent and about 60 percent of the volume of the body. 
     
     
         5 . The steel foam component of  claim 1 , wherein the plurality of pores occupies between about 40 percent and about 60 percent of the volume of the body. 
     
     
         6 . The steel foam component of  claim 1 , wherein the body includes a first face and a second face spaced apart from the first face, and wherein the first face and the second face are continuous steel. 
     
     
         7 . The steel foam component of  claim 6 , wherein the body also includes a peripheral edge extending between the first face and the second face, and wherein at least one of the plurality of pores communicates through the peripheral edge. 
     
     
         8 . The steel foam component of  claim 6 , wherein the first face and the second face are square in shape. 
     
     
         9 . The steel foam component of  claim 1 , wherein the plurality of pores is arranged in a series of rows and a series of columns within the body. 
     
     
         10 . The steel foam component of  claim 9 , wherein the series of rows is arranged parallel to a first axis and the series of columns is arranged parallel to a vertical axis, the second axis being perpendicular to the first axis. 
     
     
         11 . The steel foam component of  claim 9 , wherein the plurality of pores is further arranged in pore layers along a third axis, the third axis being perpendicular to the first axis and the second axis. 
     
     
         12 . The steel foam component of  claim 1 , wherein each of the plurality of pores is spherical in shape. 
     
     
         13 . The steel foam component of  claim 1 , wherein each of the plurality of pores is an empty void. 
     
     
         14 . The steel foam component of  claim 1 , wherein the steel body is in the shape of a rectangular prism.
