 103, 167, and 187 are SJI standard joist designations. The 50 year Steel Joist Compilation has listing for the load capacities. A 103 joist is 10" deep, a 167 joist is 16" deep and a 187 joist is 18" deep.

What depth is the X179 joist? If it is a standard depth, you might be able to estimate the load capacity.
