W 24X117 vs IPE V 600
W 24X117 is an W section from the American AISC Shapes Database; IPE V 600 is the closest equivalent in the European (Continental) range. They are close to interchangeable in bending: 5358.6 cm³ against 5320 cm³ of plastic modulus, a difference of 0.7%. W 24X117 is the lighter of the two at 174.1 kg/m against 184 kg/m, a saving of 5.4% on steel weight. Both are about 618 mm deep, so either fits the same construction zone.

How to choose between them
On stiffness, W 24X117 has the larger second moment of area: 147,346 cm⁴ against 142,000 cm⁴, a difference of 3.8%. This matters more often than the strength comparison, because on normal floor spans deflection rather than bending capacity sets the beam size - so if the two are close on modulus but apart on inertia, the stiffer one is usually the better answer even when it is not the stronger one.
Measured as bending capacity per kilogram of steel, W 24X117 is the more efficient section: 30.8 against 28.9 cm³ per kg/m, 6.5% better. Over a floor of repeated beams that difference is real tonnage, though it is often outweighed by whichever section the fabricator can actually source.
The two diverge much more about the minor axis: W 24X117 has 1170 cm³ of minor-axis plastic modulus against 780 cm³, 50.0% more. If the member sees any minor-axis bending, or if it is unrestrained over a long length and lateral-torsional buckling governs, that gap decides the comparison even though the major-axis numbers looked equivalent.
These come from different catalogues, so treat the swap as a design change rather than a like-for-like substitution. W sections are specified to AISC Shapes Database v16.0 and IPE to EN 10365 · Continental Steel; the steel grades, tolerances and available lengths differ, connection details and bolt gauges are set out differently, and the two are rarely both stocked in the same market. Check availability before changing a section on a drawing to save 5.4% weight.
In short, W 24X117 is the stronger section and W 24X117 is the lighter one; where those are the same section, it is the clear choice, and where they are not, decide on whether your design is governed by capacity or by tonnage.
