I was looking up a Chemical Compatibility Database at Cole Parmer and it lists "Severe Effect (i.e. not recommended for any use )" for the Styrene & Hastealloy C pair.

Does styrene really attack Hastealloy? I find it hard to believe.
Or is it worried about styrene polymerization or something like that.

As you suggested it is probably polymerisation that is the problem here.

Thanks @disco.

Not that I'm planning on using any, SS works just fine.

I was just surprised 'coz the usual incompatibility culprits for metals are strong acids, bases, oxidizers etc. Not an organic usually.

Benzylic compounds, of which styrene could be loosely defined as one, are sensitive towards rust. Adding rust to a DSC experiment with one of these reduces the onset significantly. I suppose that here they are worried about leeching of metals which would cause rapid polymerisation.
The chemistry I did with such compounds was always in enamelled reactors.
