High temperature bolts

[schlebb]

I have come across a German grade for high temperature bolts, "460TS". I believe it came out of an ABB steam turbine unit.<br>
Is their a Canadian/American equivalent for this material? Where can I find a standard that covers this?

You could try a company called 'Bossard'. They make all types of high grade metric fasteners or go to ANSI website and look up the comparison for a fee.
