Sheradising

[Delta40]

My specifications require all bolts to be sheradised. This includes tempered anchor (holding-down) bolts that will be completely encased in concrete. I understand that the sheradising process requires heat in the range of 370-500 degress Celcius and am concerned about the heat affecting the tempered bolt strength. Is this a valid concern? Further, if the bolts are completely encased in concrete in an interior, controlled environment is the corrosion control provided by sheradising actually needed?

That's cooler than hot-dip galvanizing. Unless it's a specialized application, I doubt it will be a problem. If you're still in doubt, call a manufacturer or ask in one of the metallurgy forums.

How much cover will the encased bolts have? Will they be in a chloride rich environment?
