Corrosion Resistant Fasteners
Corrosion Resistant Fasteners
(OP)
Not sure if such a steel exists but here goes. We have a trench drain in a concrete slab. Draining into the trench is 50% Sodium Hydroxide(Caustic) and 93% Sulphuric Acid. Rather than form a ledge into the concrete to carry the trench grating, we're considering installing angle iron with bolts into the existing trench wall.
Good idea or Bad?

Interesting. *IF* the pH ends up anywhere near neutral you may be OK-assuming they are mixed well before they reach the steel. The steel will survive the caustic OK, but not the acid. If you need a metal to resist the acid, holler back.

Thanks to both of you.
My specialty is concrete so if I can ever be of help just ask.

I didn't get it all?
Is the NaOH and H2SO4 going down a tRench made of concrete or it is lined?

Does your concrete have a coating or sealant for protection?
[If not, I suggest a clear, penetrating epoxy sealer or a coating of Derakane vinylester epoxy]
Do you have an EPA or other government permit for this hazardous waste treatment process?
RE: Corrosion Resistant Fasteners
Kenvlach, this is not effluent and is NOT discharged directly into the environment. It gets recycled back into the process after it enters the trench.
