Galvanized High Strength Bolting
Galvanized High Strength Bolting
(OP)
Hi,
Someone told me, "High strength bolting (>150,000 psi [1100 MPa] ultimate tensile strength) shall not be hot-dip galvanized, but shall be coated by mechanical galvanizing or with an inorganic zinc rich primer"
However, I have no idea about this reason.
and more,
I thought that B7 bolting and galvanized B7 bolting have different mechanical properties.
Is it wrong???
