We want to strengthen the leg connections of tubular towers with flanged joints by replacing the bolts, the rest of the connection can carry the additional load. The use of grades 12.9 or 14.9 is discouraged due to the relatively low ductility and the increased risk of hydrogen embrittlement.
Can anybody suggest a suitable materials for the bolts, typically M16 (5/8"
bolts with required working loads of 85kN (19kips) and 100kN (22kips) in a galvanised steel structure exposed to the weather.
Thanks
