I am unaware of that specification, but would suggest strongly that you contact the crane manufacturer prior to any welding. They use some pretty high strength materials and unless you know what their repair procedure is, you may cause unintended consequences.

If I remember well, Charles has already given this suggestion on some other posting in this Forum and I agreed entirely with him.
DON'T weld anything on the crane boom or counterweight without having asked first for the manufacturer's instructions.
If you make a weld and something goes wrong (Murphy's law !!), the responsibility will be all yours. A crane boom weld that brokes can cause a disaster.

It is a 100ksi high strength Q&T steel. Look at p.13 in the following:

the crane manufacturer ask me to use an ox812 plate and for the moment i'm on the field(at sea). i have an 8mm plate that we use to repair a crane boom, i don't know exactly the grade but there is *DRILLIMAX 690* marked on that plate.
can you tell me the mining of this?
thanks.
