Metal used to construct Ramshorn Hooks

[andybarter043]

I am looking for information on the material, grade and method of manufacture of two ramshorn hooks (each rated at 925 tonnes with a lifting capacity of 37000 tonnes) on a very large floating crane. Any information you can give me would be much appreciated.

Andy stepped out 18 months ago and apparently hasn't come back.
