Navy,

Thanks for the link. I have seen my fair share of SSC and pitting, its scary stuff. Fortunately our environment is a fair bit less harsh than Thailand so we do not see the same level of problems that they do.

Just curious, but why stray from what you know works?
I regularly place different bolts in different parts of the island for research purposes. This is an ongoing project that I have been conducting for a couple of years now. I have a number of rocks sitting next to the ocean with a wide variety of bolts installed in them. I conduct long term studies on the suitability of different alloys of stainless steel and different types of bolts. After a certain amount time has elapsed I pull test them to see how strong they are.

There are conditions in which titanium is not necessary required. I am trying to figure out if we need to use Ti bolts on routes that are well inland. If we did not have to use Ti on inland routes we could halve our bolting costs for those routes. That is part of what my research is about. Currently it costs well over $100 to bolt a single route. So if we can safely use a less expensive alloy further inland, than that helps everyone.

So ultimately these bolts are just another in a long series of tests. I just want to make sure I prep them correctly to maximize their potential. These bolts seem promising which is why I am giving them special attention and taking the extra time to polish them and all the like.

But ultimately, Ti or 2205SS is the way to go for serious environments.
