I thought Lance had virtually proven H1 to be rust proof in his extreme use (?). This is the first time I’ve ever seen a corrosion example. I mean I’ve seen the stuff attribute to contaminated grinding equipment.

Thanks a lot @Bloke. :rolleyes: I guess next you’re gonna tell me rabbits don’t lay eggs? :p ;)

There are a lot of things that can go wrong with how the steel is made that can reduce the amount of free chromium locally, even in H1/LC200N (remember, they're not powder steels). What's rust proof on paper and for 99% of users, can rust on one unlucky fella without doing anything abusive.

At the end of the day LC200N has around.. 15% chromium? Which translates to 13-14% free chromium in the steel + N, Ni and Mo which also help. Yet approved marine stainless steels have double that, close to 26-28% chromium, and those can also rust under certain conditions.
Chlorine is a b-word lol, it shouldn't surprise anyone that these steels can corrode. A minimal amount of care should be taken as with all tools, but what happened to this Spydiechef user is NOT normal and it's definitely a problem if the steel appeared to rust so fast.

We've been making "extremely corrosion resistant" models for many years and we ares still learning much. Eg: we learned that the Gulf after the oil spill had different effects than other salt water areas. We're learning about Galvanic reactions. We're learning about different heat treat effects. So we're consistently trying to produce models that best serve the needs of those in "Caustic" environments, The learning process continues.

Each time we add a new material, like LC, the game changes.

This particular model seems to have a steel ball bearing. Could be older stock? Sharkfisher can send it to us for a "look-see"?

I never would have thought of that, but it makes sense that such a concentration of oil would change the chemistry of the sea water in the area. Thanks for sharing that tidbit.
