Sharpening hazard

[GregManning]

There are many, many types of stainless steel alloys.

Some are more magnetic than others. But the steel (Fe = Iron) is always magnetic; it depends on the alloy ratios.

Many people think that stainless steels won't rust. Not correct. Many will rust, in the right corrosive conditions.

Simple answer is yes John. Complicated answer is most times. Without getting into a metallurgical discussion 300 series are not magnetic. However that is a broad statement.

I had just remembered something about austenitic vs. ferritic

Exactly, well other than heat treating, machining sometimes, and forging but that is a whole discussion for metallurgy majors. We have come about as far as I feel competent in attempting to have a discussion about, lol.

Metal is cool stuff! It's nice to have people like you around to answer questions so I don't have to study the subject in depth myself.

Yeah monkeylove, you gotta write an article about metal properties for the new treebuzz article project. That would be really awesome. It was really helpful when you chimed in on the bulldog bone temp question.

While I'm flattered Mac and would certainly contribute anything I could to this forum there are far smarter people than me on the subject.

 

[macswan]

Yeah, but where?

So Mac, what can we learn from this?
Only thing I can think of is, maybe take the air hose and blow everything off real well when we're done?

When I was working at the tech college I became friends with the fluid power/hydraulics instructor. On the first day of class every student was told that they would be kicked out of the class if they used an air hose to dust themselves or anyone else.

Their is a high probability of even low air pressure pushing air through the skin and into the blood stream. This air bubble will move along and could become a clot. The result could be a stroke or other serious circulation injury/death.

Don't do it.

 

[GregManning]

That's why all current "OSHA Approved" compressed air nozzles have many side vent holes near the end

I might be a little late in the derail with the MRI talk, but I just did a job for a acquaintance who's wife is undergoing emergency brain surgery. She has a cochlear implant, and the doc's sent her in for a MRI... Ooops, I guess I didn't read your file clearly enough....

Don't do it.

Just like with everything else in this world, it takes a little common sense to remain safe. Been using the air hose without incident for ~56 years and will continue to do so. I'm comfortable that used properly, it is safer than climbing trees, using chainsaws, driving, going down stairs, etc.
