Hey @grok, Found this at titanum plant.. Not sure why ball point pens would be dangerous here.. Do you have any idea about this???

Ballpoint pens are banned at titanium plants (especially sponge or aerospace-grade melting) because the tiny writing ball is tungsten carbide. If it falls out or contaminates the melt, it creates hard brittle inclusions that can cause structural failures in critical parts. Strict quality control prevents even that small risk.

Is there any case happened when someone took ball pen with them and something mis happened

The problem is the tiny ball in the tip of many ballpoint pens, which is commonly made from tungsten carbide. Tungsten has a melting point of about 3,422°C, while titanium melts at only about 1,668°C. So if a ballpoint penor even just its tiny ball gets into material being melted

they lost one pen and escalated this into a national security threat

they ban ballpoint pens cuz ink leaks could contaminate the plant and mess with sensors.

I mean... when they ban items there's generally a good reason... right?

I’m in my 60s…. Worked in an office for decades….. Used ball point pens all my life…. Never, not even once, saw that little ball come out of a pen. Ever….

Your jeet ass stole this image as engagement bait. For those actually interested, the reason they are banned is if a pen falls in the metal in the ball can create impurities in the titanium for important aerospace components reddit.com/r/whatisit/s/Kpnm…

Some aerospace companies also invoke restrictions on anything to do with silicon. No silicon oils, no silicon adhesives, etc.

I used to audit and work with a titanium plant in Wales. Yes ball point pens were banned. There are several instances of similar things in aerospace manufacturing.

In the Skunk Works book, Ben Rich talks about all of the weird ways titanium can be affected. Eg cadmium coated tools make titanium brittle

Nickel coated wrenches around aircraft turbine engine maintenance and assembly immic is a no-no. Blackened tools only. The Nickel rubbing off in the turbine area could cause problems as well.

Well, it's, you know, if you're carrying a ballpoint pen in your top pocket and it falls into the melt or something, so if the whole pen falls out of your pocket somewhere and ends up in the melt, the steel from the pen will melt. It's titanium, and then the only thing remaining will be the tungsten carbide ball, which could cause contamination. The ball's not going to fall out of the pen, you fucking idiots.

Tungsten balls? How do they even get their tiny legs apart?

Probably not because writing with a ballpoint is inherently dangerous. In a titanium plant, the concern is usually contamination/FOD and, in some areas, ignition risk from metal components around combustible titanium dust or fines. Approved non-metallic writing tools are often safer.

This is the dumbest engagement farming ever. As someone who has been thru site safety orientation to work at a titanium plant, this is common knowledge there 🙄

There has to be a story there... how would you like to be the guy who accidentally dropped a pen into a melt and caused a critical system to fail killing possibly millions of innocent people
