Thank you for being precise when talking about metals and their corrosion products. Mech engineering background here. I appreciate when folks speak about metals in general, but especially from folks who are expert at it. 👍
Hey Chris. Most stainless steels are not magnetic. 300 series like you see in kitchen materials and see on some refrigerators are not magnetic. 400 series are magnetic. Something with ferretic and another name I can’t remember from my steel days.
Thank you Chris. I finally got time in my travels to see the video on the issue I raised. It's very good to see this being examined by a person with understanding of metals. When I get home I will look into it further, see whether it developed and whether it flakes off. All the affordable full metal body pens from China are brass, as far as I've seen. There is a theory that brass manufacture is subsidised by the Chinese government. But that's just a theory. Again, thank you for taking a look at this situation. I hope you enjoyed doing the research.
this is an informative video!... thanks... there is a lack of information about the durability of the materials that go into the production of fountain pens, and i hope you can continue to address this... for example, you mention plating... can you enlighten us on this subject?... in vintage pens one sees the brassing that occurs in say a parker parkette (a lower end pen) but which is less so in a parker vacumatic (a higher end pen)... and even some higher end pens have material that has not held up... for example, the celluloid in the more colorful eversharp dorics have been reported to show signs of deterioriation (grazing, i think it's called)... how can we determine in modern fountain pens, many of which are costly, that the makers are using materials that will last at least as long as the higher end fountain pens of the past... and how will these pens hold up under different types of cleaning?... i hope you and other reviewers that have expertise in this area can address this topic, as you have done so in this informative video... thanks again...
Thanks, I'll try to add to our pen knowledge. Many vintage pens used gold filled metal which is much thicker gold than plating & will hold up longer. It is difficult to evaluate modern pens for longevity. Besides the quality of components, environment can affect a Pen's condition. Exposure to sun light, water, heat, cold, etc. I've seen some vintage pens disintegrate sitting in a box of pens. Something is one or more pens in the box emitted a corrosive gas. Other pens look mint after over 100 years.
Thank you Chris . I worked in Automotive coatings for 30+ years and so i have a good understanding of metallurgy and polymer coating as well as metal coatings. Probably a better choice for the piston rod would have been high grade stainless steel (316) but brass is fairly corrosion resistant dependant on the grade. I don't see these rods corroding to the point it would affect the life of the pen that much , perhaps if you are using none neutral pH inks they may corrode faster , time will tell. Thanks interesting video.
Thank you Chris. I haven't experienced any problems with either of my Wing Sung 3013 pens. One of them has been in use for a month with Waterman Absolute Brown ink. The rod looks fine to me.
Thanks for the explanation. It really makes sense and gives me an idea of the quality of the build. I have a question about a kind of nib shim for lack of a better term. You demonstrated it a while back. It was something that had been included with one on your orders. I didn't know what the purpose was until you showed us. I used mine extensively from that day. Of course it is lost and I need another one. Any idea where those came from? Appreciate any help.
My higher end stainless steel tumblers and mugs are not magnetic or weakly magnetic when I use neodymium magnets. So I wouldn't be surprised if some of the metals that are in contact with the ink are of the same kind. Still cheaper than brass.
That was why I tested for magnetic steel. I did not observe any changes to the rod. Some did & called it rust. It is not, maybe pitting. All are forms of corrosion.
This was interesting. I had noticed that some of these Chinese pens did not have steel parts where I expected steel. I had not experimented with this particular pen. Fun that you did the same experiment with nibs that I did. I remember mentioning it in one of my videos and was told the same thing you mentioned about the nickel. (Maybe you're the one who mentioned it.) I wonder what the explanation of the rod actually is? Now I'm curious to try this on my Pilot 823!
My quests would be stainless steel for 823 rod, non-magnetic. Also should be very smooth polish, no pits like 3013. Conid uses titanium for their rods.
I got all five colours of 3013/013 and inked them with matching colour Sailor Shikiori/Pilot Iroshizuku and Pelikan 4001 inks. I'll let you know if I observe anything. Also, Chris, given the occasion, I'd like to ask you if you have tried to change the nibs of these pens and if yes what number size nib did you use ? (#5 ?)
@@korax67thank you for the reply. I was planning on getting 4 to use different inks simultaneously, I'll get one first to test it out. But overall would you say they are good pens?
@@billybob-xy5pt for their price it's a steal ! The fine nibs are very good. The built quality and the general feeling is absolutely positive. You won't be dissapointed, if you want to try this filling method. But be aware that it is not a pen that will last a life time like a metal Jinhao. Overall I didn't regret buying them at all.
Had to look up austenite - Found this: "Fundamentally, the reasons why ferritic stainless steels are ferromagnetic while austenitic stainless steels are not are quantum-mechanical in nature." Austenite stainless steels usually contain 8% or more nickel which is the main reason for being non-magnetic.
@@chrisrap52 Nickel doesn't cause the alloy to be nonmagnetic directlly, it simply enables the austenite to be stable at room temperature. Pure iron can also be austenitic and thus non-magnetic, it just has to be heated to ~1200°C (if memory serves), however once it cools it's phase will change back to ferrite. Edit: other alloying elements (like chromium) also stabilize austenite, Nickel and Chromium are simply the most abundant.
interesting subject i,m thinking it maybe crevice corrosion due to low grade stainless steel or coated brass rod being immersed in a low oxygen /slightly acidic enviroment ? en.wikipedia.org/wiki/Crevice_corrosion
Thanks for another nice video. However, not being magnetic to me means it is not common iron or steel that easily rusts. It cannot directly prove it is not iron or steel. Based on my experience on epitaxy tools, stainless steel for critical parts in my tools is very weakly or not magnetic. So I would say the rod can be made from a certain kind of stainless steel or simply other metal such as brass. Anyway, after seeing this test, i guess it is not likely that the rod becomes rusty easily.
Great info from an engineering pt of view. Enjoyed it.

Very educational and interesting especially for those of us who are in social sciences rather that in engineering. Thank you Chris.
Glad you checked this out with a magnet. I’m a little skeptical about some of the “metal “ threads and bands to. Thx for vid.
Glad I could help!
Thanks for this very informative exploration Chris.

No issues with any of mine yet (diamine inks). Do have small corrosion spots on the screw in the cap though.

Fantastic, informative video!
The screw that take the caps of the Chinese fountain pens to hold the clip always rust. I have exchanged several iron screws for plastic screws.
I ordered nylon screws that should fit. Will do a video if they work.
Really informative. Thank you.

Neodymium, manganese, cobalt, iron and nickel are magnetic. Three types of magnetism are ferromagnetism, paramagnetism and diamagnetism.
Thanks for clarifying. When a pen costs
But is it rust or just a bit of corrosion/pitting? Rust sounds scary.
That was why I tested for magnetic steel. I did not observe any changes to the rod. Some did & called it rust. It is not, maybe pitting. All are forms of corrosion.
@@chrisrap52 Thank you. I'll be ordering a Paili green and blue in F later tonight. I hope they turn out as good as yours did.

Did you by any chance check the rods in the wing sung 699?
Yes, no corrosion.

Steel doesn't have to be magnetic, it depends on the phase. Austenite/austenitic steel is non-magnetic and usually very corrosion resistant.

What Chinese pen would the nib out of my useless Penbbs 268 vac filler fit? Thx
PenBBS nibs are a #6 size. Moonman C1 & 660s use #6. Jinhao 450 & 750 also.
Es curioso que haya comentarios de corrosión.

I can’t remember the weight of this pen. I think brass may weigh more than stainless steel. If aluminum you probably can tell a big weight difference.

Anyway, after seeing this test, i guess it is not likely that the rod becomes rusty easily.
I use my visual examination to determine the rod is plated. Brass is the typical base metal used in these pens for plated parts.
Fascinating. I rate this video as a 9.9.
