Marking of Stainless Steel and Titanium
Marking of Stainless Steel and Titanium
(OP)
Hi folks,
I have received a question from one of our inspectors relating to the use of marker pens on Stainless Steel and Titanium. Can anyone please advise if there are any standards relating to good practice etc when using markers on these materials. In particular, are low chloride markers OK for these material groups.
To add further information, the products will be seeing service in the chemical industry at temperatures of up to 350 deg C.
Many thanks for any advice or help you can offer.

never known any problem with chloride containing markers on titanium.
RE: Marking of Stainless Steel and Titanium
Great references and examples! I am going to save it.
I also believe their is a SHARPIE that may meet halogen ppm limitations.
I am also interested in any more information pertaining to halogens on Titianium and sulphur on Nickel Alloys.

Here is a little information on the use of halogenated solvents on titanium. There is a very good paper that discusses the cracking of Titanium in various media, that I can't locate. The paper probably came off Metadex.
Our experience with environmental cracking of Titanium was with 1280 hole spinnerets. To insure cleanliness of same we ran them through a enclosed vapor degreaser using Perclean. We had had no problem until the Perclean got a little old. We started seeing cracking of the ligaments between the capillaries and cracking like radial flange cracking on the periphery,

Thank you for sharing your knowledge and resources.

Never let anyone use a paint marker. period
I feel the same way about grease pencils and other similar 'china markers'.
RDT-F7-3T is obsolete, but there is no replacement. We still use it as a guide and have written our internal practice to meet it.
