Re: premature rust?
This is just a bunch of none sense.
I've worked in the steel industry for the past 30 years. We make the instruments that measure the materials composition, shape, thickness, flatness and atomic structure in the steel mill as it’s being produced. We also do the ladle analyst before the materials come out of the ladle so I see the quality on the entire process.
The quality of materials being made today makes those in the past look primitive. To insinuate that corners are being cut in the quality of the materials is showing ones ignorance of the materials and the industry.
As for the Chinese steel industry, the Chinese buy nothing but the best when it comes to steel making equipment. We sell more high end analytical equipment to China than the rest of the world combined so that should tell you something about China's commitment to steel quality.
Most “rusting” of stainless is caused by the materials not being passivated correctly after fabrication. When stainless is fabricated particles of Fe can become imbedded in the materials from the machine and grinding processes. Good fabrication practices dictate the parts be passivated, (dipped in a acid cleaning solution) to remove the Fe from the materials. If this process is skipped or done improperly you’ll get surface rust on what is otherwise good stainless materials.
What this guy is experiencing with his boat is something different. Stainless steel is stainless because the materials reacts with the oxygen in the air to form a layer of oxide layer on its outer surface. You take away the air, as in water trapped between the surface of the material and the surface of the boat, and the end result is “staining”. This is the reason why deck hardware is “bedded” and should be rebedded when this condition occurs.
This problem is easily resolved by removing the hardware in question and using a bedding material between the hardware and the fiberglass on the boat to keep water from getting between the two surfaces..
Thanks for the compliment. The standard of replies here goes from one extreme to the other. Yours would have been a good one, but you ruined it with your opening statement.
I am closely connected to the Airline & Automobile industry and also have many friends here who maintain & procure equipment for commercial airlines (Lufthansa Technik AG) for a living. I also have a very old friend who's family (third generation) is in the business of suppling the aviation industry (both U.S. Military and Commercial) in the States with fasteners.
All say that there is a growing problem of counterfeit & false marked products that they are receiving is reaching proportions they have never seen before, and they are coming for the most part, out of Asia. If the airline and automobile industries are having sourcing problems, then so is the boating industry.
Suppliers are not local anymore, and procurement is made using the lowest bidder method. The lowest bidder is unfortunately often long gone when the problems start to occur, and quality problems are occurring.
I didn't say the Chinese can't produce quality, they can compete with anyone in any sector now. It is a matter of quality control that is a problem, and when budgets are cut, these controls are often cut along with everything else.
Nor did I say there are not solutions, to rust stains, on a one month old boat. I am saying it shouldn't be the case.
What woulda, shoulda, and coulda been done is all good and fine, but ...
