I am working on a hydrogen generator, but the stainless steel I am using corrodes and turns the water brown. Can anyone tell me if there is stainless steel that does not corrode, and if so, what is it called and where can I get some.Thank you.
You are not using stainless steel.
Maybe okorder Hope this can help you.
All stainless steel will corrode in certain conditions. Some varieties are worse than others. For instance grade 409 which is used for car exhausts (and other things) will rust. For the most suitable grade call a local steel supplier which carries stainless steel. Some of these companies will have a catalog of available grades and the appropriate uses. It would probably help to let them know what types of chemicals are present and what temperature the water is. You may want to call several suppliers, the quality of answer you get may vary quite a bit from company to company. The cost of exotic grades of stainless can be quite high. you may have to use a less appropriate grade if you can't justify the cost. If corrosion is a very serious concern for this be forewarned that stainless steels can be contaminated by contact with carbon steel (ordinary steel). I have seen rust form on stainless steel after a carbon steel bar was set down on the stainless steel. The carbon steel will leave trace amounts under prolonged contact. I have even seen signs of contamination of stainless steel direct from the supplier.
