mogandave Posted December 2, 2014 Share Posted December 2, 2014 (edited) @jikwan, @h90 I work at a multinational steel pipes and components stockist/distributor in Thailand. (we're one of the biggest players worldwide) I can get you 316/L plates or any other grade you desire. From an entire sheet to only a small cutting. You name it. Grades more exotic than 316/L will need to be imported though, simply as there's no availability in Thailand. (At least not of reliable quality). If you know exactly what you want (size, quantity, grade), please send me a PM and I can assist you with an offer. I think all stainless is imported. Nope at least 3 or 4 mills that I know of that produce stainless in Thailand Some of the more exotics are imported ie your duplex and super duplexes for example I buy a fair amount of stainless, and while I would love to be proven wrong, I think you are incorrect.

mogandave Posted December 2, 2014 Share Posted December 2, 2014 As far as differentiating between 304 & 316: Most sheet nowadays is marked with continuous "inkjet" type labeling showing the manufacturer, the material grade, and the heat number. You can also buy inexpensive grade specific reagents that will change color to indicate grade. How much and how thick? The colour reagents are not a reliable or definitive way of identifying the grades, without subjecting a sample to a proper lab test, the only portable way which is accepted by industry is a PMI (positive material identification) which is a portable instrument which can identity the constituent elements and percentages in the alloy and based on the percentages primarily of nickel, chrome and a few others can determine the grade based on ASTM classifications of the various alloys. Assuming they are fresh, the reagents are fine for differentiating between 304 & 316L, and they only cost about US$20. What does a PMI cost?

jikwan Posted December 2, 2014 Author Share Posted December 2, 2014 souty,, you sure yhour not a welding inspector,,,lol good stuff mate,, as for the OP, if your near samut prakarn, find a company called ,shape solids handling and process engineering, there on google, i was operations manager there, pop in there they make convayers ect for the food industy, they would sell you a bit of 316L ask for mike the managing director hey jake, if i cant get it closer to home i ll take a hike down there. sounds like a dead cert. thanks 1 Link to comment Share on other sites More sharing options...

This is indeed the only way which is acceptable in the industry. Actually, all mills producing a stainless product will conduct the PMI test already, which is mentioned on the mill test certificate. You only need to use material which is really coming from that (reliable) mill. Doing it again in Thailand is no problem, only you will be asked a minimum charge usually. Or you should find a friendly guy who will do it for you for free. If you're testing many pieces, it's only 5 USD per tested point. (1 point per piece is sufficient ) Link to comment Share on other sites More sharing options...

tutsiwarrior Posted December 4, 2014 Share Posted December 4, 2014 (edited) if you are selecting 316L for the corrosion resistance alone and not strength the are other non-ferrous materials that can be considered and that are more easily obtained...most industrial water treatment plant that I'm used to working around doesn't have a lot of stainless steel, mostly plastic like PVC, GRP and etc...

NeverSure Posted December 6, 2014 Share Posted December 6, 2014 When I want scrap sheet metal I go to a shop that makes things from sheet metal. I mean the type of shop that makes one-off things for industry such as commercial range hoods or anything else that's needed. They always have scraps and they always know what it is. Sometimes if it isn't a really big piece they just give it to me, but usually they sell it by weight. It never costs very much. Link to comment Share on other sites More sharing options...

You would expect only to see possible leaching at very high temperatures, if your looking for very good cleanness would suggest you do a pickle and passivation on your stainless, which will remove any surface contamination and "beef up" the protective chrome oxide layer on your material I suspect your biggest problem is keeping things gas tight seeing as your using hydrogen Link to comment Share on other sites More sharing options...
jikwan Posted December 6, 2014 Author Share Posted December 6, 2014 hi southy, device im making produces gas from water 2 plates. posative wire (from battery/mains) is connected to 1 plate, the neg to the other plate. put both into a container of water and they produce hydrogen and oxygen gas if you want much more gas bring the plates very close together if you want more than that increase the volts/amps. can get it so that it billows gas (50 liters per min+) thats when the plates get hot i want moderate amount--the plates would only get warm put a lid on the container with an outlet pipe---you can then direct the gas to wherever you like. some mechanics can run their cars on this gas. exclusively-no petrol added anyway, the gas from theplates goes into another sealed container filled with water, it rises through the water to the surface.that gas is cleaned-any impurities should remain in that water this gas can be added to your drinking water and theres many reports of it being beneficial to your health collodial silver is made in the same way, instead of using ss youd use pure silver. but with the silver water- you drink it without 'cleaning' it. it contains nano silver and these particles give health benefits if low grade ss is used the plates get dirty and the water gets dirty too copper plates produce a lot of gas but the plates get covered with gunk and water is very dirty within minutes https://www.google.com/search?hl=en&site=imghp&tbm=isch&source=hp&biw=1024&bih=548&q=hho+wet+cell&oq=hho+wet&gs_l=img.1.0.0l3j0i24l3.1680.5597.0.10792.7.7.0.0.0.0.791.1379.5-1j1.2.0.msedr...0...1ac.1.58.img..5.2.1379.Bey_RfB4DLc http://www.naturalnews.com/038579_colloidal_silver_healing_water.html Link to comment Share on other sites More sharing options...

tutsiwarrior Posted December 6, 2014 Share Posted December 6, 2014 (edited) I agree absolutely...and probably the most useful post in this tread... it's been years since I did any DIY and I was a Volkwagen freak back in the 70s...I could wander around a VW breaker's yard just looking at stuff all afternoon... wanted to have a rebuilt long block available to pop into my '66 van when needed..but those were poverty days and I never had a garage available to keep it in...too busy surfin'... (tutsi! what's this greasy piece of junk doin' in our living room??!!...' 'aw, if I leave it outside it will get stolen...' lowlife, low rent Venice, CA but just a couple of blocks from the beach...) right on, NeverSure...
