Does the Stainless Steel E316 resist seawater and Temp?? 5

[finder01]

My name is Bassam, i am an industrial engineering student, meanwhile i am in a research about Stainless Steel.<br>the main subject of this project is how many years could the Stainless Steel live in seawater, particulary the Stainless Steel E316.<br>i will be so glad if you let me know whether this kind of material could resist seawater, and humidity??? could the properties of this material remain the same under temp. 50 c<br>???<br>if this isnt the proper material to use under seawater, could you please recommend me of the best material???<br><br><br>Awaiting forward to your kind reply.<br><br>BAssAM

Any body knows the price difference between 316 (or 316L) and 6% Mo alloy? Where can I find the cost-benefit analyse between those two kind of materials?

As a general rule, the 6% Mo alloys cost approximately three times the price of the equivalent form in 316L. The AL6XN Technical Data and Fittings Catalog at

http://www.al6xn.com/litreq.htm

includes an extensive listing of corrosion rates of 316L, AL6XN, 2205 duplex, C-22, and other special alloys in various acid and alkaline evironments. The booklet can be downloaded in pdf format.

I recommend that you read the following paper.

If you are looking for information on AL-6XN or 2205 duplex you can find extensive information on

http://www.rolledalloys.com

in pdf format for download. It also allows you to get relative pricing between these alloys and 316 stainless online.

As far as seawater is concerned 6% moly alloys like AL-6XN are excellent for resisting SCC, pitting, and crevice attack. 2205 is questionable in seawater although in higher velocity situations we have seen duplex 2205 used for things such as seawater pumps. In reality for seawater a superduplex like 2507 is much better suited to resist corrosion than a 2205.

What does 254 SMO stand for?
What types of welding processes can be applied to
weld piping elements?

Thanks,

This is for the people who wanted to know if there was a test to distinguish between 304 and 316

You'd distinguish them on the basis of Mo content

the following webpage details a kit which can do this

http://www.koslow.com/1542c.html

which references ASTM E 1476-95

probably not that simple, but if you can find a way to dissolve some of the sample up and then detect molybdenum using a chemical test, sounds like you'd be set.

hi murz

i have a similar problem with a heatexchangers we have to select another material for the tubes and we where thinking in a ss 316 L for use in a sea water but as see in this tread is not going to work can you send me a copy of the pages of the manual to my e-mail is heatexg@latinmail.com i apreciate all the help
