All Sounds very intresting! I was thinking that It was thinking that SST 316 was the same as T 316. I'll continue to research more on this. Thanks for your help everyone. Regards, Hiram Design Engineer Spartanburg, SC

I believe SS and SST are both abbreviations for "Stainless Steel" Like slang, one might say There is, at least in theory, the original AISI 316, with the UNS number S31600 Chemistry limits include 0.08%carbon maximum Most commonly available is the low carbon version, 316L, UNS S31603 Carbon is limited to 0.030%max, for better corrosion resistance in welded joints A hard-to-find version is 316H, S31608, meant for high temperature use. Carbon is specified as a range, 0.04--0.10. The higher carbon is needed for strength at high temperature. In fact, sheet and plate will usually be dual certified as 316/316L (common) or 316/316H (hard to find in distributor stocks) There is also a 316Ti, very uncommon in the USA, popular in Europe. UNS number S31635, a 316N, S31651, and a 316LN, S31653. This last might be available in full mill heat quantities, but none of these are commonly available from anyones' stock. Mo is specified 2.00--3.00 in all versions of 316. Because Mo is an expensive alloying element, it will rarely be found above 2.10%

Good question, this is referenced on this web resource (Engineers Edge). The "T" seems to be an AISI reference indicating "Tool Grade". The web page in question - /stainless_steel.htm needs updating.. Modified by Kelly Bramble at Mon, Feb 12, 2007, 08:44:44
