316 SS VS. 316L SS - Metal and Metallurgy engineering - Eng-Tips
WEBunclesyd (Materials) 20 Jan 04 09:32. Less Carbon in the 316L usually relates to lower allowable values in the strength levels. But the dual certified material should come with an MTR with the actual values of both tensile and yield. Several innovations in the production of S/S has allowed the producers to Dual Certify S/S.
Corrosion rates of 316SS in different % of Sulfuric Acid
WEBDec 4, 2007 · turduckin, Just indicative, 20% sulphuric acid at 20 deg C would cause a corrosion rate of over 100 micrometers/year on SS 316 and over 1000 micrometers/year at 80 deg C even in small concentration (1-5%). But again, the internet is overflowing with free information on corrosion resistance of most type/grades of …
SS 316 Vs 316L - Steel and Stainless engineering - Eng-Tips
WEBJul 18, 2007 · The Corrosion resistance of SS 316/316L in seawater, mostly pitting/crevice corrosion, is due to the presence of Mo in concentration between 2-3%. The L means that the carbon is below 0.03% and this make difference when you have to weld it. Lower concentration of C means no problems of sensitization and following intergranular corrosion.

WEBDec 19, 2018 · RE: A564 17-PH vs 316SS. EdStainless (Materials)20 Dec 18 21:51. I can't share test data because it belongs to a customer of ours. By the time you cold draw 316 to reasonable strength (110ksi min yield, 150ksi min UTS) in order to get properties similar to 17-4PH H1150 you have very low ductility (<8%).

WEBDec 22, 2004 · The CF-8M is a cast version of wrought AISI Type 316 SS. As far as replacement, it depends on your specific application. There are a few similar material references that you may be able to find. In addition to AISI you will find cast type 316 Stainless Steel references as ASTM A351 Grade CF8M or ASME SA351 Grade CF8M. CF8M is listed as UNS S31600.
304, 304L versus 316 in corrosion resistance against Nitric Acid
WEB4. Surin (Materials) 29 Sep 99 01:36. Nitric Acid is a specific environment for intergranular attack (IGA) on sensitized austenitic grades. As such the low carbon and stabilized grades are used i.e.,304L ( instead of 304), 321 and 347. A nitric acid grade (NAG) of very low carbon, silicon and phosphorus to improve resistance to IGA is available ...
Any Difference between SS316L and dual certified SS316/SS316L?
WEBJan 29, 2021 · We never spec 316L, always 316/316L (i.e. dual certified). One main issue of plain 316L is you want find it (easily) for most common items, like pipe, flanges, etc. The other advantage of dual certified is increased strength, vs reduced sensitivity to e.g. IGC. Huub - You never get what you expect, you only get what you inspect.
304L vs. 316L Economics - Pipelines, Piping and Fluid Mechanics ...
WEBNov 24, 2004 · Phosphoric Acid is quite often used for cleaning applications, and I'm pretty sure that this requires 316L. 304L is still slightly cheaper for pipework than 316L , but there's not much in it. As Montemayor says 316L is standard for exchanger tubing so is actually cheaper than 304L. Sched 10 should be satisfactory unless you expect high ...
