SS316 has a 0.08% max carbon content while SS316L (UNS S31603) only has a maximum 0.03% carbon content. 316 stainless steel has a max carbon content of 0.08%. With a higher carbon content, 316 is more likely to experience weld decay. The "L" stands for "low carbon" content. In other words, 316L is more resistant to intergranular corrosion. In case of Duplex and Stainless Steel 316, there is no clear winner. 316 stainless steel has a max carbon content of, . The key difference between standard 316 stainless steel and SS316L is the composition, 316 contains more molybdenum than 316L, which results in increased resistance to pitting and crevice corrosion and better protection when exposed to high-chloride chemicals and acids. Both grades hbspt.cta._relativeUrls=true;hbspt.cta.load(1629394, '356e76f2-b8ec-4433-817d-3187fd3ec8f0', {}); (Editor's note: This article was originally posted in July 2016 and was recently updated.). The … 316L stainless steel has better resistance to carbide precipitation than 316 stainless steel and it can be used in the above temperature range. Metline Industries supplies high quality Duplex stainless steel 2205 rods and bars, as well as Stainless Steel 316L stainless steel bars and rods. I am not aware that there is a significant difference in the corrosion resistance of one over the other. The main difference between AISI 316 (1.4401) stainless steel and AISI 316L (1.4404) stainless steel is the carbon content. 316 stainless steel has more carbon in it than 316L. If you're not sure which type of steel is best for your project, here's the biggest thing to remember: if your project requires lots of welding, 316L is a better choice off the bat. Cost is very similar, and both are durable, corrosion-resistant, and a good choice for high-stress situations. Since pricing and corrosion resistance are both equally important when deciding a grade for a particular selection. What's the difference between 316 vs 316L stainless steel? Performance-wise, 316L is better than any other stainless steel for very high temperature, high corrosion applications. The upper limit of C content of 316 is 0.08%, and the upper limit of C content of 316L is 0.03%. (It describes its composition of 18% chromium and 8% nickel) 316 stainless steel - also called marine grade stainless steel. 316and 316L stainless steel pipe are both the low carbon steel pipe and differ from the content in the element of Carbon.Standard for ASTM A312、A312M、ASTM A213,A213M、ASTM A240;JIS G 4304、JIS G4304,JISIG4303. Note these are the same materials as SS316 and SS316L, as well as AISI 316 and 316L. Grade 316L, the low carbon version of 316 and has very high immunity from sensitization (grain boundary carbide precipitation). However, this is only an issue if the metal needs to be welded over a period of several minutes or it's heated to temperatures between 425-815º C. 316 Vs 316L Cost 316L stainless has a max carbon content of. If you're looking for highest durability, 317 and 317L have a higher molybdenum content, which increases their overall corrosion resistance. If you are the site owner (or you manage this site), please whitelist your IP or if you think this block is an error please open a support ticket and make sure to include the block details (displayed in the box below), so we can assist you in troubleshooting the issue. 316 stainless steel need to anneal in the temperature range of 1850-2050 o C, then anneal and cool rapidly because it cannot be hardened by overheating. Welding Stainless Steel Grade 316L is a low carbon Austenitic chromium-nickel stainless steels with corrosion resistance same as type 316 however with resistance to intergranular corrosion following welding. If you're looking for a cheaper material, 304 and 304L are physically similar to the 316s (slightly less durable) but cost a little less. 316 vs 316L Stainless Steel: What's the Difference? The entire 300 series of austenitic stainless steels are well-known for their strength and long lifespans. The main difference between AISI 316 (1.4401) stainless steel and AISI 316L (1.4404) stainless steel is the carbon content. No matter how you slice it, the "L" is the difference. The Difference Between 316 and 316L Stainless Steel The difference between 316 and 316L stainless steel is that 316L has a.03 max carbon and is good for welding whereas 316 … Need both welding AND forming fabrications? 304 stainless steel- also called 18/8. However, 316 can be annealed to resist weld decay if you're set on this grade. Fact 1: There’s no visible difference between grade 304 and 316. How do you remember which is which? 316 has.08 Max carbon content while 316L has a.03 Max carbon content. 316L stainless steel is … Stainless steels, thanks to their chemical composition, are metal alloys, which are naturally corrosion resistant.. AISI316L stainless steel, known as 1.4404, is different from AISI 316 (1.4491) stainless steel because it has less carbon inside.The “L” actually stands for “low carbon” content. It is extensivly used in the oil and gas and chemical industries for its cost effective corrosion resistance and ease of fabrication. The low carbon content of 316L stainless steel means it's slightly more weldable than grade 316. In other words, 316L is more resistant to intergranular corrosion. This is easy to remember, as the L stands for "low." The main difference between 316 and 316L stainless steel is the level of carbon content, weldability, corrosion resistance and mechanical properties. The L in 316L stainless steel denotes a lower carbon content. So, you can’t identify them just with the naked eye. But even though it has less carbon, 316L is very similar to 316 in almost every way. 316L has a Low carbon content. 304 vs. 316 vs. 316L stainless steel properties 304, 316 and 316L stainless steel formulas are austenitic, a term classifying the steel’s crystalline structure. However, this is only an issue if the metal needs to be welded over a period of several minutes or it's heated to temperatures between 425-815º C. If you're choosing materials based on price, the lower carbon content of 316L doesn't make a big difference. Differences Between 316 and 316L . alliantmetals.com/whats-difference-316-316l-stainless-steel/, Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36. Talk to your manufacturer about which material is best for your project. This structure is achieved via heat treatment at very high temperatures followed by quenching—a rapid cooling process locking the structural characteristics in … This is the primary difference between the stainless steels. 316L is easy to fabricate, and is used often in construction, marine, and infrastructure industries due to its durability. This leads to a variety of differences in its machinability, weldability, and corrosion resistance. 316L stainless has a max carbon content of 0.03%. Overall, both steels are highly durable, corrosion resistant, and perform well under high stress conditions. Easy peasy. The difference between 316 and 316L stainless steel pipe. Specifically, the carbon quantity present in AISI 316L stainless steel must be ≤ 0,03. It's the carbon content. The difference between 316 and 316L is the amount of carbon that is in the material. The "L" stands for "low carbon" content. Access from your Country was disabled by the administrator. With a higher carbon content, 316 is more likely to experience weld decay.
