Type 316L stainless steel is an extra-low carbon version of the 316 steel alloy. The lower carbon content in 316L minimizes deleterious carbide precipitation as a result of welding. The lower carbon content in 316L minimizes deleterious carbide precipitation as a result of welding.
AISI 316 and 316L are US steel grades, SUS 316 and SUS 316L are Japanese stainless steel grades. The main difference between 316 vs 316L stainless steel is the level of carbon content, SS316 has a 0.08% max carbon content while SS316L has a 0.03% max carbon content.
The differences between a 316L and a 316 straight grade are two-fold both in chemistry and mechanical properties. The L grade has a lower maximum carbon limit and the straight grade has increased mechanical properties.
316 / 316L are austenitic stainless steels that contain molybdenum, which increases their resistance to many chemical corrodents and marine environments. 316L is an extra low carbon version of 316 stainless steel. These materials are more resistant to general corrosion and pitting/crevices than conventional austenitic stainless steels.
AISI 316 stainless steel is one of the most widely used austenitic stainless steels. Due to the addition of Molybdenum (Mo), it has a great improvement in corrosion resistance and high temperature strength. 316L stainless steel is the low carbon version of AISI 316.
In comparison, the SS AISI 316 boasts better resistance to chloride-rich conditions than the typical SS 304 thanks to the molybdenum addition. Uses for SS AISI 316. Also known as surgical stainless steel, marine steel, 316S16 (as per the British Standard), the SS 316 is an austenitic chromium-nickel alloy. As a consequence it:
316L is the low carbon version of 316 stainless steel. Covered in thsi document are the physical and mechanical properties of 316L stainless steel. Other areas such as heat treatment, welding, machining, hot and cold working, hardening, work hardening and applications are also outlined.
Stainless Steel 316 - Alloy Composition Stainless steel type 316 is part of a family of stainless steel alloys (301, 302, 303, 304, 316, 347). The 316 family is a group of austenitic stainless steels with superior corrosion resistance to 304 stainless steel.
General Properties. Alloy 316/316L is molybdenum-bearing austenitic stainless steel. The higher nickel and molybdenum content in this grade allows it to demonstrate better overall corrosion resistant properties than 304, especially with regard to pitting and crevice corrosion in chloride environments.
ApplicationsAlloy 316/316L (UNS S31600/ S31603) is a chromium-nickel-molybdenum austenitic stainless steel developed to provide improved corrosion resistance to Alloy 304/304L in moderately corrosive environments. It is often utilized in process streams containing chlorides or halides. The addition of molybdenum improves general
Types 316 and 316L Stainless Steels exhibit better corrosion resistance than Type 304. They provide excellent pitting resistance and good resistance to most chemicals involved in the paper, textile and photographic industries.
Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. It has excellent forming and welding , 316 and 316l stainless steel composition
316/316L STAINLESS STEEL Product Description Type 316L is an extra-low carbon variation of Type 316 that eliminates harmful carbide precipitation due to welding.

Stainless Steel 316Ti is referred to as the stabilized grade of the 316 types, and also one of the two 316 stainless steels that is recommended for higher temperature situations. This grade contains a small amounttypically only 0.5%of titanium.
316 and 316L are austenitic alloys, meaning that these stainless steel products gain corrosion resistance from use of a nonmagnetic solid solution of ferric carbide or carbon in iron in the manufacturing process. In addition to chromium and nickel, these alloys contain molybdenum, which also makes them more corrosion resistant.
Differences between 316 and 316L stainless steel. 2002. A. 316 and 316L differ only by the amount on carbon in them. As I understand it, 316 L has lower carbon such that when welded the chromium carbide that forms does not deplete the chromium to the point where the corrosion of the stainless is deleteriously impacted.
The difference between 316 and 316L stainless steel is that 316L has a 0.03% maximum carbon content by weight while 316 stainless steel had a 0.08% maximum carbon content. Both 316 and 316L also contain some chromium, nickel and molybdenum which make both 316 and 316L stainless steels especially corrosion resistant.
1.4404, 1.4401, AISI 316/L - application and specification. Austenitic stainless steel is resistant to intergranular corrosion, used mainly in environments containing harmful chlorides, acids and urea. 316/316L is the basic grade from the CrNiMo group with Molybdenum, the addition of which significantly increases the resistance to pitting and crevice corrosion of steel by 2-3 times.
316L Stainless Steel. 316L stainless steel is defined by its low carbon content: no more than 0.03% carbon. In general, its composition is between 16-18% chromium and between 10-14% nickel (as well as trace amounts of manganese, silicon, phosphorus, sulfur and nitrogen). The number 316 refers to a reference number assigned by SAE International, a standards organization that serves the automotive and aerospace industries.
316 & 316L Stainless Steel. Austenitic 316L and 316 stainless steel alloys are highly regarded for their numerous beneficial qualities. Due to their high chromium, molybdenum and nickel contents, these two types of stainless steel alloys have superior corrosion resistance and are highly suitable for marine applications.
Stainless Steel 316 / 304 vs 316 L / 304 L. As American Iron and Steel Institute (AISI) basic grades, the only practical difference between 304 / 316 and 304 L / 316 L is carbon content; the [L] means the lower carbon content. The carbon ranges are 0.08% maximum for 304 and 316 and 0.030% maximum for the 304 L and 316 L types.
An example of a building in which these properties are exploited is the Art Gallery of Alberta in Edmonton, which is wrapped in stainless steel. Type 316 stainless is used on the exterior of both the Petronas Twin Towers and the Jin Mao Building, two of the world's tallest skyscrapers.
Types 316 (UNS S31600), 316L(S31603), 317 (S31700), and 317L (S31703) are molybdenum -bearing austenitic stainless steels which are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as Type 304.
316 also contains silicon, manganese, and carbon, with the majority of the composition being iron. A major difference between 304 and 316 stainless steel is the chemical composition, with 316 containing a significant amount of molybdenum; typically 2 to 3 percent by weight vs only trace amounts found in 304.

1.4404 (316L) Bar and Section. Stainless steel types 1.4401 and 1.4404 are also known as grades 316 and 316L respectively. Grade 316 is an austenitic grade second only to 304 in commercial importance. 316 stainless steel contains an addition of molybdenum that gives it improved corrosion resistance.
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.
Testing of Stainless Steel 316/316L Tubing All SS 316/316L seamless tubing are subjected to hydrostatic test, eddy current test, chemical and mechanical tests during the various stages of production. Marking & Packing of Stainless Steel 316/316L Tubing Marking on all pipes is as per the predefined rules in the specification.
316L stainless steel is non-magnetic austenite steel. It has low carbon content as compared with 316 material and thus having all the qualities of 316 grade it can also be welded at higher gauges as it does not weld decay due to lower carbon content.
