What is the difference between 316L and 316LN?

The main differences between 316, 316L and 316LN lies in their chemical composition. The “L” indicates lower carbon content, while the “N” in 316LN points to the higher nitrogen content.

What is 316 LN?

316LN (UNS S31653) is a lowcarbon, nitrogen-enhanced version of Type 316 molybdenum-bearing austenitic stainless steel. The Type 316 alloys are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as Type 304.

What is the difference between 316L and 317L?

317L has excellent corrosion resistance in a wide range of chemicals, especially in acidic chloride environments such as those encountered in pulp and paper mills. Increased levels of chromium, nickel and molybdenum compared to 316L stainless steel improve resistance to chloride pitting and general corrosion.

What is L in 316L stainless steel?

316/316L Stainless Steel: The ‘L’ Designation The L denotes the low content of carbon in the steel. 316L is best known among fabricators for being resistant to cracks after the weld process is completed. This makes 316L the preferred choice of fabricators who look to build metallic structures for industry applications.

What is 316 SST material?

A popular grade of stainless steel is stainless steel 316. Stainless steel 316 is generally composed of 16 – 18% chromium, 10 – 14% nickel, 2 – 3% molybdenum, and about 0.08% carbon. The added molybdenum makes this grade more corrosion resistant than the other types.

What is Ln in stainless steel?

Introduction. Stainless steel grade 316LN is an austenitic type of steel that is a low carbon, nitrogen-enhanced version of grade 316 steel.

What is ASTM A240 Type 316L?

In ASTM A240, type 316 and 316L is a chromium nickel austenitic steel, Element molybdenum addition can enhances corrosion resistance of stainless steel, which is the main factor that 316/316l is more corrosion resistant than 304/304l.
