AISI 316L<\/strong> is a fully austenitic stainless steel. AISI 318<\/strong> (duplex 2205), as its name suggests, is two-phase<\/strong>: its structure contains roughly half and half austenite and ferrite<\/strong>. That structural difference changes both the strength and the corrosion behaviour from the ground up.<\/p>\n

Nitrogen and low nickel<\/h3>\n

According to our datasheets, chromium rises to 21.00\u201323.00%<\/strong> in 318 while nickel falls to 4.50\u20136.50%<\/strong> \u2014 less than half the 10.0\u201314.0% of 316L. The high chromium forms the ferrite phase, and the reduced nickel supports it. The austenite phase is balanced not so much by nickel as by nitrogen<\/strong>: in 318 nitrogen is in the 0.10\u20130.22%<\/strong> range.<\/p>\n

Nitrogen does not only balance the phases, it also strengthens the material. The result is clear in the mechanical values: where the yield strength of 316L is 170 MPa<\/strong>, that of 318 is 460\u2013500 MPa<\/strong> \u2014 roughly three times as much. The tensile strength rises from 485 MPa to 700\u2013900 MPa<\/strong>.<\/p>\n

The ferrite phase also provides resistance to stress corrosion cracking<\/strong>. That is the point at which 316L is weakest in hot chloride environments; the duplex structure largely blocks that mechanism. The low nickel content also makes the material more stable against swings in the nickel price.<\/p>\n

Values are taken from our product datasheets; section thickness and the applied heat treatment regime change the result.<\/p>\n

Which one, and when?<\/h3>\n

AISI 316L is sufficient<\/strong> \u2014 food and pharmaceutical pipework, general process equipment, welded tanks and pipes, architectural applications. It is far easier to form and to weld; there is no need to watch the heat treatment window as with duplex.<\/p>\n

AISI 318 is required<\/strong> \u2014 pressure vessels, seawater lines, oil and gas process piping, paper industry equipment, structures working under stress in chloride environments. Because its strength is high, a thinner wall<\/strong> can be used for the same pressure; that reduces the total weight and, in most cases, the cost.<\/p>\n

One point to watch: duplex steels become brittle if they spend a long time in the 300\u20131000 \u00b0C range. 318 is not used in high-temperature applications; austenitic grades are preferred there.<\/p>\n

A step up<\/h3>\n

For more aggressive chloride environments there are the super duplex grades AISI F53<\/a> and AISI F55<\/a>. If you want to raise corrosion resistance on the austenitic side, see our AISI 316L \u2013 AISI 904L comparison<\/a>.<\/p>\n
