Everything you Need to About 316 / 321 Stainless Steel Tube and Pipe

Alloy 316 is considered as austenitic stainless steel which comes under molybdenum-bearing grade. And 321 stainless steel is of chromium-nickel steel. Both are known for its excellent corrosion resistance properties, formability, weldability and strongest machinability.  321 stainless steel tubes are widely used in aircraft collector rings, high-temperature chemical process equipment etc. Whereas 321 stainless steel is most commonly used in Condensers, evaporators, pollution control equipment, and especially in chloride environments.

Those stainless pipes are considered as the best 321 Stainless Steel Tube which has the ability to resistant to sterilizing solutions, atmospheric corrosion, and inorganic.  In Today’s market, many stainless steel suppliers provide 316 Stainless Steel Tube Fittings better. But, some of the main characteristics of these alloy should not be avoided.

Austenitic stainless steel alloy 316/316L
Austenitic stainless steel alloy 316/ 316L is a kind of molybdenum-bearing material. In comparison to the austenitic stainless steel alloy 304, this unique type of alloy has a rich content of nickel and molybdenum in these pipes, thereby developing a strong corrosive resistant property in the material, in a manner to reduce the risk of rust in the material.

The resistance property in these pipes helps in factors regarding pitting and crevice corrosion in chloride environments.

Why should you opt for 316/316L stainless steel?
These types of pipes and tubes illustrate exceptional high-temperature material, creep and stress-rupture, stability. On the other hand, it also has impressive formability and weldability.

What is the difference between 316 and 316L stainless steel?
Unlike 316, 316L stainless steel pipes because of its less carbon content, are protected from sensitization. Meanwhile, 316L is commonly used in heavy gauge welded components because of their higher grades on the cons list than on pros.

What would 321 stainless steel be like?
Stainless steel 321 is a type of chromium-nickel material, which was developed with an enhanced property of intergranular corrosion resistivity.  This type of material’s resistance can obstruct atmospheric corrosion, sterilizing solutions, and various inorganic as well as organic compounds.

Keeping 321 stainless steel in the account, they are much beneficial in making aircraft collector rings, exhaust manifolds, and are also used in equipment for processes with the use of high-temperature chemicals.

What is special about 321 stainless steel- in the version of 304?
This type of material consists of a Titanium-stabilised version of 304. These are used only under a specific condition that is within the sensitizing temperature range.

Speaking of resistance, this type of material of stainless steel hinders the concept of sensitization.

At high temperatures, they are coupled with their higher strengths, thereby making it easy to handle in any type of application, unlike other alloys like 304 or 304L.
