SUS316L Austenitic Stainless Steel
Ultra-low carbon austenitic stainless steel

 

Characteristics of SUS316L:
SUS316L is a kind of ultra-low carbon austenitic stainless steel. It is developed by improving the intergranular corrosion resistance on the basis of SUS316. Compared with the conventional chromium-nickel austenitic stainless steels, such as SUS304, SUS316 has much better general corrosion resistance, pitting corrosion resistance as well as crevice corrosion resistance. SUS316L enjoys the features of relatively high ductility, stress corrosion resistance, compressive strength and high temperature performance. SUS316L is quite suitable for the applications of SUS316 where the products specially required intergranular corrosion resistance. What's more, SUS316L is equipped with the typical characteristics of austenitic stainless steel, i.e. good workability and formability, high weldability and excellent corrosion resistance. It is suitable for multi-layer welding, and there is no edge corrosion tendency. It has excellent corrosion resistance to sulfurous acid, sulfuric acid, phosphoric acid, acetic acid, formic acid, chlorine salt, halo, sulfite, etc.

Pitting corrosion resistance of SUS316L:
The pitting resistance equivalent number (PREN) of SUS316L is 25.2 while the PREN of SUS304 is just 19.0. That is to say, the pitting resistance of SUS316L is better than that of SUS304.

 

Solution treatment of SUS316L:
The temperature of solution treatment is 1010~1150℃. Cool rapidly.

 

Applications of SUS316L:
SUS316L is mainly suitable for the applications of SUS316 where the products specially required intergranular corrosion resistance. SUS316L is also available for fabricating synthetic fiber, petroleum, chemical, textile, fertilizer as well as the industrial equipment of printing and dyeing, such as towers, tanks, containers, pipes and so on.
