321 316L Metal Stainless Steel Pipe BA 4k 8k Finished Brigth Surface Ss Tube
What is the difference between 321 and 316 stainless steel?
The most popular acid-resistant material is steel AISI 316, which
exhibits increased resistance to corrosion
in very aggressive chemical environments. The third tested type is AISI 321, which shows high resistance
to inter-crystalline corrosion and resistance to the work in higher temperatures, i.e. 400 – 800°C [9].
What does 316L mean in stainless steel?
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 the surface finish of stainless steel?
Considered the most widely used surface finish, 2B is the basis for
most polished and brushed finishes. Such
common stainless steel grades as 201, 304, 304L and 316L come in a standard 2B finish.
