What does ASTM A312 TP 316L represent?

The A312 type TP316L belongs to a low-carbon austenitic grade of stainless steel. The A312 TP316L is produced with a superior composition of nickel, chromium, and molybdenum, allowing them to be used across different industries. This gives the items in this grade superior corrosion and oxidation resistance properties.

 

What is the difference between TP316 and TP316L?

The key difference between 316 and 316L stainless steel is the carbon content. While 316 has a maximum carbon content of 0.08%, 316L has a maximum carbon content of only 0.03%.

 

What is the difference between ASTM A312 and 316?

The 316L stainless steel pipe has a lower carbon content than the ASTM A312 TP316 which means, there is less intergranular precipitation and local corrosion due to welding. Also, the material has molybdenum in addition to chromium and nickel which is specifically resistant to chloride ion stress corrosion.
