ASTM A312 TP316L Stainless Steel Tube For Pressure Parts in Power Boilers
Specifications
ASTM A312 TP316L Stainless Steel Tube refers to S31603 UNS destination 1.4404, it has better corrosion resistance than TP316 because of the lower Carbon content. 316L maximum carbon content of 0.03% which 316 maximum of 0.08%, higher carbon will increase intergranular corrosion. Therefore, 316L is suitable for applications where carbon precipitation needs to be avoided. This stainless steel is widely used for welding the components, its special carbon content combined with welding ensures maximum resistance to general corrosion, especially applicable for heavy-duty components
316L is considered more resistant to oxidation than Type 316, especially in warm marine environments. Again, its low carbon content protects it from carbon precipitation. The metal also exhibits resistance at extremely low temperatures, even down to cryogenic levels. In terms of heat resistance, 316L exhibits better creep resistance, fracture stress resistance, and overall strength than other stainless steel grades.

ASTM A312 TP316L Stainless Steel Tube Application
Key Distinction from TP316/TP316H:
While all three grades (316, 316L, 316H) offer good corrosion resistance, TP316L is specifically chosen for its enhanced corrosion resistance in welded structures and in environments prone to intergranular attack. It is not designed for high-temperature strength like TP316H.
