316L Stainless Steel Pipe is a low-carbon austenitic stainless steel pipe that offers excellent corrosion resistance, superior weldability, and high durability. The addition of molybdenum improves resistance to pitting and crevice corrosion, making it ideal for marine, chemical, pharmaceutical, and food processing applications.
ASTM A312 TP316L is the standard specification for seamless, welded, and heavily cold-worked austenitic stainless steel pipes intended for high-temperature, corrosive, and pressure-service applications. It is one of the most widely used specifications for industrial stainless steel piping.
The primary difference is carbon content. 316L contains a maximum of 0.03% carbon, while 316 contains up to 0.08%. The lower carbon content of 316L minimizes carbide precipitation during welding, providing better resistance to intergranular corrosion and making it the preferred choice for welded piping systems.
