SS 316L pipe is a low carbon variant of SS 316. SS 316L contains a lower carbon content (0.03% max) and does not form chromium carbides after welding, which has enhanced weldability and better resistance to intergranular corrosion. Alloy 316L does not require heat treatment after welding and is suitable for more severe welding applications. It is widely used in pipe and fitting applications in welding environments.
ASME SA312 TP316L Seamless Pipe Applications:
- Pipes and fittings in welding environments
- Chemical processing equipment
- Nuclear industry
- Medical equipment
- Food and beverage industry
- Water treatment
