ASTM A312 316L Stainless Steel Pipe
1. Standard: ASTM A312 / ASME SA312
2. Size: 1/2”- 48”
3. Thickness: SCH5~SCHXXS
4. Length: Single Random Length, Double Random Length and Customized
ASTM A312 316L stainless steel pipe is derived from the classic "18-8" stainless steel with molybdenum added to enhance pitting resistance in chloride environments. S31603 is a low-carbon version of TP316, and the low carbon content makes it more resistant to sensitization, thereby improving weld corrosion resistance. Suitable for marine environments, chemical processing and pharmaceutical industries. Stainless steel pipe 316L SCH40 is suitable for medium-range pressure vessels, while SCH10S has relatively thin wall thickness.
