316N Stainless Steel Round Pipe

Grade: 316N/S31651

Size:

Seamless: 6mm*1mm-720mm*50mm

Welded: 12mm*0.5mm-2000mm*100mm

Coiled: 4mm*0.3mm-32mm*3mm

Standard: ASTM A312, ASTM A213 etc.

Surface: No.1(Pickling), Bright(Polished)

316N Stainless Steel Pipe is a nitrogen-strengthened version of 316 stainless steel, combining molybdenum-enhanced corrosion resistance with increased strength. Nitrogen provides solid-solution strengthening while preserving the austenitic structure and good corrosion performance. The grade is suitable for pressure-bearing components, chemical processing, marine systems, heat exchangers, and other applications requiring higher strength without sacrificing the corrosion resistance associated with 316 stainless steel.
