317L stainless steel seamless pipe is a low-carbon, molybdenum-bearing austenitic stainless steel that offers superior corrosion resistance compared to 316L, especially in acidic and chloride-rich environments. The seamless manufacturing process ensures a smooth internal surface, making it ideal for high-pressure and high-temperature applications.

✅ Enhanced Corrosion Resistance:

• Higher molybdenum (3-4%) content provides excellent resistance to pitting, crevice corrosion, and general corrosion, especially in harsh environments.
• Performs better than 316L in acidic conditions (e.g., sulfuric, phosphoric, and acetic acids).

✅ High Strength & Durability:

• Superior mechanical properties at elevated temperatures.
• Withstands high pressure and stress.

✅ Low Carbon Content (L-Grade):

• Reduces carbide precipitation, preventing intergranular corrosion after welding.

✅ Smooth Internal Surface:

• Ideal for applications requiring hygienic and smooth flow (e.g., pharmaceuticals, food processing).

• Chromium (Cr): 18-20%
• Nickel (Ni): 11-15%
• Molybdenum (Mo): 3-4%
• Carbon (C): ≤ 0.03% (low carbon for better weldability)
• Manganese (Mn): ≤ 2%
• Silicon (Si): ≤ 1%

🏭 Chemical & Petrochemical Processing: Ideal for handling corrosive chemicals.

• Outside Diameter (OD): 19.05 mm (this is exactly ¾″ in imperial terms)

• Material: Stainless Steel (commonly grades like 304 / 304L / 316 / 316L depending on application)

Steel gauge isn’t an exact metric measurement, but commonly accepted approximate thickness values are:

So your pipes will be roughly:

• 19.05 × 1.90 mm (14 g)

• 19.05 × 1.60 mm (16 g)

• 19.05 × 1.20 mm (18 g)

• 19.05 × 0.90 mm (20 g)

Note: These gauge-to-mm conversions are standard approximations. Exact thickness can vary slightly with manufacturer and steel type.

These diameter/thickness ranges are commonly used for:

✅ Structural tubing
✅ Furniture frames
✅ Handrails
✅ Automotive parts
✅ Light industrial fabrication
✅ Food / beverage equipment (if grade 304/316)
