Stocking 316 Stainless Steel Pipe, 316 SS Pipe, 316 SS Tube, Stainless Steel 316 Seamless Tube and ASTM A312 TP316 Welded Pipe in India
At Amardeep Steel Centre, SS 316 Pipe and Tube is available across every major construction type in seamless, ERW, EFW, and LSAW from 1/8" NB to 30" NB in schedules SCH 5S through XXS, compliant with ASTM A312 / ASME SA312 (TP316) and ASTM A358 / ASME SA358. Whether your purchase order specifies it as 316 Stainless Steel Pipe, SS 316 Pipe, Stainless 316 Pipe, or Stainless Steel Pipe 316, the material, specification, and test certification are identical across all descriptions.
Beyond standard pipe sizes, we stock 316 stainless steel tubing in precision and instrumentation sizes to ASTM A269 / A213 suited for applications that require tighter OD and wall-thickness tolerances than nominal pipe schedules allow. All material ships with EN 10204 3.1 / 3.2 Mill Test Certificates and IBR Form III-D as standard; third-party inspection by SGS, Bureau Veritas, or TÜV is available on request.
What Is Stainless Steel 316 Pipe?
Stainless Steel 316 Pipe is an austenitic, molybdenum-bearing stainless steel pipe manufactured to ASTM A312 / ASME SA312 TP316, distinguished from standard austenitic grades by the deliberate addition of 2–3% molybdenum. Molybdenum raises the alloy's resistance to electrochemical attack specifically pitting and crevice corrosion initiated by chloride ions which is why 316 is the standard specification for marine piping, offshore platforms, chemical process lines, pharmaceutical fluid systems, and food/beverage installations where Grade 304 provides insufficient protection.
The same alloy is sold and specified internationally under several equivalent designations: UNS S31600, DIN/WERKSTOFF 1.4401, JIS SUS 316, and Euronorm X5CrNiMo17-12-2 — all describing identical chemistry and the same underlying ASTM A312 TP316 pipe product.

SS 316 vs SS 304 vs 316L vs 316H vs 316Ti — Which Grade Do You Need?
| Grade | Key Difference | Best For |
| SS 316 | Standard molybdenum-bearing austenitic grade | General marine, chemical, pharma piping |
| SS 304 | No molybdenum, lower chloride resistance, lower cost | Non-marine, general industrial use |
| SS 316L | Low-carbon version (≤0.03% C), better weldability, no carbide precipitation | Welded assemblies, sanitary/pharma |
| SS 316H | Higher carbon (0.04–0.10%), better high-temp creep strength | High-temperature service >500°C |
| SS 316Ti | Titanium-stabilized, resists carbide precipitation at high temp | High-temp welded applications |
For a side-by-side comparison, see our guide: 304 vs 316 Stainless Steel – What's the Difference →
For welded fabrications, SS 316L (UNS S31603) is preferred over 316: the lower carbon content (≤0.03% vs ≤0.08%) eliminates carbide precipitation (sensitisation) in the heat-affected zone, preserving intergranular corrosion resistance without requiring post-weld annealing.

Manufacturing Process of SS 316 Pipes
- Seamless (ASTM A312 / ASME SA312): Produced via hot extrusion or rotary piercing from solid billet, followed by cold drawing and solution annealing at 1,010–1,120°C. No seam weld — uniform wall thickness suitable for high-pressure and high-cycle fatigue service. View Seamless Pipes & Tubes
- ERW (ASTM A312 / ASME SA312): Strip formed into a tube and seam-welded by electric resistance. Weld seam is heat-treated to achieve corrosion resistance equivalent to parent metal. Standard for general process piping and HVAC at lower cost than seamless. View Welded Pipes & Tubes
- EFW (ASTM A358 / ASME SA358): Electric fusion welded from plate/strip, standard for large-diameter (6"–100" OD) fabricated pipe in chemical and desalination plant applications.
- LSAW: Longitudinally submerged arc welded; used for heavy-wall structural and high-pressure large-diameter applications where EFW is insufficient.
Surface Finish Options for Stainless Steel 316 Pipes
We supply Stainless Steel 316 Pipes with the following finishes:
- Bright Annealed (BA): Ra ≤0.5 µm reflective finish, ideal for pharmaceutical, food, and semiconductor hygienic piping.
- Annealed & Pickled (AP): Standard oxide-free surface for industrial, marine, and offshore applications.
- Polished/Mirror: Ra ≤0.25 µm, for architectural and decorative structural applications.
- Passivated: Post-fabrication passivation per ASTM A380 to restore oxide layer after welding or machining.

Corrosion Resistance — PREN & Critical Pitting Temperature
SS 316 has a Pitting Resistance Equivalent Number (PREN) of approximately 24–26, calculated as %Cr + 3.3×%Mo + 16×%N. This exceeds Grade 304’s PREN of ~18–20, confirming superior chloride resistance. Critical Pitting Temperature (CPT) for 316 in 1M NaCl typically exceeds 15°C versus below 0°C for 304.

Frequently Asked Questions - Stainless Steel 316 Pipes & Tubes
What is Stainless Steel 316 Pipe?
SS 316 pipe is an austenitic, molybdenum-bearing stainless steel pipe (ASTM A312/ASME SA312 TP316, UNS S31600, DIN 1.4401) known for excellent corrosion resistance, especially in chloride/marine environments.
What is the difference between 304 and 316 stainless steel pipe?
316 contains 2–3% molybdenum, which 304 lacks, giving 316 significantly better resistance to chlorides, seawater, and acidic chemicals.
What is the difference between SS 316 and SS 316L pipe?
316L is the low-carbon version of 316 (≤0.03% carbon), which prevents carbide precipitation during welding making it preferred for welded sanitary and pharmaceutical applications.
What is the price of SS 316 pipe per kg?
Indicative prices range from Rs. 260–Rs. 360 per kg depending on size, schedule, and whether the pipe is seamless or welded.
Is 316 stainless steel pipe magnetic?
In the annealed condition, 316 is largely non-magnetic (austenitic structure), though slight magnetism can occur after cold working.
Is SS 316 pipe suitable for marine and seawater applications?
Yes — 316 is often called 'marine grade' stainless steel due to its molybdenum content, which resists pitting and crevice corrosion from chlorides in seawater.
What is the maximum service temperature for SS 316 pipe?
316 performs well up to approximately 870°C intermittently (oxidation resistance limit). For continuous service, ASME B31.3 allowable stress limits apply from the applicable table; 870°C is an intermittent oxidation limit only. For sustained high-temperature service, 316H or 316Ti is recommended.
What schedules are available for 316 stainless steel pipe?
Standard schedules include SCH 5S, 10S, 40S, 80S, and 160, plus XS and XXS for heavy-wall applications.
What is the difference between seamless and welded (ERW) 316 pipe?
Seamless pipe is made without a weld seam (extrusion/rotary piercing), offering uniform strength for high-pressure use; ERW/welded pipe is formed and seam-welded, suitable for general industrial applications at a lower cost.
How can I get a price quote or test certificate for SS 316 pipe from Amardeep Steel Centre?
Submit your size, schedule, and quantity via our enquiry form or contact us directly — we provide pricing along with sample MTC/EN 10204 3.1 documentation.
What is 316 stainless steel tubing used for?
316 stainless steel tubing (ASTM A269/A213) is used for instrumentation lines, hydraulic systems, heat exchangers, and precision sanitary applications where tight OD/wall-thickness tolerances are required — unlike pipe, which is sized by nominal bore (NB) and schedule.
What sizes are available for 316 SS tube?
316 SS tube is available from 1/16" OD up to 2 1/2" OD in wall thicknesses from 0.010" to 0.250", in seamless and welded forms.
