What is Stainless Steel 316 Pipe?
Stainless Steel 316 (often designated as UNS S31600 or WNR 1.4401) is an austenitic chromium-nickel stainless steel containing molybdenum. This addition of molybdenum significantly enhances its corrosion resistance compared to Grade 304, particularly improving resistance to pitting and crevice corrosion in chloride environments. This characteristic earns it the common name "marine grade stainless steel" and makes 316 stainless pipe a top choice for such applications.
Key Characteristics of SS 316 pipe:
- Superior Corrosion Resistance: Excellent performance against general corrosion, pitting, and crevice corrosion, especially in chloride-rich and acidic environments – ideal for stainless steel 316 pipes.
- Good Strength: Offers reliable mechanical properties, including a typical minimum tensile strength of 515 MPa and yield strength of 205 MPa.
- High Temperature Performance: Maintains integrity at elevated temperatures, suitable for applications like heat exchangers (Melting point approx. 1400°C / 2500°F).
- Weldability & Formability: Can be readily welded and formed using standard fabrication practices.
- Durability: Long service life even in harsh conditions.
Understanding Stainless Steel 316 Pipe & Tube Types
Amardeep Steel Centre supplies stainless steel 316 pipes and tubes in various forms to suit diverse applications:
- Stainless Steel 316 Seamless Pipe / Tube: Made from a solid billet. No welds, no seams at all. This process results in excellent pressure ratings and uniform strength, making this type of 316 ss pipe ideal for critical high-pressure applications. Typically available in ODs from 1/2" to 16". The 316 ss tube variant offers the same seamless benefits.
- Stainless Steel 316 Welded Pipe / Tube (including ERW & EFW): Formed by rolling strip or plate and welding the seam.
- ASTM A312 TP316 Welded Pipe: A common specification for welded 316 stainless pipe suitable for high-temperature and general corrosive service.
- ERW (Electric Resistance Welded) Pipe: Produced by passing an electric current through the edges to fuse them. Versatile and durable, available in a wide range of sizes.
- EFW (Electric Fusion Welded) Pipe: Often used for larger diameters (e.g., ASTM A358), allowing filler metal during welding.

Frequently Asked Questions
What is 316 stainless steel pipe?
Stainless Steel 316 Pipe is an austenitic stainless steel grade pipe that has good resistance to chloride ion corrosion stress cracking. For this reason, the pipe is used in marine and sea water applications with ease.
What is the difference between 304 and 316 stainless steel piping?
The key difference between 304 and 316 stainless steel that makes them different is the addition of molybdenum, an alloy that drastically enhances corrosion resistance, especially for more saline or chloride-exposed environments. 316 stainless steel contains molybdenum, but 304 does not.
What makes Stainless Steel 316 Pipe different from other grades like 304?
The key difference is the addition of molybdenum (typically 2-3%) to 316 Stainless Steel Pipe. This significantly enhances its corrosion resistance, particularly against pitting and crevice corrosion in chloride environments (like saltwater or coastal areas). This makes SS 316 pipe the preferred choice for marine applications and many chemical processing tasks where 304 might not suffice.
Which is better, 316 or 304 stainless steel?
If you don't need the added resistance of 316, standard 304 grades will offer similar performance and longevity at a lower price point. However, in situations where the added resistance is needed, 316 often improves the functional lifespan of the steel products by years.
Is 316 Stainless Steel Pipe magnetic?
In its annealed (softened) state, 316 Stainless Steel Pipe is essentially non-magnetic due to its austenitic structure. However, significant cold working (like bending or heavy forming) can induce slight magnetism.
How can I get a price for 316 Stainless Steel Pipe from Amardeep Steel Centre?
Pricing for ss 316 pipe depends on market conditions, grade (316/316L), type (seamless/welded), dimensions, quantity, and any required processing. The best way to get an accurate quote is to contact our sales team directly via phone, email, or our website's quote request form.
