Stainless Steel 316L Pipe Price

316L stainless steel pipe pricing depends on size, schedule, wall thickness, form (seamless vs welded), quantity, and raw material costs. Indian market pricing starts from approximately INR 430/kg for standard welded sizes. Common welded sizes range from $3 to $15 per foot (NPS 1/2" to 4", Sch 10S to 40). Larger diameters and seamless pipe cost more. Request a quote for the current 316L stainless steel pipe pricing. Volume discounts apply for bulk orders.

Chemical Composition of Stainless Steel 316L Pipe

The chemical composition of SS 316L pipe, along with its elemental composition, is listed in the table given below:

Element Composition Scale Specification
Carbon C
Max 0.030%
Manganese Mn
Max 2.00%
Phosphorus P
Max 0.045%
Sulfur S
Max 0.030%
Silicon Si
Max 1.00%
Chromium Cr
16.0 - 18.0%
Nickel Ni
10.0 - 14.0%
Molybdenum Mo
2.00 - 3.00%
Nitrogen N
Max 0.10%

The low carbon limit (0.030% max) defines the "L" in 316L. It reduces intergranular corrosion risk in welded joints, a critical factor for piping in aggressive chemical or marine service.

Mechanical Properties of 316L Stainless Steel Pipe

SS 316L pipe handles pressure-bearing applications reliably at these values. The 35% elongation means the material absorbs deformation without cracking under thermal cycling.

Frequently Asked Questions:

What is the difference between 316 and 316L stainless steel pipe? +
316L pipe has a carbon limit of 0.030% max, while 316 allows up to 0.08%. Lower carbon prevents carbide precipitation during welding, making 316L the preferred grade for welded pipe in corrosive service.
What is the Cost of SS 316L pipe? +
Pricing varies by size, schedule, form, and quantity. Common welded sizes range from ₹280 to ₹595 per kg in India and $3 to $15 per foot internationally. Contact Sachiya Steel International for a current quote.
What is the Material of 316L Pipe? +
316L pipe is an austenitic stainless steel with 16.0 to 18.0% chromium, 10.0 to 14.0% nickel, and 2.00 to 3.00% molybdenum. UNS designation is S31603; the European equivalent is W.Nr 1.4404.
What Sizes are Available for 316L Stainless Steel Pipe? +
Sizes range from 1/8" to 24" NPS in schedules 5S, 10S, 40, 80, and 160. Standard length is about 20 feet, and we can cut to custom lengths.
What is the Pressure Rating of 316L Stainless Steel Pipe? +
The pressure rating depends on the pipe size (NPS) and wall thickness (schedule), as defined by ASME B31.3. Base mechanical properties are 485 MPa tensile and 170 MPa yield per ASTM A312. Higher schedule numbers mean thicker walls and higher working pressures.
What ASTM Standard covers 316L Stainless Steel Pipe? +
ASTM A312 / ASME SA-312 covers seamless and welded austenitic stainless steel pipe. ASTM A358 applies to electric-fusion-welded pipe. ASTM A778 covers welded, unannealed tubular products.
Is 316L Pipe Suitable for Seawater and Marine Applications? +
The 2.00 to 3.00% molybdenum in 316L pipe helps it resist pitting and crevice corrosion in chloride-rich environments. Because of this, it is commonly used on offshore platforms, on ships, and in desalination plants.
Where can I buy 316L Stainless Steel Pipe? +
Sachiya Steel International stocks 316L stainless steel pipe in seamless and welded forms, sizes 1/8" to 24" NPS. We export globally with seaworthy packaging and full MTC 3.1 documentation. Contact us for availability.
