Source SS 316 Flange from India
India Supply Solutions sources SS 316 Flange from qualified Indian manufacturers against the buyer's exact grade, standard, dimensions, quantity and inspection plan. We are the procurement partner — not the mill or manufacturer. Ready-stock sourcing is checked through our Indian stockist and manufacturer network; exact make, heat / MTC, dimensions, quantity and dispatch status are confirmed per RFQ.

Build a supplier-comparable enquiry by defining type, nominal size, pressure class, facing, drilling standard, dimensions, heat treatment and marking, material designation, governing standard and edition, quantity, destination, acceptance criteria and required certification.
RFQ definition: type, nominal size, pressure class, facing, drilling standard, dimensions, heat treatment and marking.
Typical family applications: process equipment, food and beverage, chemical service, heat-resistant service, fabrication and general corrosion-resistant engineering. Suitability remains the buyer's engineering decision.
SS 316 Flange sizes and dimensions to specify
Useful enquiry selectors—not an inventory or universal availability claim. Exact manufacturability is confirmed against grade, standard, route, tolerance and quantity.
Common systems include ASME B16.5, ASME B16.47 or an EN / DIN / JIS dimensional standard; the governing edition must be stated.
Range guide: Common RFQ guide: NPS 1/2 to 24 under B16.5 and NPS 26 to 60 under B16.47, where the selected material and manufacturer are capable.
| Type | Weld neck / slip-on / blind / socket weld / threaded / lap joint |
|---|---|
| Facing | RF / FF / RTJ or buyer-specified facing finish |
| Drilling | ASME class or EN PN system; never infer one from nominal size alone |

How we compare SS 316 Flange manufacturers
Grade designation, heat traceability and required certification are matched to the RFQ.
Route, size range, tolerances, heat treatment and form-specific capability are checked.
Dimensional, visual, PMI / chemistry, mechanical or NDT controls are defined where applicable.
MTC, inspection records, packing and export documents are aligned before dispatch.
No material grade, route, standard or dimension substitution without written buyer approval.
Supplier offers are compared on the same technical basis before commercial selection.
SS 316 Flange sourcing questions
How do I source SS 316 Flange from India?
Send the exact material designation, product standard, type, nominal size, pressure class, facing, drilling standard, dimensions, heat treatment and marking, quantity, destination and required inspection. India Supply Solutions then identifies and compares suitable Indian manufacturers or suppliers.
How do I compare the qualified SS 316 Flange manufacturers in India?
Compare actual capability for the named grade and form, applicable standard, traceability, test documentation, delivery record, inspection readiness and commercial transparency—not only the lowest quoted price.
Can you quote SS 316 Flange price in India?
Yes, after grade, standard, dimensions, quantity, packing and delivery basis are defined. We do not publish a fabricated fixed price for specification-sensitive metal products.
What documents should be requested for SS 316 Flange?
Depending on the requirement, buyers may request MTC / heat traceability, inspection records, PMI or chemistry verification, mechanical tests, NDT and packing / export documents.

SS316 flange procurement: a clearer technical and commercial basis
“SS316 flange” is a useful search term, but a purchase order needs more detail. For a forged flange enquiry, specify ASTM A182 F316 or the exact alternative material specification approved by your engineering team. AISI 316 and UNS S31600 identify material terminology; they do not define flange dimensions or prove that a finished item meets the ordered forging specification.
SS316 versus SS316L
316L is the lower-carbon variant commonly considered for welded service. Select F316L / SS316L when the project specification requires it. A supplier offering 316/316L dual certification must demonstrate compliance with both ordered grade requirements in the material records. Do not accept a handwritten grade change or a generic stock description as dual-certification evidence.
Size, class and facing enquiries
ASME B16.5 covers NPS 1/2 through 24 for Classes 150, 300, 400, 600, 900 and 1500. Its Class 2500 range stops at NPS 12. Type-specific tables and restrictions still apply. For large-diameter work, specify ASME B16.47 and Series A or B explicitly. A size range is a standard scope, not an ISS stock list.
EN 1092-1 PN flanges, IS 6392 steel pipe flanges and JIS B2220 enquiries require their own dimensional basis. Do not convert a Class designation to PN or assume matching bolt holes from DN/NPS alone. Pressure capability depends on the material and design temperature as well as the rating designation.
Useful size enquiries include NPS 3/4, 1 1/4, 1 1/2, 2 1/2, 3, 5, 10, 14, 18 and 20 as well as the common sizes above. Submit a line list rather than assuming every type, class and size is available. Bore or pipe schedule matters for weld-neck matching. A blind flange has no through-bore connection.
Example RFQ line
Illustrative enquiry: forged weld-neck flange, ASTM A182 F316 to the specified edition, ASME B16.5, NPS 2, Class 150, RF, matching pipe schedule and weld-end detail to be stated, 20 pieces, required MTC and inspection scope, destination and delivery basis to be confirmed. This is an enquiry example, not a live offer.
Manufacturer and stockist selection
Check who manufactured the flange, who holds the stock and who issues each document. Review the supplier's capability for the actual forging, machining and heat-treatment route. For stock material, request lot-specific dimensions, marking and heat-to-MTC records. For a new production order, agree inspection hold points and lead time before placement. Public catalogue evidence is a starting point for qualification, not proof of an ISS partnership.
For a useful price comparison, ask each supplier to quote the same grade, flange type, standard edition, rating, bore, face finish, certificate and inspection scope. Separate product price from testing, packing, inspection and agreed delivery costs. Stock availability, heat identity, quantity and dispatch timing must be confirmed against the actual lot before order acceptance. ISS coordinates sourcing, supplier verification, inspection and export requirements; it is not the flange manufacturer.
Information to include with your enquiry
- Material: named forging specification, grade and edition. Include the required heat treatment and certificate type.
- Dimensions: governing flange standard, NPS or DN, pressure class or PN, type, facing and drilling. A nominal diameter alone does not define a flange.
- Connection: matching pipe outside diameter and bore or schedule, weld-end preparation where applicable, and the mating flange and gasket requirements.
- Inspection: dimensional and visual checks, heat-to-certificate traceability, marking, face finish and any agreed PMI, mechanical, corrosion or NDT requirements.
- Commercial basis: quantity per line, approved make restrictions, destination, delivery date, packing and Incoterm with named place.
