Stainless steel

Stainless steel resists corrosion because of its chromium content. It is priced by grade first - a 304 sheet and a 202 sheet that look the same can differ greatly in price - then by form, thickness and finish. Float your exact grade and let verified sellers quote.

Common grades

GradeFamilyWhere it is used
304 / 304LAustenitic (chromium-nickel)Food, dairy, pharma, kitchen, general fabrication
316 / 316LAustenitic with molybdenumChemical, marine, coastal, pharma
202 / 201Austenitic, low nickel (chromium-manganese)Utensils, decorative, railings in dry areas
409FerriticExhaust systems, containers
430FerriticAppliances, kitchen equipment, interiors
Duplex (2205 etc.)Austenitic-ferriticHigh strength plus corrosion resistance

Forms and finishes

Stainless is sold as cold rolled and hot rolled coils and sheets, plates, pipes and tubes (welded or seamless), round and flat bars, and angles. Sheet finishes include 2B (smooth mill finish), BA (bright annealed), No. 4 / hairline (brushed) and No. 1 (hot rolled, annealed and pickled). State the finish - it changes the price.

What to put in a stainless inquiry

  1. Grade (304, 316L ...) and standard (IS 6911, ASTM A240 ...).
  2. Form and size: thickness x width x length, OD x wall, or bar diameter.
  3. Finish, and PVC film if needed.
  4. Mill test certificate with chemical analysis.
  5. Quantity, delivery site and payment terms.

Check the grade on delivery

Grade mix-ups (for example 202 supplied as 304) are the most common stainless dispute. Match the heat number on the material to the test certificate, and for large orders consider a quick spectro or XRF check of the nickel content.

How buying works on the portal

On Indian Steel Portal you float one inquiry for stainless steel - grade, sizes, quantity, preferred makes, delivery city and payment terms. KYC-verified mills, stockists and traders quote against it in a live reverse auction with a minimum decrement and a soft-close, ranked L1 to L4 on landed cost. You award L1 or any ranked bidder, and the deal note - with GST, MTC and weighment terms - is generated for both sides.

Frequently asked questions

What is the difference between SS 304 and 316?

316 contains molybdenum, which improves resistance to chlorides - sea air, salt and many chemicals. 304 is the general-purpose grade and costs less.

Is 202 stainless steel the same as 304?

No. 202 replaces much of the nickel with manganese, so it is cheaper but less corrosion-resistant. It suits dry indoor uses, not food plants or coastal sites.

What is the HSN code for stainless steel sheets?

Flat-rolled stainless steel is under HSN 7219 (600 mm or wider) and 7220 (narrower); bars and angles under 7222. GST is 18%.

What does 2B finish mean?

2B is a smooth, slightly reflective cold-rolled mill finish - the most common sheet finish.

How do I check that I received the right grade?

Match heat numbers to the mill test certificate and, for large lots, test nickel and molybdenum content with a portable analyser.
