SS pipe 202 is an austenitic stainless steel pipe made from chromium, nickel and manganese. It costs less than 304 because manganese replaces part of the nickel. It offers good strength, a clean finish and fair corrosion resistance, which makes it a smart pick for furniture, railings, fabrication and general structural work.
If you build, fabricate or trade in Delhi NCR, this grade matters. Contractors in Sonipat, Kundli, Panipat, Gurugram and Faridabad use 202 pipe for gates, staircase railings, shop fittings, kitchen fixtures and light structural frames. The right choice saves money. The wrong one rusts early. This guide shows you the difference.
SS 202 belongs to the 200-series of stainless steels. These alloys use manganese and nitrogen to do part of the job that nickel does in the 300-series. Nickel is expensive. Manganese is not. That is why 202 pipe sits at a lower price point than 304.
Typical composition for 202 stainless steel, according to a published manufacturer datasheet:
Chromium forms a thin protective layer on the surface. That layer is what makes steel “stainless.” Manganese adds hardness and strength.
202 vs 304: The Honest Comparison
Buyers ask this first, so here is a straight answer.
| Feature | SS 202 | SS 304 |
|---|---|---|
| Chromium | 17-19% | 18-20% |
| Nickel | 4-6% | 8-10.5% |
| Manganese | 7.5-10% | max 2% |
| Corrosion resistance | Good in dry and mild settings | Higher, handles harsher settings |
| Price | Lower | Higher |
| Best for | Furniture, railings, fabrication, indoor and sheltered use | Food processing, coastal, chemical and hygiene-critical use |
The rule of thumb: use 202 where budget matters and exposure is mild. Use 304 where salt, acids, constant moisture or strict hygiene are involved. Source for composition: Indian Stainless Steel Development Association (ISSDA)].
Strength and durability
Manganese raises hardness and tensile strength. The pipe holds its shape under load, which suits structural frames and supports.
Weldability and formability
202 pipe welds and bends well. Fabricators can cut, shape and join it without special tools. That saves labour time on site.
Surface finish
The pipe takes a bright polish. It looks good in visible applications such as handrails, balustrades and decorative frames.
Cost efficiency
Lower nickel content means lower material cost. For large orders, the saving adds up fast.
Pipes come in different shapes for different jobs. Round pipes suit railings and fluid or structural use. Square and rectangle pipes give flat surfaces and load-bearing strength for frames. Oval pipes add a design touch to railings and decorative work.

No stainless steel is fully rust-proof. SS 202 resists rust well in dry and mild conditions, but it can stain in salty, acidic or constantly wet environments. For those, choose 304.
SS 304 has more nickel and chromium, so it resists corrosion better. SS 202 has more manganese and less nickel, which makes it cheaper and strong enough for most general uses.
Yes. 202 pipe is widely used for railings, gates and grills because it looks bright, welds easily and costs less. Use 304 if the railing sits near the coast or a pool.
It is not the first choice for food-grade or potable use. 304 and 316 are preferred where strict hygiene and corrosion rules apply. Check local standards before you decide.
Ask for a mill test certificate and buy from a manufacturer. A reliable supplier shares the chemical composition and test records for each batch.
