What Is the Difference Between 201 and 202 Stainless Steel Pipes?
When customers compare stainless steel materials for construction, decoration, or industrial projects, a common question arises: what is the difference between 201 and 202 stainless steel pipes? While both belong to the 200-series austenitic stainless steels and look similar at first glance, they differ in composition, performance, and cost-effectiveness. At Ganyeah Group, we help global clients choose the most suitable grade to balance durability, efficiency, and budget.

Chemical Composition Differences
The first difference between 201 and 202 stainless steel pipes lies in chemical composition:
- 201 stainless steel uses manganese and nitrogen to partially replace nickel, making it more affordable while retaining an austenitic structure.
- 202 stainless steel (ASTM designation, equivalent to 1Cr18Mn8Ni5N in China) has slightly higher chromium and manganese content, which provides greater strength and somewhat improved corrosion resistance.
Property and Performance Comparison
Another key difference between 201 and 202 stainless steel pipes is in mechanical and corrosion properties:
- 201 stainless steel pipe offers good polishing quality, high density, and moderate resistance to acid and alkali. It is ideal for decorative and light-duty industrial uses.
- 202 stainless steel pipe has higher room-temperature strength, retains oxidation resistance up to 800°C, and provides better performance in higher-temperature environments.
In practical terms, 202 is slightly stronger and more corrosion-resistant than 201, but the improvement is not dramatic for general applications.
Applications of 201 Stainless Steel Pipe
201 stainless steel pipes are widely applied in:
- Watch cases, watch bands, and covers
- Decorative tubing and structural components
- Shallow drawing and light industrial products
Applications of 202 Stainless Steel Pipe
The difference between 201 and 202 stainless steel pipes is also reflected in their application scope. Thanks to its better high-temperature resistance, 202 stainless steel is used in:
- Architectural decoration and municipal projects
- Highway guardrails and building handrails
- Shopping malls, hotels, and public facilities
- Glass railings and structural tubing requiring higher durability
Cost and Market Considerations
A practical difference between 201 and 202 stainless steel pipes is cost and availability.
- 202 stainless steel pipe is more expensive and usually requires customized orders from steel mills.
- 201 stainless steel pipe is cheaper, more readily available, and sufficiently reliable for most decorative and industrial applications.
The difference between 201 and 202 stainless steel pipes comes down to composition, strength, corrosion resistance, and application. While 202 performs slightly better in demanding environments, 201 remains the cost-effective choice for everyday decorative and light industrial projects. Buyers should weigh performance needs against budget and supply availability before making a decision.
