What This Product Is For
201 stainless steel pipe is produced as decorative pipe, industrial pipe, boiler pipe to A249 TP201, seamless pipe and A213 TP201 pipe. It carries acid and alkali resistance and high density, and it polishes without bubbles or pinholes. It is used mainly as decorative pipe, industrial pipe and in shallow stretch products such as watch cases and watch strap bottom caps.
Key Benefits
- Polishes without bubbles or pinholes, which is what a decorative finish needs
- High density body suited to shallow stretch forming
- Acid and alkali resistance adequate for interior and light industrial duty
- Available as decorative, industrial, boiler and seamless types
- Lower cost entry point than 304 where rust proofing demands are moderate
Who It Is For
- Furniture and architectural trim manufacturers
- Consumer product makers doing shallow stretch forming
- Light industrial pipework contractors
- Distributors carrying decorative stainless tube
Problems It Solves
- Surface defects that appear when a lower density pipe is polished
- Cost pressure where 304 is specified but the duty is decorative
- Sourcing decorative, industrial and boiler types from separate suppliers
- Forming cracks in shallow drawn consumer parts
Application Scenarios
- Decorative handrail, trim and furniture tube
- Shallow stretch products such as watch cases and strap bottom caps
- Light industrial pipework
- Boiler pipe applications to A249 TP201

Customisation Options
- Decorative, industrial, boiler or seamless type

Use Guide
- Use 201 for interior decorative and light industrial work, and move to 304 where rust proofing matters
- Specify the type as decorative, industrial, boiler or seamless when ordering
- Check the polish specification if the pipe will be visible
- Plan shallow stretch forming around the higher work hardening of 201
How It Compares With the Alternatives
| 304 stainless pipe | 304 stainless steel pipe has better rust proof performance than 201, so 201 is used for decorative and light industrial duty rather than corrosive process service |
|---|---|
| Decorative versus industrial type | Decorative pipe is finished for appearance, industrial pipe for service, and both are produced in this grade |
| Seamless 201 pipe | Seamless 201 has no longitudinal weld, which matters where the tube will be drawn or stretched |
