201 Stainless Steel Tube – Economical, Corrosion-Resistant & Fabrication-Friendly
Introduction
When you need a stainless tubular that balances price, polish and performance, 201 stainless steel tube stands out. By replacing part of the nickel with manganese and nitrogen, grade 201 delivers tensile strength 10–15 % higher than 304 while cutting material cost by 20–30 %. Its 16–18 % chromium skin resists urban corrosion, mild acids and cleaning chemicals, making 201 stainless steel tube the first choice for furniture frames, handrails, automotive trim and display systems. Whether you buy round mechanical tubing or specify 201 stainless steel square tube for sale, you get weld-ready, mirror-polishable, dimensionally accurate product that ships fast from a reliable 201 stainless steel tube supplier—ideal for decorative and light structural projects where every dollar counts.
Key Features & Benefits
- Lean Austenitic Chemistry – Mn 5.5–7.5 % & N ≤0.25 % stabilise austenite, reduce nickel dependency and keep the alloy surcharge low on every 201 stainless steel tube for sale shipment.
- Higher Cold-Work Strength – Yield ≥310 MPa allows thinner walls, lighter weight and lower freight cost versus 304.
- Seamless & Welded Choices – Cold-drawn seamless for pressure or aesthetic lines; HF-welded for economical structural sections—both in large 201 stainless steel seamless tube stock.
- Square, Rectangular & Oval Profiles – From 10 × 10 mm to 300 × 300 mm square; custom RHS and elliptical shapes available from any leading 201 stainless steel square tube supplier.
- Mirror-Quality Polish – 180G–600G mechanical polish, 8K mirror, satin-brush HL and embossed patterns give showroom-grade reflectivity for handrails and façades.
- Excellent Weldability – Low carbon (<0.08 %) prevents carbide precipitation; TIG, MIG, laser and orbital welding all pass ASTM A554 without post-weld anneal.
- Tight Dimensional Tolerance – OD ±0.1 mm, WT ±8 %, Length 0 – +3 mm; ideal for CNC bending, robotic welding and automated assembly lines.
- 100 % Recyclable – Meets ISO 14021 environmental claims, helping contractors earn LEED credits and green-building certification points.

Applications
201 stainless steel tube is found wherever appearance and cost must coexist. Furniture makers bend square profiles into ergonomic chair frames and table legs; shopping centres use mirror-polished round tubes for handrails and balustrades that meet ASTM A554 loading codes. Automotive tier-1 suppliers form 201 stainless steel square tube into roof-rack rails and exhaust tail-pipe resonators, capitalising on the alloy’s 650 °C oxidation resistance. Supermarkets weld slit-coil tubes into trolley frames and display racks, while food-service factories use sanitary-polished seamless tube for non-corrosive ingredient transfer. Architectural projects from Dubai malls to New York metro stations specify 201 stainless steel square tube for sale as cladding framework, LED light troughs and signage posts. Even solar-panel racking systems adopt elliptical 202 tubes for their superior strength-to-weight ratio and stable 201 stainless steel tube price.
Why Choose 201 Stainless Steel Tube
Compared with 430, 201 stainless steel tube offers far better corrosion resistance and weldability; against 304, it sacrifices only marginal chloride performance yet saves 20–30 % on material cost—budget that can be reinvested in surface polishing or faster delivery. Its higher work-hardening rate allows thinner walls, reducing weight and shipping expense. Leading 201 stainless steel tube supplier and 201 stainless steel square tube supplier also highlight the grade’s stable manganese/nickel balance, ensuring consistent mechanical properties across 1–12 m lengths. Whether you need a mirror-polished handrail or a structural square frame, 201 stainless steel tube gives you 304-like prestige at a 201-like cost.

FAQ
Q1: What is the difference between 201 and 304 stainless steel tube?
A: 201 uses manganese instead of nickel, giving similar strength and urban corrosion resistance at 20–30 % lower cost.
Q2: Is 201 stainless steel square tube suitable for outdoor handrails?
A: Yes, in urban or low-chloride environments; for coastal salt-spray, 316 is recommended.
Q3: Do you keep 201 stainless steel seamless tube stock in standard sizes?
A: Absolutely—OD 6–219 mm seamless tubes in 2B/polish are ex-stock for immediate shipment.
Q4: Can I buy 201 stainless steel tube for sale in custom lengths?
A: Yes, lengths from 0.3 m to 12 m with ±1 mm tolerance, deburred and chamfered ends.
Q5: What certificates are provided?
A: EN 10204 3.1 MTC, dimensional report, and optional SGS/BV third-party inspection.
Q6: How fast can you deliver to Europe?
A: 10-12 days production + 25 days sea freight to Antwerp or Hamburg; urgent air freight also available.
