High Light	Austenitic Seamless Pipe ，Chrome Manganese Seamless Pipe

Chrome-Manganese Austenitic Seamless Pipe with Mill Test Certificate

The Chrome-Manganese Austenitic Seamless Pipe is an austenitic chromium-nickel-manganese alloy that provides an economical solution for moderately corrosive environments. Compared to standard carbon steel, it delivers superior oxidation resistance and significantly higher mechanical strength.

At ZhongCheng, we manufacture these pipes in strict accordance with ASTM A554 / A312 standards, ensuring precise dimensional accuracy. Whether you require round, square, or rectangular profiles for handrails, automotive components, or industrial frames, our 201 pipes offer consistent weldability and a smooth surface finish.

Key Selling Points

Cost-Effective: Lower nickel content makes it more affordable than grade 304.
High Work Hardening Rate: Ideal for applications that demand high mechanical strength.
Versatile Finishes: Available in 2B, BA (bright annealed), HL (hairline), or mirror finish.
Durable: Resists rust in dry or mildly humid indoor environments.

Manufacturing Process of 201 Stainless Steel Seamless Pipe

Raw Material Inspection: Strict verification of chemical composition.
Slitting & Forming: High-precision coil slitting followed by cold roll forming.
Welding (TIG / Laser): Automated TIG or laser welding with argon shielding to eliminate slag inclusions.
Sizing & Straightening: Ensures outer diameter tolerance within ±0.1 mm.
Heat Treatment: Solution annealing to restore corrosion resistance.
Testing: Eddy current testing (ECT) and hydrostatic testing.
Finishing: Polishing, pickling, or passivation.

Applications

Decorative Tubes: Staircase handrails, balcony railings, gates, and guardrails.
Furniture: Chair frames, table legs, and display racks.
Automotive Industry: Exhaust pipes (low-temperature sections) and trim components.
Construction: Window frames, door frames, and indoor structural supports.
Light Industry: Washing machine drums, bicycle frames, and water heater tanks.

Frequently Asked Questions (FAQ)

Q1: Does 201 stainless steel pipe rust?

A: It is rust-resistant, not rust-proof. It performs well in indoor, dry, or non-saline environments. For coastal or poolside applications, we recommend grade 304 or 316.

Q2: What is the difference between 201 and 304 stainless steel pipe?

A: Grade 201 has lower nickel content (3.5–5.5%) compared to grade 304 (8–10.5%). This makes 201 more economical but slightly less corrosion-resistant. Grade 201 is also harder but somewhat less ductile.

Q3: Can you cut and thread the pipe to my specifications?

A: Yes. We offer custom cutting, threading, grooving, and bending services before shipment.

Q4: Do you provide Mill Test Certificates (MTCs)?

A: Yes. All shipments are accompanied by EN 10204 Type 3.1 or 3.2 Mill Test Certificates verifying chemical and mechanical properties.

Q5: How can I prevent the 201 pipe from rusting?

A: Keep the surface clean and dry. Avoid prolonged exposure to moisture, acids, or salts. Passivation treatment after fabrication is recommended.

Packaging & Shipping

Packaging: Plastic end caps to protect threads; waterproof paper wrapping; wooden crates (for sea freight) or steel pallets.
Loading Port: Tianjin / Shanghai / Ningbo
Lead Time: 7–15 days for standard sizes; 20–25 days for custom orders.
