201/202 Stainless Steel Tube

201/202 is a high-manganese, low-nickel, economical austenitic stainless steel, primarily known for its high cost-effectiveness. Its advantages are outstanding: extremely low cost and a significant price advantage. By using manganese to replace some nickel, the raw material cost is far lower than 304, making it the first choice for projects with limited budgets. Surface finishes include 2B, brushed, and mirror finishes, providing excellent decorative effects.

201 (1Cr17Mn6Ni5N) /SUS201

Characteristics: acid and alkali resistant, high density, polishing without bubbles, no pinholes and so on.

Uses: Mainly used for decorative pipes, industrial pipes and some shallow stretching products.

202(1Cr18Mn8Ni5N)/SUS202

Characteristics: With Mn and N instead of part of the nickel, so as to obtain good mechanical properties and corrosion resistance, is a new nickel-saving stainless steel, its room temperature strength is higher than 304, below 800 degrees has good oxidation resistance and medium temperature strength

Uses: Mainly used for decorative pipes, industrial pipes and some shallow stretching products.

Product Form and Manufacturing Process

Production Process: Steel strip rolling + straight seam welding + shaping + polishing

Cross-sectional Shape: Round tube, square tube, rectangular tube (mainly for export)

Surface Treatment: Matte brushed, mirror polished, frosted, sandblasted

Applicable Scenarios: Indoor dry environment decorative structures

Surface Finish Grades:

Brushed/Hairline: Matte finish, durable and scratch-resistant, ideal for handrails and railings.

Mirror Polish: 6K/8K, mirror-like shine, used in interior decoration and display shelves.

Matte Polish: Soft and non-reflective, commonly used for interior ceilings and door frames.

Sand Blasted: High-end texture, fingerprint-resistant, used in upscale decoration.

Features and Advantages:

Highly competitive price, significantly lower than 304 stainless steel, making it the top choice for decoration projects in Southeast Asia, the Middle East, Africa, and South America.

Appearance is very similar to 304 stainless steel, with excellent gloss after polishing, making it difficult to distinguish with the naked eye, satisfying most interior decoration needs.

Good welding and processing performance; easy to cut, drill, bend, and weld, suitable for batch project installations.

High strength and rigidity; not easily deformed when used for railings, supports, and frames.

Fast delivery, complete specifications, ample stock, and quick mold customization of irregular-shaped tubes.

Main export applications: Indoor stair handrails, guardrails, railings; door and window frames, sliding doors, hanging rails; interior decoration of shopping malls/hotels; display racks; furniture frames, table legs, clothes racks, bathroom brackets; lamp holders; billboard frames; interior decorative moldings.

Pickling & Passivation / Acid Wash

Appearance: Matte grayish white, without luster, most commonly used in industrial pipes, the strongest corrosion resistance, often used for fluid pipes, boiler pipes, and chemical pipelines

BA/Bright Annealed

Appearance: Bright, clean, with metallic luster, smooth inner and outer walls, high precision, used for instrument pipes, pneumatic and hydraulic, food hygiene pipes

Polished Surface (Polished)

1.Matte / Brushed / Hairline

Appearance: Fine silk-like texture, soft and not dazzling, suitable for decoration, handrails, guardrails, outdoor projects

2. Mirror Polish

6K / 8K / 10K, the higher the grade, the brighter the appearance, like a mirror surface, clear reflection, used in food and medicine, bathroom, high-end decoration

Warehousing Management

Before each batch of steel leaves the factory, a complete process inspection is strictly carried out. From chemical composition, mechanical properties to dimensional tolerance and surface quality, each item is carefully checked to ensure compliance with national standards and export regulations. At the same time, the quantity, packaging and rust prevention treatment are also verified. An original factory warranty certificate is attached, guaranteeing the quality. Before shipment, inspection photos are provided. Any non-compliant items will not be released, and the quality is fully controllable throughout the process. This ensures your overseas purchasing is safe and worry-free.

All items are visually inspected before delivery. No cracks, deformation, rust, scratches or cutting marks are allowed; edges must be smooth. Only visually sound products will be shipped.

Thickness, width, length, wall thickness, outer diameter have been measured. Straightness, curvature, torsion, diagonal tolerance all meet the corresponding tolerance requirements.

Quality inspection includes: mechanical property tests (yield strength, tensile strength), elongation rate, impact energy, hardness testing, chemical composition testing, process performance testing, etc.

Inspection according to packaging requirements: secure binding, moisture-proof film, rust-proof paper, export fumigation/fumigation-free wooden crates, shipping marks, gross weight, net weight, etc.

We will provide full reception services to support the customers' on-site inspection of the goods.
