Stainless steel round pipe 25x1 mm AISI 201 (600 GRIT) — a high-quality structural metal product of precise gauge, manufactured from alloyed austenitic steel. The product has a fixed outer diameter of 25 mm and a wall thickness of 1.0 mm, thanks to which the inner through diameter is 23 mm. This geometric configuration classifies the model as a thin-walled (lightweight) rolled product, which provides an ideal balance of high bending stiffness and minimum mass of the spatial structure. The profile is manufactured using advanced high-precision TIG welding technology with complete technological cleaning and multi-stage mirror polishing of the outer weld to the highest roughness class of 600 GRIT (chrome, mirror, gloss). The finish processing with ultra-fine fraction abrasives makes the weld visually and tactually imperceptible from the outside, guaranteeing flawless aesthetics and maximum mirror shine for the product. The pipe is supplied in bars with a length of 6 meters.
Material of Manufacture and Standards
This profile is manufactured from alloyed stainless steel grade AISI 201, which is a known analog of the domestic alloy 12Х15Г9НД and the European standard EN 1.4372. This alloy acts as a more economically advantageous and affordable alternative to chromium-nickel steel AISI 304, while providing excellent strength indicators, high surface hardness, and superior weldability. Production is strictly regulated by leading international engineering standards ASTM A-554 (USA) and EN 10296-2 (Europe), which guarantees perfect roundness of the product, precision of the declared geometry, and weld reliability. The country of origin for this series of metal products is Vietnam, whose plants are known for strict quality control and a reference level of factory surface polishing.
Scope of Application and Purpose
The combination of a lightweight structure, flawless mirror gloss (600 GRIT), and high mechanical stability makes this pipe an ideal material for interior design and commercial construction. The model is specially designed for operation in conditions where the product is not exposed to excessive influence of aggressive chemical factors. It is mass-used as a primary structural element for creating stylish furniture (for home, offices, and cafes), reliable internal handrail systems, interior guardrails, counters, as well as elements of commercial and exhibition equipment. Due to its perfectly smooth surface and hygiene, the pipe is a high-demand material for the production of modern wardrobe systems (as clothing rails), advertising structures, banner stands, and decorative parts in mechanical engineering and the transport sector.
Recommended Environment: dry indoor premises, office, shopping and entertainment centers, exhibition halls, furniture factories, residential interiors, as well as automotive design and equipment.
Technical and Operational Limitations:
• Structural Purpose: the product belongs to the category of structural thin-walled metal products and is not designed for internal pressure. It is strictly forbidden to use it in hydraulic systems, heating circuits, and any pressurized main pipelines.
• Environmental and Moisture Regime: steel grade AISI 201 has sufficient corrosion resistance in mild conditions but is vulnerable to constant high humidity. It is not recommended to install the pipe outdoors without protection, and it is completely forbidden to use it in environments with constant condensation, chlorides, or in direct contact with sea water and concentrated chemicals.
• Temperature Regime: the model is designed for moderate thermal loads with average resistance to sharp temperature changes. The minimum operating temperature is -40°C, the maximum continuous operating temperature reaches +400°C, and maximum short-term heating is allowed up to +550°C.
Technical Recommendations for Mirror Surface Care
Recommended Cleaning Methods:
To preserve the original glossy shine of the 600 GRIT surface for a long time, mild soapy solutions or specialized chlorine-free disinfectants should be applied. Cleaning is performed exclusively with a soft cloth (microfiber) or a foam sponge. The smooth surface does not absorb odors, does not accumulate bacteria, and is easily cleaned of dust.
Prohibited Care Products:
The use of agents containing chlorine, active acids, alkalis, as well as abrasive powders or stiff metal brushes is categorically not allowed. Failure to comply with these rules destroys the passive protective layer of the steel, leads to the appearance of micro-scratches, and dulling of the gloss.
The products are delivered in proper commercial condition (new) in a protective polymer film, which completely minimizes the risk of accidental damage, scratches, and scuffs during logistical operations, warehouse storage, and installation works.
