Stainless steel round pipe 40x1 mm AISI 201 (600 GRIT) — a lightweight structural metal product of precise round gauge, which, thanks to a wall thickness of 1 mm, belongs to the category of thin-walled profiles, providing an ideal balance between high strength and minimal dead weight. Having a standard outer diameter of 40 mm, the product is endowed with an optimized structure, as a result of which the inner through diameter is 38 mm. This engineering ratio of parameters guarantees excellent spatial rigidity of frameworks and high resistance to bending or deformation, allowing the creation of aesthetic welded and prefabricated metal structures, advertising modules, elements of commercial equipment, and exhibition stands without unnecessary load on support nodes. The profile is manufactured using advanced high-precision automatic 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 abrasives makes the weld absolutely imperceptible visually and tactually from the outside, which guarantees flawless architectural aesthetics, affordable market cost, and premium reflective shine for the product. The pipe is supplied in bars with a length of 6 m.
Material of Manufacture and Standards
This profile is manufactured from durable stainless steel grade AISI 201, which is a direct reference analog of the alloy 12X15G9ND according to GOST and the European standard EN 1.4372. Due to the balanced alloying with manganese, nitrogen, and optimal nickel content, this metal has increased mechanical hardness, reliable long-term service in moderate (non-aggressive) operational environments, and is the most economically advantageous solution in its class. 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, high precision of geometric parameters, and maximum strength of the weld joint at molecular levels. 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 1 mm wall, a popular 40 mm gauge, and reference mirror gloss (600 GRIT) makes this pipe a rational and economically advantageous choice for objects with high requirements for design and interior aesthetics. Thanks to the comfortable grip for a human palm, it is an excellent solution for the installation of interior railings, interior stairs, atrium fences, wall-mounted handrails, as well as ergonomic holders in public areas. The model is mass-used for the manufacture of modern commercial equipment, bar counters, furniture for cafes and restaurants, lightweight frames, exhibition and advertising stands, as well as structural and decorative parts in automotive engineering, technology, transport, and mechanical engineering.
Recommended Environment: interiors of modern office, residential, and large shopping centers, exhibition pavilions, premises with low or stable humidity, objects of urban transport, technology, automotive engineering, as well as food blocks (exclusively as auxiliary and decorative elements without direct contact with food or aggressive cleaning substances).
Technical and Operational Limitations:
• Structural Purpose: the product belongs to the category of structural metal products (ASTM A-554) and has a lightweight structure. Due to the thin-walled profile of 1 mm, this pipe is strictly forbidden to be used as a main pipeline in systems under high hydrodynamic, steam, or internal pressure.
• Environmental Specification: the AISI 201 steel grade is not intended for use in environments with constantly high humidity, outdoors under long-term influence of aggressive atmospheric precipitation (rain, snow, fog), as well as in direct contact with industrial alkalis, mineral acids, or chlorine-based compounds.
• Temperature Regime: the profile is designed for moderate thermal loads (resistance to temperature drops is medium). The safe maximum continuous operating temperature is +400°C. Maximum short-term thermal heating is allowed up to +550°C. The minimum operating temperature of exploitation is -40°C.
Technical Recommendations for Mirror Surface Care
Recommended Cleaning Methods:
To preserve the original reference glossy shine of the 600 GRIT surface, mild soapy solutions or specialized chlorine-free disinfectants should be used. Cleaning is performed exclusively with a soft cloth (microfiber) or a foam sponge, which easily remove dust and traces of touch.
Prohibited Care Products:
It is not allowed to use agents containing chlorine, active acids, as well as abrasive powders and stiff metal brushes or scourers. Failure to comply with these rules leads to micro-damage of the passive protective layer of the product, the appearance of scratches, and rapid 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.
