Stainless steel round pipe 40x1.5 mm AISI 201 (600 GRIT) — a durable structural metal product of precise round gauge, which, thanks to an optimal wall thickness of 1.5 mm, provides increased resistance to mechanical loads and excellent spatial rigidity. Having a popular outer diameter of 40 mm, the product is endowed with a balanced structure, as a result of which the inner through diameter is 37 mm. This engineering ratio of parameters guarantees high resistance to bending, torsion, and deformation, allowing the pipe to be used as a reliable basis for loaded load-bearing frameworks, railings, stairs, fencing posts, as well as in the field of auto tuning (in particular, for the modernization of exhaust systems). 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 (while the inner surface remains untreated), which guarantees flawless architectural aesthetics, affordable 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 alloyed 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, long service life in moderate (non-aggressive) operational environments, and is the most rational and 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 geometric roundness of the product, high precision of dimensions along the entire length of the bar, and maximum strength of the weld joint at the molecular level. 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 reinforced 1.5 mm wall, a demanded 40 mm gauge, and flawless mirror gloss (600 GRIT) makes this pipe a multi-purpose material in construction, design, furniture industry, auto tuning, and mechanical engineering. Thanks to the comfortable grip for a palm and high strength, it is an excellent solution for the installation of loaded interior railings, interior stairs, posts for fences, wall handrails, and ladders. The model is actively used in the interiors of modern office and shopping centers, for the design of exhibition pavilions, the creation of commercial equipment, as well as in the form of structural parts in automotive engineering, urban transport, technology, and mechanical engineering.
Recommended Environment: interiors of modern office, residential, and large shopping centers, exhibition pavilions and stands, premises with low or stable humidity, moderate (non-aggressive) industrial environments, objects of urban transport, technology, automotive engineering, and auto tuning.
Technical and Operational Limitations:
• Structural Purpose: the product belongs to the category of structural metal products (ASTM A-554) and has a hollow cylindrical structure. Despite the wall thickness of 1.5 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, 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.
