Stainless steel round pipe 57x1.5 mm AISI 201 (600 GRIT) — is a high-strength, cost-effective element of structural metal products with a round cross-sectional shape, manufactured from alloyed chromium-manganese-nickel austenitic stainless steel. The combination of an outer diameter of 57 mm and a wall thickness of 1.5 mm provides the product with high mechanical strength, excellent bending stiffness, and great resistance to deformation loads across many fields of application. The exact inner through diameter equals 54 mm. The profile is manufactured using the automatic TIG (Tungsten Inert Gas) welding method, which guarantees full monolithicity, high density, and maximum strength of the weld joint along the entire length of the bar. The outer surface of the pipe undergoes thorough multi-stage mirror processing with ultra-fine abrasives with a grit level of 600 GRIT. This creates a flawless chrome effect (gloss, mirror), which gives the product an aesthetic premium appearance, makes it less prone to contamination, and maximizes the ease of sanitary maintenance. The pipe is supplied in standard bars with a length of 6 m.
Material of Manufacture and Standards
This profile is manufactured from steel grade AISI 201 (according to GOST — 12Х15Г9НД, European standard — EN 1.4372). A specific feature of this alloy is the partial replacement of scarce nickel with manganese and nitrogen, which significantly reduces the cost of the rolled metal while maintaining high indicators of mechanical strength, hardness, as well as good ductility and formability. AISI 201 steel exhibits good corrosion resistance in mild (non-aggressive) conditions; however, its application requires monitoring the environmental humidity levels. Production is strictly regulated by leading international engineering standards ASTM A-554 (USA) for structural steel and EN 10296-2 (Europe), guaranteeing perfect geometric roundness and stable calibration along the entire length of the bar. The country of origin of this series is Vietnam.
Scope of Application and Purpose
Due to the perfect balance of an affordable price, high strength, and premium mirror shine of 600 GRIT, the 57x1.5 mm caliber pipe is a rational and very popular choice for a wide range of projects. The outer diameter of 57 mm is a crucial parameter for the precise selection of standard connecting elements and metal hardware.
Fencing, Equipment, and Technological Structures: the pipe is widely used in architecture to create reliable fencing lines, handrails, and elements of modern commercial equipment. The profile is also applied in mechanical engineering, technical devices, transport, and for the manufacture of exhibition hall elements and information stands. It is permitted for use in industry to erect non-pressure pipelines under mild chemical conditions, as well as for heat exchange equipment and auxiliary structures in food processing blocks without direct contact with food products.
Recommended Environment: interior premises of office, shopping, and exhibition centers, dry halls and public catering areas, transport, as well as any moderate environments with low or normal humidity levels.
Technical and Operational Limitations:
• Structural Purpose: the product belongs to the category of structural stainless steel products (ASTM A-554). Due to the specific nature of the structural TIG weld seam, this pipe is categorically forbidden to be used as a high-pressure main pipeline in industrial or municipal pressure engineering networks.
• Chemical and Humidity Mode: due to the reduced nickel content, AISI 201 steel is not recommended for operation in environments with constant high humidity, as well as in aggressive chloride or salty zones. Direct contact of the product with concentrated mineral acids and active alkalis must be completely avoided.
• Thermal Loads: the profile functions stably within a wide temperature range, demonstrating medium resistance to thermal drops. The maximum continuous operating temperature is +400°C, the maximum short-term operating temperature is +550°C, and the minimum operating temperature is -40°C.
Technical Recommendations for Mirror Surface Care
Recommended Cleaning Methods:
To preserve the original mirror shine of the 600 GRIT coating, mild soapy solutions or specialized chlorine-free disinfectants should be used. Cleaning is performed exclusively with a soft cloth (microfiber) or a soft sponge, which effectively remove dust, household dirt, and fingerprints.
Prohibited Care Products:
It is strictly forbidden to use agents based on chlorine, active concentrated acids, as well as abrasive cleaning powders, stiff metal brushes, or scourers. The use of abrasives leaves micro-scratches on the mirror surface, which leads to premature loss of gloss and can trigger localized corrosion on AISI 201 grade steel.
The products are delivered in perfect commercial condition (new). Each bar is supplied in a protective polymer film, which completely guarantees the preservation of the mirror surface against scuffs, scratches, and accidental damage during transportation, logistics, and installation works.
