Stainless steel round pipe 48.3x1.5 mm AISI 201 (600 GRIT) — a high-quality structural metal product of precise round gauge, designed for the creation of durable, lightweight, and aesthetically attractive frame systems. The optimal ratio of the outer diameter of 48.3 mm and the wall thickness of 1.5 mm provides the product with high bending rigidity while maintaining structural efficiency. The inner through diameter of the pipe is 45.3 mm. The profile is manufactured using advanced high-precision automatic TIG (Tungsten Inert Gas) welding technology, which guarantees maximum weld strength. The weld joint is located inside the product, and the outside is subjected to multi-stage mirror polishing with ultra-fine abrasives to the highest roughness class of 600 GRIT (chrome, mirror, gloss). This ensures flawless architectural aesthetics, reference gloss, and surface smoothness, which significantly simplifies maintenance. The pipe is supplied in bars with a length of 6 m.
Material of Manufacture and Standards
This profile is manufactured from high-quality alloyed chromium-nickel-manganese austenitic stainless steel grade AISI 201, which is a direct analogue of the 12Х15Г9НД alloy according to GOST and the European standard EN 1.4372. Due to the balanced chemical composition, where a part of the scarce nickel is replaced by manganese and nitrogen, this steel grade acts as a highly effective and affordable analogue of the AISI 304 grade for moderate operating conditions. Production is strictly regulated by leading international engineering standards ASTM A-554 (USA) and EN 10296-2 (Europe). This guarantees perfect geometric roundness of the product along the entire length of the bar, high calibration precision, and reliability of the weld joint. The country of origin of this series is Vietnam.
Scope of Application and Purpose
The combination of a 48.3 mm gauge, a 1.5 mm wall, and reference mirror gloss makes this pipe the best choice by the "price–quality" criterion for the furniture industry and interior design. It is mass-used for the installation of interior handrails, railings, stairs, and balancing systems, as well as specialized holders for people with special needs in dry rooms. The profile is indispensable in the manufacture of modern commercial and exhibition equipment, bar counters, and furniture frames for the HoReCa segment (for cafes, bars, and restaurants).
Automotive Engineering and Tuning: due to its precise round cross-sectional geometry, light weight, and optimal thermal resistance, the pipe is used for upgrading and building reliable vehicle exhaust systems (manufacture of exhaust tract elements and mufflers).
Recommended Environment: interiors of modern office and shopping centers, exhibition halls and stands, residential and commercial premises with low humidity, production workshops, auxiliary structures of food blocks, as well as engineering and elements of commercial or passenger transport.
Technical and Operational Limitations:
• Structural Purpose: the product belongs to the category of structural metal products (ASTM A-554) and has a hollow structure. Due to the specifics of its purpose and the type of weld joint, this pipe is strictly forbidden to be used as a main pipeline in systems under high hydrodynamic, steam, or any internal pressure.
• Humidity Mode and Environment: due to the reduced nickel content, the AISI 201 grade features average corrosion resistance. Prolonged use of the product in environments with constant high humidity, outdoors under continuous influence of atmospheric precipitation, as well as in direct contact with aggressive chemical compounds and chlorine must be strictly avoided. For such conditions, it is recommended to consider AISI 304 grade steel.
• Thermal Loads: the profile has an average resistance to temperature drops. The safe maximum continuous working temperature is +400°C. Maximum short-term thermal heating is allowed up to +550°C. The minimum operating temperature 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.
