Stainless steel round pipe 50.8x1.2 mm AISI 201 (600 GRIT) — is a high-quality element of thin-walled (lightweight) structural metal products of precise round gauge. Due to the optimized wall thickness of 1.2 mm, this profile combines sufficient strength, bending stiffness, and minimal dead weight, which significantly reduces the overall load on structural support nodes and simplifies installation. The outer diameter is 50.8 mm, and the inner through diameter equals 48.4 mm. The profile is manufactured using the automatic TIG (Tungsten Inert Gas) welding method, which guarantees maximum strength and density of the weld seam. The weld joint is located inside the product, and the outside of the pipe is subjected to multi-stage mirror polishing with ultra-fine abrasives to the highest roughness class of 600 GRIT (chrome effect, 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 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, providing high strength at a relatively low cost. Production is strictly regulated by leading international engineering standards ASTM A-554 (USA) for structural steel 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 lightweight 1.2 mm wall, the rigidity of the basic 50.8 mm gauge, and reference mirror gloss makes this pipe the best choice by the "aesthetics–affordability" criterion. The outer diameter is a classic standard for the manufacture of fencing systems, making it perfectly compatible with standard railing hardware. The profile is mass-used for the production of handrails, stairs, light protective barriers, posts, as well as specialized holders for people with special needs in dry premises.
Commercial Design and HoReCa Sector: due to the flawless chrome effect of the 600 GRIT finish, the pipe is indispensable in the interior design of modern restaurants, bars, and cafes. It is used to manufacture elements of bar counters, commercial displays, exhibition structures, frames for lightweight designer furniture, as well as parts for automotive tuning (exhaust system elements without high thermal loads) and passenger transport.
Recommended Environment: interiors of modern office and shopping centers, exhibition halls, residential and commercial premises with low humidity, where there is no contact with water, atmospheric precipitation, or aggressive substances.
Technical and Operational Limitations:
• Structural Purpose: the product belongs to the category of structural metal products (ASTM A-554), features a lightweight structure and a thin wall of 1.2 mm. 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 high-pressure 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, in marine conditions, as well as in direct contact with aggressive chemical compounds and chlorine must be strictly avoided.
• 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.
