Stainless steel round pipe 20x1.5 mm AISI 201 (600 GRIT) — a high-strength round structural metal product of precise gauge, made of alloyed austenitic steel. The product has a fixed outer diameter of 20 mm, a thickened wall of 1.5 mm, and an inner nominal diameter of 17 mm. Due to the wall thickness of 1.5 mm, this model features higher rates of rigidity, bending resistance, and overall mechanical strength, making it an ideal choice for structures with high operational and anti-vandal loads. The production is carried out by welding method using advanced TIG technology with complete technological cleaning and multi-stage mirror polishing of the outer weld to a high roughness class of 600 GRIT (chrome, mirror, gloss). The finish processing makes the weld visually imperceptible from the outside, ensuring flawless aesthetics of the product. The pipe is supplied in bars with a length of 6 meters.
Material of Manufacture and Standards
This profile is manufactured from stainless steel of AISI 201 grade, which is an effective and cost-efficient analogue of the 12Х15Г9НД alloy and the European standard EN 1.4372. Due to the optimal alloying with manganese, nitrogen, and nickel, this metal possesses high mechanical strength, hardness, and excellent ductility, and it responds perfectly to standard welding methods and mechanical processing. The AISI 201 modification demonstrates superior wear resistance in moderate (non-aggressive) environments and is more affordable in price compared to high-nickel grades. Production is regulated by international engineering standards ASTM A-554 (USA) and EN 10296-2 (Europe), which guarantees strict compliance with geometric parameters, correct roundness, and maximum reliability of the welded joint. Country of origin — China.
Scope of Application and Purpose
Due to its perfect mirror shine of the outer surface (600 GRIT) and increased strength provided by the thick 1.5 mm wall, this pipe is a versatile material for engineering, design, and architecture. It is massively used for the manufacture of reliable internal railing systems and fences (as a railing pipe and handrail), heated towel rails, modern cafe furniture elements, stable bar counters, as well as sports equipment and exercise machines. The model is in great demand for creating exclusive commercial equipment, designing showrooms, exhibition stands, and advertising structures.
Recommended Environment: enclosed spaces with low and normal humidity levels, offices, residential and shopping centers, exhibition halls, showrooms, as well as industrial production (for auxiliary structures in machinery and engineering).
Technical and Operational Limitations:
• Structural Purpose: the product belongs to the category of structural metal products and is not designed for internal pressure, therefore it is strictly forbidden to use this pipe in hydraulic systems and any pressurized main pipelines.
• Humidity and Chemical Regime: AISI 201 steel grade is not intended for operation in environments with constant high humidity (it is not recommended for use in bathrooms, swimming pools, saunas, or outdoors), as well as in highly aggressive chemical environments.
• Temperature Range: the maximum continuous operating temperature is +400°C, the maximum short-term temperature is up to +550°C, and the minimum operating temperature is -40°C. Resistance to sharp temperature fluctuations is average.
Technical Recommendations for Mirror Surface Care
Recommended Cleaning Methods:
To preserve the original glossy shine of the 600 GRIT surface, mild soapy solutions or specialized chlorine-free disinfectants should be applied. Cleaning is performed exclusively with a soft cloth (microfiber) or a foam sponge. The smooth surface is easily cleaned of dust and contaminants.
Prohibited Care Products:
The use of agents containing chlorine, active acids, as well as abrasive powders and stiff metal brushes is not allowed. Failure to comply with these rules leads to damage to the protective layer, dulling of the gloss, and the appearance of scratches.
The products are delivered in proper commercial condition (new) and protected by a special polymer film, which minimizes the risk of accidental damage and scuffs during logistical operations, storage, and installation.
