Stainless steel round pipe 28x1.5 mm AISI 201 (600 GRIT) — a high-quality structural metal product of precise gauge, manufactured from alloyed stainless steel of the chromium-manganese-nickel group of the austenitic class. The product has a stable outer diameter of 28 mm and an optimal wall thickness for most spatial frameworks of 1.5 mm, thanks to which the inner through diameter is 25 mm. This geometric configuration provides an excellent balance between light weight and high structural strength, guaranteeing the product's resistance to bending, flexing, breaking, or twisting deformations under the influence of design mechanical loads. The profile is manufactured using advanced high-precision 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 visually and tactually absolutely imperceptible from the outside, which ensures a flawless aesthetic appearance and reference reflective shine for the product. The pipe is supplied in bars with a length of 6 meters.
Material of Manufacture and Standards
This profile is manufactured from cost-effective 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. In this alloy, a portion of the expensive nickel is partially replaced by manganese and nitrogen, which significantly reduces the cost of the metal while maintaining high strength, ductility, and a stable austenitic structure. The AISI 201 grade serves as an excellent balanced alternative to more expensive steel grades (such as AISI 304) under conditions of moderate chemical environment aggressiveness. Production is strictly regulated by leading international engineering standards ASTM A-554 (USA) and EN 10296-2 (Europe), which guarantees perfect roundness of the product, precision of geometric parameters, and maximum strength of the weld joint. The country of origin for this series of metal products is Vietnam, whose plants are known for strict quality control and a high level of factory surface polishing.
Scope of Application and Purpose
The combination of an optimal diameter of 28 mm, a 1.5 mm wall, and a bright mirror gloss (600 GRIT) makes this pipe one of the most popular materials for manufacturing interior design elements and durable structures in dry rooms. The model is mass-used for the installation of stylish interior railings, handrails, enclosures, as well as in furniture manufacturing (frameworks of chairs, tables, shelving units) and for the production of modern retail, commercial, and medical equipment. Due to its high strength and excellent appearance, the profile is used to create parts of heated towel rails, elements of vehicle interior decoration, as well as in machinery and mechanical engineering for parts not exposed to aggressive chemical reagents.
Recommended Environment: dry indoor spaces (residential, office, and shopping centers), production halls and food blocks (exclusively as auxiliary metal structures), machinery, mechanical engineering, and internal transport parts.
Technical and Operational Limitations:
• Structural Purpose: the product belongs to the category of structural metal products and is not designed for internal pressure. It is strictly forbidden to use it in hydraulic systems, high-pressure main pipelines, fuel lines, or any systems under high pressure (it is allowed only as a mechanical blank for parts of non-pressure communications).
• Environmental Specification: steel grade AISI 201 has lower corrosion resistance in aggressive environments compared to AISI 304 or AISI 321 steel. The product is categorically prohibited from being operated under conditions of constant high humidity, in the open air without a protective coating, in coastal or marine zones, swimming pools, and highly aggressive chemical environments.
• Temperature Regime: this modification has average resistance to temperature changes. The safe operation range extends from a minimum operating temperature of -40°C to a maximum continuous operating temperature of +400°C. Maximum short-term thermal heating without critical loss of strength is allowed up to +550°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 applied. Cleaning is performed exclusively with a soft cloth (microfiber) or a foam sponge. The mirror surface does not absorb odors and is easily cleaned of dust.
Prohibited Care Products:
It is not allowed to use agents containing chlorine, active acids, as well as abrasive powders and stiff metal brushes. Failure to comply with these rules leads to micro-damage of the passive protective layer of the product, the appearance of scratches, and 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.
