Stainless steel round pipe 84x1.5 mm AISI 201 (600 GRIT) — is a high-quality structural rolled metal of a special large caliber, which is an ideal high-strength and cost-effective solution for a wide range of projects. The product has an exact outer diameter of 84 mm and an optimized wall thickness of 1.5 mm, providing an inner through diameter of 81 mm. Such an engineering ratio guarantees excellent lightness of the structure while maintaining high rigidity and resistance to bending or torsion loads. The profile is manufactured using advanced automatic TIG (Tungsten Inert Gas) welding technology in an inert gas environment, which ensures 100% monolithicity, full tightness, and maximum neatness of the welded joint. The seam is located strictly inside the product, and the entire outer surface of the bar undergoes premium multi-stage processing with ultra-fine abrasives to achieve the highest roughness class of 600 GRIT. It acquires a flawless, ultra-smooth mirror shine (chrome effect) that perfectly reflects light, simplifies maintenance, prevents the retention of dust, and gives structures a solid, modern look. The pipe is supplied in standard bars with a length of 6 m.
Material of Manufacture and Standards
This round profile is manufactured from alloyed austenitic stainless steel grade AISI 201 (known domestic analogue is 12Х15Г9НД, European standard is EN 1.4372). A feature of this grade is balanced alloying with manganese and nitrogen, which allows partial replacement of expensive nickel without loss of mechanical strength and ductility of the metal. Due to this, AISI 201 steel has excellent hardness, is perfectly welded, and undergoes mechanical processing, but at the same time is distinguished by a significantly more affordable and favorable cost than the AISI 304 grade. The products strictly comply with the rigorous requirements of international engineering standards ASTM A-554 (USA) for structural pipes and EN 10296-2 (Europe), which guarantees flawless calibrated roundness and wall thickness stability of 1.5 mm along the entire length of the product. The country of origin of the products is Vietnam.
Scope of Application and Purpose
Due to its specific caliber of 84 mm, lightened 1.5 mm wall, premium mirror polishing of 600 GRIT, and affordable price of AISI 201 steel, this profile is a rational choice for many directions:
Automotive Tuning and Exhaust Modernization: design and assembly of elements of automotive exhaust systems, mufflers, resonators, and details of the exhaust tract for modified engines. The large diameter of 84 mm guarantees excellent removal of gases, while a small wall thickness of 1.5 mm allows for a significant reduction in the total weight of the exhaust system.
Interior Railings, Handrails, and Decor: design, manufacture, and installation of staircases, internal handrails, protective railings, bumpers, and decorative elements inside office, shopping, and entertainment centers with a controlled humidity level, where a flawless appearance and high strength are important.
Industrial Equipment and Internal Networks: creation of frame structures, chassis, protective covers, auxiliary lines at enterprises, as well as laying internal technical non-pressure pipelines and ventilation elements for transporting non-aggressive media without pressure.
Technical and Operational Limitations:
• Structural Purpose: the product belongs to the category of structural stainless steel rolled products (standard ASTM A-554). Due to the specific nature of the structural TIG weld seam type, this pipe is categorically forbidden to be used as a high-pressure main pipeline in pressure engineering and utility networks. It is designed exclusively for non-pressure, gravity, or open systems.
• Humidity and Chemical Mode: AISI 201 steel grade has a slightly lower corrosion resistance than AISI 304 grade. Therefore, the pipe is not recommended for use in open outdoor conditions, environments with constant high humidity (swimming pools, saunas, open coastal areas), and highly aggressive chemical environments.
• Temperature Range: the profile is designed for stable operation in a moderate thermal range. The minimum operating temperature is -40°C, the maximum continuous operating temperature is +400°C (short-term peak heating without loss of strength is allowed up to +550°C). Resistance to sharp temperature drops is average.
Technical Recommendations for Mirror Surface Care
Recommended Cleaning Methods:
To preserve the flawless chromed shine of the 600 GRIT coating, mild soapy solutions or specialized disinfectants without free chlorine should be used. Cleaning is performed using a soft cloth (microfiber) or a soft foam sponge, which effectively remove dust, light dirt, and fingerprints.
Prohibited Care Products:
It is categorically forbidden to use cleaning agents based on chlorine, active acids, as well as any abrasive powders, stiff metal brushes, or scourers. Abrasives leave micro-scratches on the gloss, which irreversibly destroys the mirror effect and reduces the protective properties of the outer metal layer.
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, loading and unloading operations, and installation.
