Stainless steel round pipe 76.1x1.5 mm AISI 201 (600 GRIT) — is a high-quality, lightweight, and cost-effective element of large-diameter structural metal products. The product has a precise outer diameter of 76.1 mm and a wall thickness of 1.5 mm, providing an inner through diameter of 73.1 mm. Due to this geometric ratio, the pipe has an optimal balance between bending strength and minimum dead weight, which significantly reduces the load on supporting frames and facilitates installation. The profile is manufactured using high-precision automatic TIG (Tungsten Inert Gas) welding technology in an inert gas environment, which guarantees 100% monolithicity and absolute density of the welded joint. The seam is located 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 mirror shine (chrome effect) that perfectly reflects light, prevents the retention of dust or dirt, and is easy to clean. The pipe is supplied in standard bars with a length of 6 m.
Material of Manufacture and Standards
This round profile is manufactured from austenitic chromium-manganese-nickel stainless steel grade AISI 201 (well-known domestic analogue is 12X15Г9НД, European standard is EN 1.4372). In this alloy, a part of the expensive nickel is replaced with manganese and nitrogen, which significantly reduces the cost of rolled products while maintaining high strength, excellent ductility, and perfect weldability characteristic of austenitic steels. AISI 201 demonstrates excellent stability and corrosion resistance in moderate (non-aggressive) environments and dry operating conditions. Production of this series is strictly regulated by leading international engineering standards ASTM A-554 (USA) for structural pipes and EN 10296-2 (Europe), which guarantees perfect geometric roundness and wall thickness stability along the entire length of the bar. The country of origin of the products is Vietnam.
Scope of Application and Purpose
Due to its large cross-section of 76.1 mm, flawless mirror polishing of 600 GRIT, and the affordable cost of AISI 201 steel, this stainless steel pipe is a rational and commercially justified choice for many technical and decorative tasks inside buildings, as well as in the automotive sector.
Professional Automotive Tuning and Exhaust Systems: the wall thickness of 1.5 mm combined with a diameter of 76.1 mm makes this mirror profile a high-demand material for the design, modernization, and assembly of automotive exhaust systems (exhaust upgrade, manufacturing of mufflers and gas exhaust mainlines).
Interior Construction and Architecture: manufacturing of elegant and durable staircases, handrails, large-diameter railings, atrium enclosures, entrance groups, and separation barriers inside premises with low humidity (office, shopping, and business centers, exhibition halls, galleries, car dealerships).
Commercial Equipment and Design: creation of large advertising and exhibition stands, furniture frames, elements of commercial equipment, branded zones, and racks where a flawless appearance and resistance of the metal to abrasion are important.
Mechanical Engineering and Technology: manufacturing of protective covers, frame details, vehicle body elements, as well as laying internal technical non-pressure pipelines for transporting non-aggressive liquids or gases at enterprises of the mechanical engineering sector.
Technical and Operational Limitations:
• Structural Purpose: the product belongs to the category of structural 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 networks.
• Humidity and Environmental Mode: since AISI 201 steel contains a lower amount of nickel compared to the AISI 304 grade, it is not recommended for use outdoors (street), in coastal marine areas, swimming pools, as well as in environments with constant high humidity or chemical aggressiveness.
• Thermal Loads: the profile is designed for moderate thermal loads with average resistance to temperature drops. The maximum continuous operating temperature is +400°C, short-term peak heating is allowed up to +550°C, and the minimum operating temperature reaches -40°C.
Technical Recommendations for Mirror Surface Care
Recommended Cleaning Methods:
To preserve the original chromed shine of the 600 GRIT coating, mild soapy solutions or specialized disinfectants without free chlorine should be used. Cleaning is performed exclusively with 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 mineral 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 can trigger pitting corrosion of the metal's outer 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.
