Stainless steel tube 12x1.5 mm AISI 201 (600 GRIT) — is a reinforced round structural metal product of precise calibration, featuring the maximum wall thickness in its dimensional class. Manufactured from high-strength alloyed steel, the product has an outer diameter of 12 mm, a wall thickness of 1.5 mm, and an inner diameter of 9 mm. The product is manufactured via advanced TIG welding technology with the external weld seam fully processed and mirror-polished to a high-grade 600 GRIT rating (chrome, high-gloss finish). The inner surface remains unpolished (retaining a durable, uniform internal weld seam), and the joint itself is visually imperceptible from the outside due to the uniform final finish. The tubes are supplied in 6-meter lengths.
Material Specification and Standards
This profile is manufactured from chromium-manganese stainless steel grade AISI 201, which is a well-known analogue of the 12Х15Г9НД alloy and the European standard EN 1.4372. This alloy is non-magnetic and is distinguished by its increased hardness, high resistance to mechanical loads, and optimal cost efficiency. Production strictly conforms to international engineering standards ASTM A-554 (USA) and EN 10296-2 (Europe), which guarantees flawless precision of geometric parameters and high reliability of the weld joint.
Scope of Application and Purpose
Due to the perfect mirror shine of its outer surface (600 GRIT) and the maximum structural strength of the 12x1.5 mm caliber, this tube is perfectly suited for assembling stable handrails, lightweight railings, modern furniture, holders, interior decorative elements, commercial equipment, as well as welded advertising structures, exhibition stands, and showroom interior designs.
Recommended environment: indoor dry premises, office and shopping centers with low and controlled humidity levels, exhibition pavilions, as well as industrial workshops, machinery, and mechanical engineering facilities with a moderate (non-aggressive) operational environment.
Technical and Operational Restrictions:
• Structural application only: this product belongs to the structural metal profile category and is not rated for internal pressure; therefore, it is strictly forbidden to use it in hydraulic systems or any high-pressure pipelines.
• Humidity and environment: AISI 201 grade steel possesses moderate corrosion resistance; therefore, it is not recommended to use the tube in environments with constantly elevated humidity, outdoors in severe climate conditions, or in direct contact with aggressive chemicals.
• 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 reaches -40°C. Thermal shock resistance is rated as medium.
Technical Recommendations for Mirror Surface Care
Recommended Cleaning Methods:
To maintain the original 600 GRIT high-gloss shine, mild soap solutions or specialized chlorine-free disinfectants should be applied. Cleaning must be carried out using only a soft cloth or a foam sponge.
Prohibited Maintenance Methods:
The use of products containing chlorine, active acids, abrasive powders, and stiff wire brushes is strictly prohibited. Failure to comply with these guidelines results in permanent tarnishing and scratching of the mirror surface.
The products are supplied in brand-new commercial condition, wrapped in a protective polymer film to minimize the risk of accidental scratches during logistics, handling, and installation. Country of origin: Vietnam.
