Advantage
High strength, good impact toughness and good overall and local stress corrosion resistance
Adopt standard 201 and 304 stainless steel, with strictly controlled chemical elements to ensure stable product performance.
304 Stainless Steel: Austenitic stainless steel, C ≤0.08%, Cr 18.00-20.00%, Ni 8.00-11.00%. Excellent corrosion resistance, oxidation resistance and ductility, suitable for medium-corrosion environments and decorative fields.
201 Stainless Steel: Austenitic stainless steel, C ≤0.15%, Cr 16.00-18.00%, Ni 3.50-5.50%. Cost-effective, good mechanical strength and wear resistance, suitable for general industrial and decorative applications with low corrosion requirements.
Size Range
Outer Diameter (OD): Customizable, common specifications from 10mm to 219mm (support special size customization according to customer requirements).
Wall Thickness (WT): 0.8mm - 10mm, optional according to actual application scenarios (light-duty decorative or heavy-duty load-bearing).
Length: Standard fixed length 6m, support custom cut-to-size (0.5m-12m) and random length as customer demand.
Tolerance: Strict dimensional tolerance control (±0.05mm), ensuring precise fit and assembly.
Surface Finish
Mirror Finish (8K Mirror): High-gloss surface, smooth and bright, reflective effect, no scratches or blemishes. Suitable for high-end decoration, furniture, handrails and visible structural parts.
Brushed Finish (No.4 Brushed): Delicate linear texture, matte luster, anti-fingerprint, wear-resistant, easy to clean. Widely used in industrial equipment, architectural decoration, kitchen and bathroom accessories.
Surface Treatment: After polishing, pickling and passivization, the surface is dense and smooth, enhancing corrosion resistance and aesthetic appearance.
Custom Punching Service
Support custom punching according to customer drawings or samples, including round holes, square holes, oval holes and special-shaped holes.
Punching precision: Strict control of hole position, size and spacing, no burrs, no deformation, ensuring the integrity and usability of the pipe.
One-stop service: From raw material selection, surface treatment to custom punching, directly deliver finished products that can be assembled and used.
Mechanical Properties
304 Stainless Steel: Tensile strength ≥515MPa, yield strength ≥205MPa, elongation ≥40%, good ductility and weldability.
201 Stainless Steel: Tensile strength ≥520MPa, yield strength ≥275MPa, elongation ≥40%, high mechanical strength and wear resistance.
All pipes have good pressure resistance and impact resistance, suitable for long-term use in different working environments.
Delivery & Packaging
In Stock Advantage: 304/201 stainless steel round pipes with mirror and brushed finish are in sufficient stock, ready to ship, delivery time 3-7 days for small batches, 7-15 days for large batches.
Packaging: Standard packaging includes bundle (with plastic film wrapping) and plywood case, effectively preventing scratches, rust and damage during transportation.
Delivery Condition: Annealing/pickling/passivization treatment, surface clean and smooth, no oxidation spots, ready for direct use or secondary processing.
Application
Widely used in industrial and decorative fields, including:
Architectural decoration: Handrails, curtain walls, door and window frames, ceiling keels, partition frames.
Industrial equipment: Machinery parts, pipeline systems, support brackets, protective rails.
