Unique-Bargains 304 Stainless Steel Round Tubing 7mm OD 0.5mm Wall 300mm Length

SKU CH-87A7-XNCAY

304 stainless steel round tube with 7mm outer diameter, 0.5mm wall and 300mm length for structural, decorative or precision fabrication

  • 304 stainless steel delivers high strength and corrosion resistance for long-lasting durability
  • Polished seamless finish provides oxidation resistance and a smooth surface for precision applications
  • 7mm OD with 0.5mm wall thickness ensures consistent dimensions for structural accuracy
  • Threadable and weldable design allows custom fabrication to exact length requirements
  • Suitable for industrial frames, ship models, railings, furniture and decorative craft projects

Precision Tubing for Fabrication

This 304 stainless steel round tube measures 7mm outer diameter with a 0.5mm wall and 300mm length. It suits model engineers, hobbyists and light fabricators who need a small-diameter structural or decorative element. The polished seamless finish resists oxidation and corrosion in indoor or sheltered outdoor settings. Buyers requiring larger bores or heavy-pressure containment should look elsewhere.

Capacity and Workability

The thin 0.5mm wall keeps weight low while the 304 alloy provides good weldability and formability for bending, threading or cutting to custom lengths. It handles low-pressure fluid lines, model ship plumbing, craft frames and furniture accents comfortably. The tube is not rated for high-pressure hydraulic systems or load-bearing columns where thicker wall sections are required.

Thermal and Surface Behaviour

Polished 304 stainless steel conducts heat evenly and does not discolour under normal ambient temperatures encountered in decorative or light-mechanical use. The seamless surface stays smooth during handling, producing no particulate debris or sharp edges that would increase friction or noise in moving assemblies. No external power or cooling is involved in its operation.

Questions about this item

Will the 7 mm OD tube fit inside my existing 8 mm compression fittings?

The tube has a 7 mm outer diameter and 0.5 mm wall, so it should slide into an 8 mm fitting with a small clearance for the ferrule to grip.

How can I confirm the 304 stainless tube is properly welded or threaded after I fabricate it?

A successful joint shows full penetration on a weld bead or clean, burr-free threads that engage a matching fitting without binding.

Does the package include any fittings, cutting tools or protective caps for the 300 mm length?

The box contains only 1 x stainless steel round tube; fittings, cutting tools and end caps must be sourced separately.
