Hicarer 2 Pcs 1-1/2″ OD Stainless Steel Tubing
What you get: two pieces of stainless steel tubing with outer diameter around 1.5 inches, wall thickness about 0.06 inch, and total length of 24 inches. Material is 304 stainless steel for strength and corrosion resistance. Best for short runs, frames, or exhaust-type projects where a longer stock is convenient. Choose this if you need paired tubes with consistent dimensions for quick fabrication.
Best for: hobbyists working on lightweight frames, DIY exhaust sections, or small equipment housings needing repeatable stock. Limitation: not ideal for extremely long spans where extra length is required without splicing.
Vigorous 1-1/2″ OD x 3 Ft. 304 Stainless Steel Tube
This welded stainless steel tube measures 1-1/2″ OD with a 0.065″ wall thickness and is 3 feet long. Made from 304 stainless steel, it provides good strength and corrosion resistance, and welded construction adds durability for bending and forming. Best for longer DIY frames, structural components, or craft projects requiring extended stock. Better for projects needing a longer, continuous section without multiple joints.
Best for: projects that need longer seamless lengths and decent bend tolerance. Caution: ensure your tooling supports 3 ft lengths to prevent warping during cutting and welding.
Hicarer 1 Pcs 1-1/2″ OD 304 Stainless Steel Pipe 36″ Length
This option provides a 36-inch stock length with 1.5″ outer diameter and 0.06″ wall thickness, crafted from 304 stainless steel. It offers a smooth surface and strong service life, suitable for longer runs or custom fabrication where fewer joints are preferred. Best for projects needing extra length without frequent splicing. Limitation: longer stock can be harder to maneuver in tight spaces without proper support and cutting tools.
1.5″ Stainless 180° Mandrel Bend
Material is 304 stainless steel, with 16 gauge (0.065″) wall thickness. The bend is a full 180-degree mandrel type, designed to maintain radius and reduce kinks when forming curves. Best for exhaust fabrication, frames, or art pieces requiring a clean, wide-radius bend. Caution: select the correct bend radius for your design to avoid interference with nearby components.
Vigorous 1-1/2″ OD x 1 Ft. Stainless Tube (2 Pcs)
Two pieces, each 1.5″ OD with a 0.065″ wall thickness and 1 foot length. Welded 304 stainless steel offers good strength and corrosion resistance. Best for small projects or modular builds where a paired supply is helpful for parallel channels or twin rails. Better for projects that need multiple short stock pieces rather than a single long run. Limitation: 1 ft length may require more joints for longer designs.
X AUTOHAUX 4 Pcs 1.5″ Bend Tube Exhaust Elbow
Set includes four 1.5″ elbow bends for fabricating exhaust or tubing runs, using SS304 stainless steel. Wall thickness 0.06″ with good surface treatment. Best for customizing exhaust routes, piping layouts, or frame shaping where multiple bends are needed in a compact kit. Caution: ensure the bend radius and end fittings match your project requirements for a snug fit.
Buying Guide: Key Considerations For 1.5-Inch Stainless Steel Tubing
Material and grade: 304 stainless steel offers corrosion resistance and ease of welding. Confirm the alloy if you expect specific chemical exposure or higher heat.
Wall thickness and diameter: thinner walls are easier to bend, thicker walls provide more strength. For most DIY uses, 0.065″ (1.5 mm) is a practical middle ground.
Length and availability: longer stock reduces joints but can be harder to handle. Stock lengths like 24″ and 36″ cover many common builds; consider whether you’ll need splicing or full-length runs.
Manufacturing quality: look for smooth surfaces, consistent diameter, and straightness. Weldability is important for frames and exhaust components alike.
Cost and quantity: buying in pairs or multiple pieces can be more economical for kits or projects requiring parallel sections.
Compatibility: check end finish and compatibility with your project’s connectors, clamps, or threaded fittings. Some items include bends; others are straight tubes needing additional shaping.
Frequently Asked Questions
- What is the typical use for 1.5″ stainless steel tubing?
Common uses include DIY exhaust sections, frames, furniture supports, and decorative or structural projects. - Is 304 stainless steel suitable for outdoor use?
Yes, 304 stainless offers good corrosion resistance in many outdoor environments, though coastal or highly acidic conditions may require higher-grade stainless. - What wall thickness is easiest to weld?
Approximately 0.065″ (1.5 mm) is a practical thickness that balances strength with weldability for most hobbyist projects. - Should I buy multiple short pieces or one long piece?
It depends on your project layout. Short pieces are versatile for modular builds; long stock minimizes joints but can be harder to manage. - Can these tubes be threaded or bent easily?
Yes, 304 tubes are weldable and can be bent; ensure you use appropriate tooling for precise radii and avoid kinking on bends.
