- 304 Stainless Steel Construction
- ASTM A269 Certified
- 73,200 PSI Tensile Strength
- Excellent Weldability & Corrosion Resistance
Type 304 is the most versatile austenitic stainless steel, containing 18% chromium and 8% nickel for superior resistance to oxidation and corrosion. This square tubing is manufactured to meet ASTM A269 specifications, ensuring consistent mechanical properties, including 73,200 PSI tensile strength. Its annealed condition makes it non-magnetic and highly formable for a variety of fabrication processes.
As a medium-sized profile, the 3" square dimension offers substantial structural integrity for applications like equipment frames, support posts, roll cages, and architectural handrails where both load-bearing capacity and a clean aesthetic are required. Its 0.120" wall provides a good balance between strength and weight.
