- 304 Stainless Steel Construction
- ASTM A269 Certified
- 73,200 PSI Tensile Strength
- Excellent Corrosion Resistance & Weldability
Type 304 is the most widely used austenitic stainless steel, containing 18% chromium and 8% nickel for superior resistance to corrosion and oxidation. Manufactured in an annealed condition to ASTM A269 standards, it offers excellent formability and can be easily welded using common techniques. This grade is non-magnetic and cannot be hardened by heat treatment, providing a durable, low-maintenance material solution.
As a medium-sized profile, this 1-1/2" square tube delivers an effective balance of strength, weight, and stability. It is frequently specified for fabricating equipment frames, handrails, support posts, and roll cages where moderate load-bearing capacity and clean aesthetic lines are essential for the final assembly.
