- 304 Stainless Steel Construction
- ASTM A276 Certified
- 73,200 PSI Tensile Strength
- Excellent Corrosion Resistance
Type 304 stainless steel is the most common austenitic "18-8" chromium-nickel alloy, valued for its combination of strength, ductility, and corrosion resistance. In its annealed condition, it is non-magnetic and easily welded. This bar conforms to ASTM A276, ensuring reliable mechanical properties for braces, supports, and framework where both performance and a clean mill finish are important.
As a large 1" x 4" flat bar, this profile provides substantial structural integrity. It is ideal for heavy-duty applications such as machinery base plates, die components, heavy structural supports, and mounting brackets where significant load-bearing capacity and rigidity are essential.
