- 304 Stainless Steel Construction
- ASTM A276 Certified
- 73,200 PSI Tensile Strength
- Excellent Corrosion Resistance
Type 304 stainless steel, also known as 18-8, is an austenitic chromium-nickel alloy valued for its superior resistance to atmospheric and chemical corrosives. In its annealed condition, it is non-magnetic and features exceptional ductility and weldability. This flat bar is produced to meet ASTM A276 standards, ensuring consistent mechanical properties and precise dimensions for fabrication.
As a large-profile flat bar, this 3-1/4" wide material is well-suited for heavy-duty applications. Its size makes it ideal for base plates for machinery, heavy structural supports and braces, die components, and custom flanges where significant load-bearing capacity and corrosion resistance are essential.
