- 304 Stainless Steel Construction
- ASTM A276 Certified
- 73,200 PSI Tensile Strength
- Excellent Corrosion Resistance
Type 304 stainless steel is the most common "18-8" chromium-nickel austenitic alloy, delivering a reliable combination of strength, corrosion resistance, and fabricability. Conforming to ASTM A276, this material is provided in an annealed condition, making it non-magnetic and highly ductile. Its excellent weldability and resistance to a wide range of industrial and food-related corrosives make it a foundational material for countless applications.
As a medium-sized 3/8" x 2-1/4" bar, this product provides substantial strength for structural bracing, machine ways, wear strips, and equipment mounting plates. Its dimensions offer a good balance between load-bearing capacity and workability, making it a go-to choice for fabricators building robust frames and supports that must withstand corrosive environments.
