- 304 Stainless Steel Construction
- ASTM A276 Certified
- 73,200 PSI Tensile Strength
- Excellent Corrosion Resistance & Weldability
Type 304 is the most common austenitic stainless steel, containing 18% chromium and 8% nickel for outstanding resistance to a wide range of corrosive environments. This 4" round bar is produced in an annealed condition, making it non-magnetic and highly formable. It combines good mechanical properties with excellent weldability by all standard methods, making it a reliable choice for fabricated components requiring strength and durability.
As a large-diameter bar, this 4-inch round is ideal for applications demanding substantial strength and mass. It serves as stock for heavy-duty shafts in industrial equipment, large machined parts for manufacturing, structural rollers, and robust forging stock for creating custom, high-strength components.
