The 316 stainless steel flat bar stock offers a tensile strength of 580 MPa (84 ksi), ensuring exceptional resistance to deformation under heavy loads. This property is critical for structural components in bridges, offshore platforms, and machinery subjected to dynamic stress. The high tensile strength also allows the material to withstand prolonged exposure to mechanical forces without compromising integrity, making it ideal for load-bearing applications like conveyor systems and industrial frameworks.
With a bend strength of 290 MPa (42 ksi), this alloy retains structural integrity even when formed into complex geometries. Its ductility enables seamless fabrication via bending, rolling, or stamping without cracking, making it a preferred choice for architectural trim, marine hardware, and custom brackets. The material’s ability to absorb energy during deformation reduces the risk of sudden failure, ensuring safety in high-stress environments.
Every 316 stainless steel flat bar stock is laser-etched with permanent identifiers, including the grade (e.g., “316” or “316L”), batch number, and manufacturer details. This traceability ensures compliance with international standards like ASTM A276 and EN 10088-2, providing engineers and fabricators with confidence in material authenticity and quality consistency. Laser marking is non-invasive, preserving the material’s corrosion resistance and surface finish.
Accurate weight estimation is essential for logistics and structural design. Use the formula:
Weight (kg/m) = Thickness (mm) × Width (mm) × 8.0 (density) / 1000
Example: A 12mm thick × 75mm wide bar weighs 7.2 kg/m. This calculation helps optimize shipping costs, load distribution, and project budgeting. For imperial measurements, convert dimensions to inches and use density in lb/in³ (0.289 lb/in³).
While 316 stainless steel flat bar stock is highly corrosion-resistant, localized rust may occur under extreme conditions:
