Advantages of Stainless Steel 304L Hex Bar
- Low Carbon Content – Prevents carbide precipitation, reducing intergranular corrosion risk during welding and high-temperature use.
- Better Weldability β Enables smooth fabrication without post-weld heat treatment, making it ideal for industrial and structural applications.
- Excellent Surface Finish β Provides a polished, clean look, reducing contamination risks in food, medical and pharmaceutical industries.
- Density & Melting Point β High density (8.0 g/cmΒ³) and melting point (1400Β°C) ensure strength and stability in extreme conditions.
- Eco-Friendly & Recyclable β Fully recyclable material, supporting sustainable manufacturing and reducing environmental impact.
Our 304L stainless steel hexagon bars are widely used in oil & gas, chemical, construction, offshore pipelines, pipe works, petrochemical, shipbuilding, hydraulic applications and piping systems. We provide bars ideal for manufacturing fasteners, shafts, valves and structural components, ensuring reliable performance in industries that demand strength, durability and corrosion resistance.
Quality Tests and Certificates
For the purpose of quality assurance, SS 304L hexagonal bar goes through various tests such as Mill Test Certificates, Chemical and Mechanical Reports, PMI Test Reports and Third Party Inspection. All the quality checks are done in the NABL accredited laboratories and this makes all products to be certified for customers.
