Stainless Steel 304L – Low-Carbon Austenitic Grade for Corrosion Resistance Stainless Steel 304L is the low-carbon variant of the widely used SS 304 grade. Known for its excellent corrosion resistance, superior weldability, and good mechanical properties, 304L is especially suited for applications requiring welding and fabrication without the risk of carbide precipitation. With its lower carbon content (maximum 0.03%), 304L minimizes the possibility of intergranular corrosion in welded structures. It offers a perfect balance of strength, durability, and corrosion protection across a wide range of industries including chemical processing, food handling, pharmaceutical, and marine environments. Key Features: Excellent resistance to oxidation and a wide range of corrosive environments Low carbon content eliminates carbide precipitation during welding Non-magnetic in annealed condition; slight magnetism may occur after cold working Superior formability and machinability Suitable for cryogenic to moderately high temperatures Typical Chemical Composition: Element Content (%) Carbon ≤ 0.03 Chromium 18.0 – 20.0 Nickel 8.0 – 12.0 Manganese ≤ 2.0 Silicon ≤ 1.0 Phosphorus ≤ 0.045 Sulfur ≤ 0.03 Mechanical Properties: Property Value Yield Strength ≥ 170 MPa Tensile Strength ≥ 485 MPa Elongation ≥ 40% Hardness (HRB) ≤ 92 Common Applications: Chemical and petrochemical equipment Food processing and dairy equipment Heat exchangers and pressure vessels Marine components and architectural structures Pharmaceutical and medical-grade equipment Summary: SS 304L is an all-purpose, low-carbon stainless steel offering outstanding corrosion resistance and weldability, making it the ideal material for critical applications where long-term performance and structural integrity are essential.
