SS 304L – Low-Carbon Stainless Steel for High-Performance Fabrication Stainless Steel 304L is a highly versatile, austenitic stainless steel with a reduced carbon content, specifically designed to prevent intergranular corrosion after welding. It offers all the key benefits of standard 304 stainless steel, with enhanced weldability and corrosion protection. 304L is especially favored in industries where cleanliness, structural reliability, and resistance to harsh chemicals are essential. It retains high ductility and strength while being easily formed and fabricated, even under demanding service conditions. Core Characteristics: Outstanding resistance to rust, chemicals, and mild acids Excellent for welding and heavy fabrication Low carbon minimizes post-weld corrosion Smooth surface finish and cleanability Reliable performance from cryogenic to elevated temperatures Typical Composition (Approx.): Element % by Weight C (Carbon) ≤ 0.03 Cr 18 – 20 Ni 8 – 12 Mn ≤ 2.0 Si ≤ 1.0 Mechanical Properties: Attribute Specification Yield Strength ≥ 170 MPa Ultimate Strength ≥ 485 MPa Elongation ≥ 40% Hardness (max) 92 HRB Primary Uses: Processing plants for food and beverages Welded chemical containers and piping Pharmaceutical-grade equipment Storage tanks, marine and architectural structures Heat-sensitive welded assemblies Conclusion: Whether used in a dairy plant or a heat exchanger, SS 304L delivers durability, cleanability, and corrosion resistance with ease. It’s a trusted material across industries where purity, hygiene, and long-term integrity matter most.
