Chung Metal supplies Stainless Steel 304L Forgings, the low-carbon version of 304 for welded and forged use where intergranular corrosion is to be prevented. 304L forgings exhibit superior fabricability, weldability, and overall corrosion resistance in normal environments. Our forgings yield clean, dense products with limited inclusions and consistent traceability. 304L forgings are utilized by food processing, pharmaceutical, petrochemical, and architectural engineering industries for parts that require safe corrosion performance and robust mechanical characteristics. Size, finish and certification levels are fulfilled as per customers’ specifications.
SS 304L typically consists of ~18‑20% chromium, ~8‑12% nickel, carbon ≤ 0.03‑0.04%, in addition to Mn, Si, P, S in small quantities. In annealed forged form it contains tensile strength ~485‑620 MPa, yield ~170‑275 MPa, elongation ~40‑50%. It has good ductility and toughness. Hardness moderate. Corrosion resistance in general, mildly acidic, and atmospheric situations is excellent. Forge structure provides better grain structure and strength uniformity. Weldability and formability very good.

Post-forging operations for Stainless Steel 304L include heat treatment, machining, surface finishing, and testing to ensure optimal strength, dimension accuracy, and corrosion resistance.
To determine if Stainless Steel 304L forgings meet your needs, review material certifications, perform quality checks, and ensure they meet required mechanical properties and dimensional standards.
After Stainless Steel 304L forgings, slow cooling in air or controlled environments is recommended to prevent cracking and ensure uniform grain structure and mechanical properties.
304L Forgings are applied to valve bodies, pump housings, flanges, pipe fittings, and structural parts in food, beverage, and pharmaceutical applications where cleanliness and resistance to corrosion are necessary. Also applied in kitchen equipment, hardware in architecture, and decorative or exposed structural elements. In chemical plants, applied to mild acid handling, storage tanks, and pipelines. Forged 304L is also beneficial for components needing high reliability in welding, low distortion, and resistance to intergranular corrosion. Its mechanical, corrosion, and forming properties make it versatile across industries.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
